Titanium Grade 9 / Ti-3-2.5

UNS R56320
W.Nr 3.7194

Description

Titanium Grade 9 is a near alpha, alpha-beta alloy. It offers much more strength than CP titanium, and unlike Ti-6-4 can be cold worked resulting in moderately high strength and good ductility. It is as weldable as the CP grades and has excellent resistance to corrosion.

Industries Supplied

Architecture, medical, marine, processing & chlorate manufacturing, dimensional stable anodes, and desalination.
