Cold Rolled 2B finish 316L Stainless Steel Strips Coils ASTM A666 JIS G 4305
Description:
Hot rolled stainless steel strip is a semifinished product obtained from the hot rolling of slabs or billets and is produced for conversion by cold rolling.
Cold rolled stainless steel strip is manufactured from hot rolled, annealed and pickled strip by cold rolling on polished rolls. Depending on the thickness desired, the cold rolling requires various numbers of passes through the mill to effect the necessary reduction and to secure the desired surface characteristics and mechanical properties.
Three rolled (unpolished) finishes (No. 1, No. 2 and bright annealed) and one polished finish (mill buffed) are commonly supplied on stainless steel strip.
