Austenitic Stainless Steel with added Titanium

Type 321 stainless is an austenitic steel alloy with added Titanium which acts as a stabiliser.

Titanium content is typically five times that of the carbon content and this addition reduces carbide precipitation during welding and improves elevated temperature properties. Type 321 offers excellent resistance to oxidation and chemical corrosion. The alloy also possesses good creep strength. It can be readily formed or drawn though it is more difficult to form than other austenitic grades. Type 321 is used in a wide range of applications including oil & gas, petrochemical, aerospace and general industry.

Key Features:

Type 321 stainless steel is a variation of grade 304 with the addition of titanium as a stabiliser. The alloy is resistant to intergranular corrosion and can be easily welded and/or formed.
