Stainless steel coils are divided into austenite, ferrite, martensite, dual-phase (ferrite-austenite) stainless steel cold rolled coils and stainless steel hot rolled coils.
Stainless steel plate: divided into cold-rolled plate and hot-rolled plate, its surface has bright surface, matte surface, matt surface. Commonly known as stainless steel plate, there are 2B plate, BA plate.
