What kind of stainless steel material can be used as a door?

30 1L? 17Cr-7Ni-0. 1N- low carbon? On the basis of 30 1 steel, the content of C is reduced and the grain boundary corrosion resistance of the joint is improved. By adding N element to make up for the strength deficiency caused by the decrease of C content, the strength of steel is ensured. Railway vehicle frame and exterior decoration materials

304? 18Cr-8Ni? As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (no magnetism, service temperature-196℃~800℃). Household articles (1 and two kinds of tableware, cabinets, indoor pipes, water heaters, boilers, bathtubs), automobile parts (wipers, silencers, molded products), medical devices, building materials, chemicals, food industry, agriculture, and ship parts.

430? 16Cr? As a representative steel of ferritic steel, it has good thermal expansion rate, formability and oxidation resistance. Heat-resistant appliances, burners, household appliances, second-class tableware, kitchen sink, external decorative materials, bolts, nuts, CD sticks, screens.

430J 1L? 18-Cr0.5Cu-Nb- low C.N? Elements such as Cu and Nb are added to 430 steel. Its corrosion resistance, formability, weldability and high temperature oxidation resistance are good. Building exterior wall decoration materials, auto parts, hot and cold water supply equipment.
