201 Stainless Steel Powder Description

201 Stainless Steel Powder is a finely powdered form of stainless steel alloy 201, which is composed primarily of iron, chromium, and nickel. This powder is produced through a process of atomization or grinding of stainless steel ingots or scrap materials. It exhibits a combination of desirable properties, including high corrosion resistance, good formability, moderate strength, and excellent ductility. 201 Stainless Steel Powder is widely used in various industries for its versatility and cost-effectiveness.

Compared with 304 stainless steel, 201 Stainless Steel Powder uses Mn to replace Ni which makes 201 easy to rust. 201 Stainless Steel Powder has higher hardness, worse corrosion resistance, and lower price than 304 stainless steel.
