Ti-Grade 12

Trade name	Ti 3Al-1,5Mn

Standards

Material No.

3.7105

EN Designation

Titan Grade 12

ASTM

Ti-Grade 12

UNS

R53400

Description	Ti-Grade 12; Titanium - 0.3%Mo - 0.8%Ni

Special properties	Low-alloy titanium materials were mainly developed for use in the chemical industry. They offer the same excellent properties as pure titanium grades together with improved corrosion resistance. This is achieved by means of minor additions of Pd and Ni + Mo, which raise their resistance to reducing solutions and reduce their susceptibility to crevice corrosion, especially in chloride-containing media.
