When weight, corrosion, or service life dictates your expenses, Titanium Square Bar is the perfect choice for your industry. It is suitable for maritime, oil and gas, chemical processing, power, pharmaceutical, electronics, and coating applications when parts are exposed to chlorides, acids, or heat. It is roughly 60 per cent lighter than steel, and its oxide covering is resistant to saltwater and many industrial chemicals. It costs more initially than stainless or carbon steel, and your decision will rely on your load, environment, and maintenance plan. I’ll explain the qualities, ratings, standards, comparisons, and purchase stages below so you can decide with confidence using information you can verify.

What Is Titanium Square Bar and Why Do Its Properties Matter?

A Solid Profile With Four Equal Sides

Titanium Square Bar is a solid metal object that has a square cross shape with equal sides of four. Not like the square tube, which is hollow, not like the flat bar, which has a rectangular section, and not like the round bar, which has a circular section. Engineers use the square profile when they wish to mill brackets, frames, blocks, or bus bars and require material near to final form. At CXMET, we provide it in hot-rolled, cold-drawn, and annealed states with polished, brilliant, machined, or ground surfaces. We cut lengths from 1000 mm to 6000 mm or to your design sizes ranging from 4 mm x 4 mm to 200 mm x 200 mm.

Titanium Square Bar Properties That Decide Performance

Titanium Grade 2 has a density of 4.51 g/cm3, which is around 60 percent of steel. Its elastic modulus is roughly 110 GPa, nearly half that of steel; hence it bends more under strain. It melts at around 1668 °C and resists oxidation at high temperatures. It is resistant to saltwater, chlorine, and many acids because a thin coating of oxide develops on its surface and self-repairs in the presence of oxygen. Titanium is also bio-compatible and non-magnetic. Machining requires care. Heat builds up at the cutting edge, so use sharp tools, consistent feeds, and lots of coolant. To weld, you need an argon shield to stop the oxygen from making the metal brittle.

Estimating Titanium Square Bar Weight Before You Order

Then multiply the cross-sectional area by the length and density. The cross-sectional area of a 50 mm by 50 mm Grade 2 bar one meter long is 0.0025 m². Times 4,510 kg/m^3 and you get roughly 11.3 kg. Add machining allowance and saw cuts to length. Titanium waste is a big cost driver. This easy arithmetic lets you calculate freight, create a material budget, and compare bids per kg to quotes per meter. Grade, condition, size, and how it is processed still determine properties. For crucial items, I would recommend using verified test results rather than vague material claims.

Titanium Square Bar Grades, Standards, and Applications

Commercially Pure and Alloy Grades

We have commercially pure Grades 1, 2, 3, & 4, along with Grades 5, 7, 9, 12, & 23. Of the pure grades, Grade 1 is the softest and simplest to produce, with Grade 4 the strongest. Grade 2 is the standard option for corrosion service. Grade 5, or Ti-6Al-4V, has aluminum and vanadium added. It is substantially stronger. Grade 7 contains palladium to improve its resistance to reducing acids. Grade 12 adds molybdenum and nickel for improved crevice corrosion resistance in hot chloride service. Strength-wise, Grade 9 is between pure titanium and Grade 5. Grade 23 is the low-interstitial variant of Grade 5 for implants and is marketed under the name of Ti-6Al-4V ELI .

Standards and Reference Values

This standard (ASTM B348) covers titanium and titanium alloy bars and billets. ASTM F67 is the specification for unalloyed titanium for surgical implants. ASTM F136 is the specification for Ti-6Al-4V ELI for surgical implants. We adhere to ASTM B348, AMS, DIN, or client tolerances. Minimum values from ASTM B348 and F136 are included in the table as references. Grade 5 gives up some elongation for strength . Grade 2 is ideal for shaping work. All orders are subject to certified mill data.

Grade	Min. yield	Min. tensile	Min. elongation	Typical use
Gr2	275 MPa	345 MPa	20%	Chemical, marine
Gr5	828 MPa	895 MPa	10%	Aerospace, mechanical
Gr23 (F136)	795 MPa	860 MPa	10%	Medical implants

Where Industries Use Titanium Square Bar

Titanium is used by marine and offshore teams in seawater systems and desalination equipment where pitting destroys other metals. It is used in chemical, oil and gas industries for heat exchangers, reactors and pipe portions exposed to chlorides and acids. Titanium is used in electroplating and chlor-alkali lines as bus bars, anode hooks and support frames, usually in the form of square bars, as it conducts current and resists attack. Gas turbines and power plants need heat and fatigue performance. Biocompatibility and corrosion resistance matter to consumers in the pharmaceutical and medical fields; electronics users want non-magnetic characteristics. It’s used by aerospace for structural elements, and by sports and racing teams where reduced bulk pays off. Judge application by load, environment, temperature, and cost of failure in all fields.

Titanium Square Bar vs. Alternative Materials

Titanium Square Bar vs. Stainless Steel

Stainless steel is the normal standard. Titanium Square Bar is about 40% lighter, and Grade 5 has a yield strength greater than the typical 304 and 316 stainless steel. 316 is subject to pitting and crevice corrosion in saltwater and chloride streams. Titanium is immune to both at ordinary temperatures. Stainless steel machines more readily, is cheaper per kg, and is simpler to source in standard sizes. The actual question is life cycle cost. A titanium item that will last a lot longer may cost less in the long run than a stainless part that will need to be replaced every few years. Stainless steel is frequently the reasonable choice in a moderate atmosphere.

Aluminum and Carbon Steel Compared

Aluminum is lighter than titanium, with a density of around 2.7 g/cm3. It also manufactures faster and is cheaper. But it has less strength and a lower temperature limit. Some alloys pit in the presence of chlorides. Titanium is better for greater loads, heat, and saltwater. Carbon steel is the least expensive and simplest to produce. Stiffer, with a modulus of around 200 GPa. But it rusts, therefore requires coatings or cathodic protection in damp or maritime environments, adding upkeep. Titanium Square Bar is seldom a winner on price per kg, but it may win if bulk, corrosion, or extended service life drives the project.

Is Titanium Square Bar Right for Your Industry? A Quick Decision Check

Titanium Square Bar is a good idea when weight savings, resistance to saltwater or chlorides, longevity, minimal maintenance, or verified traceability are most important. Another material can be a better choice if budget is an issue, the item requires heavy forming, delivery dates are short, or temperatures exceed the limits of your selected grade. "And don't just look at the price of the bar. You have to figure the total cost, including certification, machining time, freight, downtime, and cycles of replacement." Don’t make the ultimate judgment on titanium’s reputation; make it on confirmed application facts including chemistry, temperature, load, and target life. Tell us that information, and our staff will assist you in confirming whether titanium is right for you or if a different metal is wiser.

How to Choose and Quality-Check Titanium Square Bar

Start With Your Service Conditions

Specify the operational load, temperature, pressure, vibration, fatigue cycles, corrosion exposure, and desired service life. Note how you will produce the item, via milling, turning or welding. Then match the grade . Corrosion service and forming . Grade 2 . Grade 5 Suitable for high strength and mechanical stresses. Harder chemical lines for 7th and 12th grades. Medical parts are covered by ASTM F136 and F67 and Grade 23. If your project has particular chemical requirements, tell us the desired numbers and we will negotiate a bespoke grade with you.

Write a Complete Specification

A clean design of a Titanium Square Bar saves re-work. Grade, standard, width and height, length, corner radius, straightness, squareness, surface polish, and tolerance. We provide sizes from 4 mm x 4 mm up to 200 mm x 200 mm with surfaces that are polished, pickled, sandblasted, ground, or machined and in hot rolled, cold drawn or annealed condition. Cold drawn & ground bars are often tighter dimensioned, hot rolled bars are used for pieces you will mill intensively. Add cutting waste and machining allowance to your qty. Before buying check certifications, heat traceability, inspection requirements, packaging and any third party testing.

How the Bar Is Made and Inspected

Titanium Square Bar manufacture begins with controlled melting to establish the chemistry, followed by forging or hot rolling, sizing, straightening, annealing and finishing by grinding, peeling or polishing. Temperature and deformation give rise to the grain structure which in turn influences strength and fatigue life. Quality checks should include dimensions, chemical analysis, tensile and hardness testing, visual inspection and non-destructive testing, e.g. ultrasonic inspection if applicable to the application. Heat-number traceability links each final bar to its initial melt and test data. Ask for the mill certificate to view these outcomes. Tell us early if you require special lengths or surface treatment.

Buying Titanium Square Bar: Supplier, Pricing, and Delivery

If your drawing is not complete, provide what you have and we will assist confirm the grade and size against your usage. This saves time for maritime, chemical, medical and OEM applications. Early technical discussions reveal mismatches before anybody reduces content.

Compare Price and Delivery Fairly

Quotes might be per kilo or per meter. Convert both to the same foundation using the actual cross section. Compare total landing cost (freight, packing, tariffs, certification, machining). Price moves with grade, size, tolerance, surface polish and quantity. The additional processing means a cold drawn, ground bar will generally cost more than a hot rolled bar. Clarify the inventory status, manufacturing lead time, and Incoterms with each supplier and inquire how the bars will be wrapped for marine or air freight so that edges and surfaces arrive unharmed. Titanium Square Bar might be expensive at initially, but the extended life span frequently makes the arithmetic work out.

Conclusion

The Titanium Square Bar is applicable to industries which need low weight, corrosion resistance and extended service life, particularly in saltwater, chloride and acid service. This fit is explained by its density of around 4.51 g/cm3, self-repairing oxide film, and the strength of Grade 5. Grade 2 suits corrosion and shaping applications. Grade 5 suits high strength applications . Grade 23 suits implant standards such as ASTM F136. Titanium is generally more costly per kilogram than stainless steel, aluminum, and carbon steel, but it may reduce life-cycle cost when replacement and maintenance is expensive. Good selection is based on clear service data, full specification, and documented traceability. Fair pricing comparison takes into account machining, freight, and certification. If these criteria match your application, titanium is a great contender. If they don’t, another metal may be the right fit.

FAQ

Why Are Grade 2 and Grade 5 Requested Most Often?

Grade 2 offers corrosion resistance, ductility, and easy forming, so it suits chemical and marine parts. Grade 5 offers much higher strength, so it suits mechanical and aerospace parts. Other grades, such as 7, 12, and 23, fit narrower needs like reducing acids, hot brine, or implants.

Is Titanium Square Bar Stronger Than Stainless Steel?

Grade 5 has a minimum yield strength of 828 MPa under ASTM B348, well above common 304 and 316 stainless steel, and it weighs about 40 percent less. Stainless steel can still win on cost and machining ease, so compare both against your load and environment.
