304 stainless steel identities
(1) 304 stainless steel apply the most broad one kind of chromium - nickel stainless steel, takes one versatility the steel, has the good corrosion resistance, the thermal stability, the hypothermia intensity and the physical characteristics; The ramming, curving and so on hot-working are good, non-heat treatment hardening phenomenon (application temperature - 196℃~800℃).
(2) widely applies in food device, the general chemical equipment, the atomic-energy industry and so on.

304 stainless steel surfaces
Cold rolling: 2B (surface luminous), NO.4 (oil mill wiredrawing), HL (wiredrawing surface), BA (mirror surface), No.1 (hot rolling surface)
At present produces 2B the factory to be many, is mainly the Shanxi Taiyuan Steel Works, the Shanghai Baoshan Steel Corporation
The NO.1 habitat has Taiyuan Steel Works, Baoshan Steel Corporation.
