201 stainless steel pipe

Short Description:

Marking method

201 stainless steel pipe – S20100 (AISI. ASTM)

American Iron and Steel Institute uses three digits to mark various standard grade malleable stainless steel floors. Including:

① Austenitic stainless steel is marked with 200 and 300 series of numbers;

② Ferritic and martensitic stainless steels are represented by 400 series numbers.

For example, some common austenitic stainless steels are marked with 201, 304, 316 and 310, ferritic stainless steels are marked with 430 and 446, martensitic stainless steels are marked with 410, 420 and 440C, and duplex (austenitic-ferritic) stainless steels, precipitation hardening stainless steels, and high alloys with iron content less than 50% are usually patented or trademarked.

Purpose performance

201 stainless steel tube has the characteristics of acid resistance, alkali resistance, high density and no pinhole. It is used to produce various high-quality materials such as case and bottom cover of watch band. 201 stainless steel pipe can be mainly used in decorative pipe, industrial pipe and some shallow stretched products.
