Product Introduction

Product Overview

ASTM B348 Titanium Bar is a premium-grade titanium product available in both Commercially Pure (CP) and Titanium Alloy grades, manufactured strictly to ASTM B348 and ASME SB348 standards. Engineered for excellent corrosion resistance, high strength-to-weight ratio, and exceptional biocompatibility, our bars perform reliably under harsh industrial and high-stress environments.

Specifications

Product	Specification(mm)	Grade	Standard	Ultrasonic Standard	Grade of Microstructure	Surface Roughness	Tolerance Range
Billet, Bar & Rod	Ø(5-400) x L	/	ASTM B348	AMS 2631 AMS STD-2154	ETTC2 A1-A9	1.6-3.2μm	h6-h11

Technical Advantages

Resistant to seawater, chlorine, and industrial chemicals, due to titanium's stable oxide layer that protects against pitting and crevice corrosion.

Maintains structural strength while keeping weight low (density ~4.5 g/cm³), enabling lightweight and high-performance designs.

Precision grinding and straightening deliver <0.5 mm/m straightness and h6–h9 tolerances for smooth machining and reduced tool wear.

Controlled vacuum annealing and precision hot rolling deliver consistent yield strength, with Grade 5 (Ti-6Al-4V) bars reliably exceeding 895 MPa tensile strengt

FAQ

Q: What certifications do you provide with the ASTM B348 titanium bars?

A: Every shipment includes an EN 10204 3.1 Material Test Certificate (MTC) detailing the heat number, exact chemical composition, and mechanical test results. We also support third-party inspections like SGS or TÜV.

Q: Can I mix different grades and diameters to meet the 100 kg MOQ?

A: Our standard MOQ is 100 kg per specification for regular production. However, for initial trial orders or stock items, we offer flexibility to help you verify our quality-please contact us with your specific breakdown.

Q: How do you protect the bars from surface damage during international transit?

A: Each titanium bar is individually wrapped in plastic sleeves to eliminate metal-to-metal friction, bundled with protective foam, and securely packed into heavy-duty, export-standard plywood cases.

Q: Do you support custom machining, such as cutting to length or threading?

A: Yes. We provide custom band-saw cutting, chamfering, threading, and custom sizing to meet your exact drawing specifications and reduce your post-processing waste.

Q: What are your standard payment terms for new overseas B2B customers?

A: Our standard terms are 30% T/T deposit in advance and 70% balance payable before shipment. For long-term partners with stable order volumes, flexible credit terms can be negotiated after risk assessment.
