Duplex stainless steel, 30 1 stainless steel, 302 stainless steel, 303 stainless steel, 304 stainless steel, 4 10# stainless steel and 420# stainless steel are mostly used for carbon steel blades, manganese steel blades, tungsten steel blades, high carbon steel blades and food blades. According to the blade material classification, it can be divided into: diamond cutter blade, tungsten carbide blade, high-speed steel blade, alloy steel blade, tungsten steel blade, carbon steel blade, manganese steel blade, bearing steel blade, spring steel blade, SKH-5 1 blade, SKD1blade, 9CrSi blade, SKS7 blade and SK2 blade. 9CrSi blade, 6CrW2Si blade, W6Mo5Cr4V2 blade, YG8 blade, YT 15 blade, P20 blade, K30 blade and various imported blade products.
