ASME SB337 Grade 1 Titanium UNS R50250 Seamless Pipe
Nov 25, 2025 ASTM-B337.pdf
Products Description
Grade 1 titanium tubing is suitable for environments and applications where stainless steel properties are insufficient. Typical applications include tubing in the aerospace industry and heat exchangers. GNEE's ASTM B338 Grade 1 titanium tubing ranges in outer diameter from 9.53–38.1 mm (3/8–1.5 inches) and wall thickness from 0.7 mm to 5 mm (0.0275 inches to 0.1968 inches). Grade 1 titanium tubing is supplied in straight or U-bend form.
Its yield strength Rp0.2 MPa minimum ranges from 138–310, tensile strength Rm MPa minimum ranges from 240, and elongation A % minimum ranges from 24%.
