What is UNS 201 stainless steel?

Type 201 is an austenitic chromium-nickel-manganese stainless steel that was developed in the 1950's due to worldwide nickel shortages. In the Type 201 composition, manganese and nitrogen are partially substituted for nickel.

Fabrication and Heat Treatment
Forming
Grade 201 stainless steel can be formed using all commonly employed forming methods and pressures similar to that of 300 series stainless steels.


Welding
Grade 201 stainless steel can be welded using all conventional welding techniques.


Hot Working
Grade 201 stainless steel is hot worked at 1149-1232°C (2100-2250°F).


Annealing
Grade 201 stainless steel is annealed at 1010-1093°C (1850-2000°F). Temperature should not be exceeded above 2000°F in order to avoid scaling. It is rapidly cooled to prevent crystallization of carbides.


Applications
Grade 201 stainless steel is used in structural members, different kinds of severely formed parts, and siding and roofing for railway cars and trailers.

     4. Packaging 

    In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：

According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)

GB／T191 packaging-pictorial marking for handling of goods

GB／T4857 (all parts) basic test for transport packages

GB／T4879 rustproof packaging
