Type 321 stainless is an austenitic steel alloy with added titanium which acts as a stabiliser.
The titanium content is typically five times that of the carbon content, and this addition reduces carbide precipitation during welding and improves elevated working 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 has usage in a wide range of applications including Oil & Gas, petrochemical, aerospace and general industry.
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 formed.
Commercial applications for this engineering material include:
We stock Type 321 in flats, round bar, plate, sheet, strip, wire, round tube, square bar, hexagon bar, angles, channels and tee sections.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector.
