201 Stainless steel plate

Material characteristics

201 stainless steel plate is a type of iron chromium nickel alloy steel plate, which has good corrosion resistance, strength and hardness, as well as good plasticity and welding performance. Its tensile strength is 520MPa, yield strength is 270MPa, and elongation is 40%.

Application

201 stainless steel plates are widely used in fields such as construction, furniture, automobiles, ships, chemicals, electricity, petroleum, railways, environmental protection, and pressure vessels. In the field of architecture, it can be used to make door and window frames, curtain walls, staircase handrails, etc; In the field of furniture, it can be used to make countertops, chairs, tables, etc; In the field of automobiles, it can be used to make interior decorations, fuel tanks, etc.

Production process

The manufacturing process of 201 stainless steel plate mainly includes processes such as melting, continuous casting, rolling, annealing, acid washing, etc. Melting is a key process in manufacturing stainless steel plates, which requires controlling the composition and temperature of the molten steel; Rolling is the process of rolling steel billets into steel plates of the required specifications and thickness; Annealing is to eliminate the internal stress generated during the rolling process, improve the flexibility and plasticity of the steel plate; Pickling is to remove oxide scale and impurities from the surface of steel plates, and improve their surface quality.

Surface treatment

There are various surface treatment methods for 201 stainless steel plates, including polishing, sandblasting, wire drawing, coating, etc. Polishing treatment can make the surface of the steel plate smooth like a mirror; Sandblasting treatment can form a uniform rough surface on the surface of the steel plate, improving its adhesion and coating effect; Wire drawing treatment can create delicate textures on the surface of steel plates; Coating treatment can form a thin and hard protective film on the surface of steel plates, improving their corrosion resistance and scratch resistance.

Mechanical properties

The mechanical properties of 201 stainless steel plate mainly include tensile strength, yield strength, elongation, and hardness. Its tensile strength is 520MPa, yield strength is 270MPa, elongation is 40%, and hardness is generally HB187-229. These mechanical performance indicators ensure the application of 201 stainless steel plates in different fields.

Chemical composition

The chemical composition of 201 stainless steel plate mainly includes elements such as iron, chromium, nickel, etc. The content of iron is 73% -85%, the content of chromium is 12% -18%, and the content of nickel is 3% -8%. The ratio of these chemical components makes 201 stainless steel plate have good corrosion resistance and mechanical properties.
