440C stainless steel is a high carbon martensitic stainless steel that has high strength, moderate corrosion resistance, and good hardness and wear resistance. Grade 440C is capable of attaining, the highest strength, hardness and wear resistance of all the stainless alloys after heat treatment.
444 stainless steel is mostly popular for its brilliant corrosion resistance and heat resistance just like many other stainless steels. This stainless steel has a wide range of applications and can maintain stable performance in a variety of extreme environments.
305 stainless steel is a common austenitic stainless steel containing elements such as chromium, nickel, and manganese. Chromium is the main anti-corrosion element that combines with oxygen to form a dense oxide film to protect materials from corrosion. Nickel can improve the material's heat resistance and toughness while reducing its magnetism. Manganese can increase the strength and hardness of materials.
309 stainless steel is a stainless steel type with incredible corrosion resistance and high temperature performance. It is widely used in fields such as aviation, chemical industry, and petroleum.
