201 cold rolled stainless steel strip
Description:
201 stainless steel has certain acid-proof and alkali-proof
properties, high density, no bubble, no pinhole in polishing, etc.
201 stainless steel, with its advantages of low price and low
price, and good household performance, is used to produce all kinds
of high quality materials of watch case and band bottom cover,
etc., and is mainly used for decoration pipe, industrial pipe and
some products of light tensile.
