General Description about 304/304L
Compare to coil, strip, the 304/304L sheets is also the most commonly used material, usually sheets be used by punching and bending as certain size for all kinds of application.
The stainless steel cold-rolled sheet is calendered on the basis of a stainless steel hot-rolled sheet (annealed pickling is generally No. 1 surface). Generally there are 2B, 2D two surfaces, 2D surface is rough, 2B surface is matte, finer, 98% on the market is 2B surface, so generally speaking, stainless steel cold-rolled sheet refers to stainless steel cold-rolled sheet 2B surface. The stainless steel wire drawing plate is processed on a 120#, 180# or even 240# 320# drawing machine on the surface of stainless steel 2B, 2D and even NO.1. Since the hot-rolled surface generally has a large sand hole, it is not suitable as a decorative material and is only used in a very small number of specific industries. Since the stainless steel cold-rolled sheet (especially the surface of 2B) itself has a smooth surface and the effect of the drawn drawing board is good, the stainless steel drawing board which is commercially available is generally made of stainless steel 2B surface.
The stainless steel cold-rolled sheet refers to a steel sheet which has been cold-treated, pickled, and smoothed by a matte roll. Generally used for rust, corrosion and decoration.
Stainless steel cold rolling can be divided into four states: low cold work hardening (DY), semi-cold work hardening (BY), cold work hardening (Y) and special cold work hardening (TY).
