SUS431 is a stainless steel material, which belongs to the Japanese standard martensitic stainless steel, and the main components include iron, chromium, carbon and other elements. This material has good corrosion resistance and work hardening properties, and is widely used in various fields.
SUS431 stainless steel has a high chromium content of about 12-14% and contains a small amount of nickel and silicon elements, the presence of which improves the corrosion resistance of the material and gives it better stability in oxidizing media. In addition, SUS431 stainless steel also has good heat resistance and high temperature strength, which can maintain good mechanical properties at high temperatures.
Due to the high strength and hardness of SUS431 stainless steel and the better work hardening characteristics, its strength and hardness can be improved by cold working deformation. This characteristic allows SUS431 stainless steel to adapt to the processing needs of various complex shapes during the manufacturing process, and is widely used in various industrial fields.
In terms of applications, SUS431 stainless steel can be used to manufacture various parts and products, such as automotive exhaust pipes, fasteners, shaft products, high-strength bolts, etc. Due to its excellent corrosion resistance and mechanical properties, it is also widely used in chemical, petroleum, pharmaceutical and other fields. In addition, in the food processing industry, SUS431 stainless steel is also widely used in the manufacture of various kitchen utensils and food processing equipment.
In conclusion, SUS431 stainless steel is a material with excellent corrosion resistance and work hardening properties, which is widely used in various fields. By understanding its composition and properties, we can make better use of this material and exploit its strengths in different fields.
