Product Name:

321 321H Stainless Steel Coil

The 321 Stainless Steel (321H stainless steel) is one of excellent resistance to inter-granular corrosion Austenitic types of stainless material by adding Ti, which has better properties especially on resistance of oxidizing acid and weldability, widely used in chemical industry and construction etc.

Peak Metal, always treat quality in company 's heart, provides both 321 stainless steel and 321H stainless steel with grave commitment to endusers abroad, guaranteed material quality and delivery period for all our valued customers.

● Features

1. Non-magnetic, Cr-Ni-Ti austenitic stainless steel with excellent inter-granular corrosion resistance and weldability by adding Ti content.
2. Good corrosion resistance in oxidizing acid and alkali lye, as well as organic & inorganic acid, air and aqueous vapour.
3. 321H is better on bendability and weldability than 321, heat strength property and cold formability processing too.

● Applications

Architecture and Chemical process equipment, such as Aircraft, Seamless pipe, Bolier, Pressure vessel and some parts which are unable to make heat treatment after processing or assembling.
