Why choose ASTM B348?

Here's the thing – ASTM B348 focuses on bars used for structural and industrial applications. It doesn't just cover one property and call it done.

Common grades like Gr2 and Gr5 are clearly covered. But there's another point worth mentioning: surface condition.

ASTM B348 sets quantifiable limits on allowable surface defects. No vague descriptions like "smooth enough." When we supply to this standard, we verify surface condition before shipment. You don't find surface issues halfway through machining.

So choosing Titanium rod ASTM B348 industrial standard gives you more than just a shape – it gives you a product backed by inspection and data. We provide test reports with every shipment for acceptance and traceability.

Available grades – which one do you need?

Not all applications need the same material properties. Different grades serve different purposes.

Grade	Key Feature	Tensile Strength (MPa)	Typical Applications
Grade 1	Softest, most ductile	≥240	Chemical processing, marine components
Grade 2	Best balance of properties	≥345	Aerospace, heat exchangers, cryogenic vessels
Grade 3	Higher strength than Gr2	≥450	Industrial and marine applications
Grade 4	Strongest commercially pure	≥550	Aerospace components, medical implants
Grade 5 (Ti-6Al-4V)	High-strength alloy	≥896	Aerospace structures, high-performance automotive
Grade 7	Enhanced corrosion resistance	≥345	Chemical processing with aggressive media
Grade 12	Good weldability	≥483	Industrial equipment
Grade 23 (Ti-6Al-4V ELI)	Medical implant grade	≥896	Orthopedic and dental implants

Why Grade 5 is so popular

Grade 5 (Ti-6Al-4V) is the most commonly used titanium alloy. For good reason.

It offers strength comparable to steel at roughly half the weight. The Titanium rod ASTM B348 industrial standard for Grade 5 requires minimum tensile strength of 896 MPa (130 ksi) and yield strength of 827 MPa (120 ksi).

If you're trying to save weight but can't give up strength – this is your grade.

Surface treatment options

Surface Treatment	Characteristics	Best For
Pickling	Matte finish, chemically cleaned	General industrial use
Polishing	Smooth, reflective finish	Medical devices, aesthetic applications
Turning	Precision machined surface	Tight tolerance applications

Where these rods actually get used

Aerospace – Not every titanium rod makes the cut for aerospace. Ours go into structural airframe components, engine accessories, and high-strength fasteners. Save weight, handle heat, don't fail under fatigue.
Medical – Orthopedic and dental implants don't leave room for compromise. Our B348 rods get machined into joint replacements, bone screws, and surgical instruments. Biocompatibility with zero batch-to-batch variation.
Chemical Processing – Heat exchangers, reactor vessels, process piping. Pick the wrong alloy in aggressive media and you've got a real problem. Here, B348 isn't the premium choice – it's the baseline.
Marine – Propeller shafts, subsea connectors, deep-water equipment. Saltwater plus sustained stress kills conventional steels fast. B348's corrosion resistance and fatigue strength actually hold up in brine.

Bottom line: Customers don't pick ASTM B348 because it looks good on paper. They pick it because anything else would be a real problem in these applications.

FAQ

Q: What diameters are available?

A: Titanium rods from 0.125 inches to 2 inches in diameter. Bars larger than 2 inches also available for structural applications. Lengths up to 6000mm.

Q: Do you provide material certificates?

A: Yes. All our Titanium rod ASTM B348 industrial standard products come with MTRs (Material Test Reports) that verify chemical composition and mechanical properties.

Q: What's the typical lead time?

A: Standard sizes in stock – 3–5 business days. Custom sizes or large quantities – 2–4 weeks. Contact us for specific lead times.

Q: Which grade should I pick?

A: Not sure? Tell us what you're making – we'll help you pick. Gr2 is the all-purpose workhorse. Gr5 when you need strength. Gr23 for medical implants.
