Stainless steel coils are the basic raw material for both cold-rolled and hot-rolled stainless steel processes. They serve as the precursor base material for various stainless steel sheets, pipes, and stamped parts, encompassing two main categories: cold-rolled and hot-rolled stainless steel coils. The full range covers materials such as SUS200 chromium-manganese-nickel, SUS300 austenitic, SUS400 ferritic/martensitic, duplex steel, and high-temperature resistant special steel. Mainstream grades include 201, 304, 304L, 316, 316L, 321, 310S, 430, 1Cr13, 3Cr13, and 2205.
