Physical and chemical properties:

physical properties

Modulus of elasticity: The modulus of elasticity of 201 stainless steel coil is about 29,000,000 psi.

Thermal conductivity: The thermal conductivity of stainless steel is worse than that of ordinary carbon steel, but it has advantages in some applications that require heat preservation or insulation. Its thermal conductivity is about 16.3 W/(m · K).

Magnetic: Some stainless steel coils such as martensitic stainless steel are magnetic, while austenitic stainless steel is basically non-magnetic, but under specific conditions such as cold working, austenitic stainless steel may also produce magnetism.

Strength: It has high strength, including yield strength and tensile strength, and can withstand certain external forces and loads. For example, the tensile strength of 304 stainless steel coil is generally above 500MPa.

Ductility: Good ductility allows it to be processed into various shapes, such as bending, stretching, stamping, etc., without easily breaking.

chemical properties

Corrosion resistance:

Stainless steel coils contain chromium, nickel and other elements. Chromium can form a dense chromium oxide passivation film on the surface, which makes stainless steel have good corrosion resistance and can resist the corrosion of atmospheric, water, acid, alkali, salt and other media.

Oxidation resistance: In high temperature environments, stainless steel coils can maintain good oxidation resistance and are not easy to be oxidized. They can be used for high-temperature stoves, automotive exhaust systems and other components.

High temperature resistance: Stainless steel coils of different materials have different high temperature resistance. For example, 310S stainless steel coils can be used for a long time at temperatures around 1000 ° C, while 304 stainless steel coils have good stability below 800 ° C.

Low temperature resistance: Some stainless steel coils can still maintain good toughness and strength in low temperature environments, and can be used in cryogenic equipment and projects, such as liquid nitrogen storage containers.

Application:

Stainless steel coils are extremely widely used. In the construction field, they are used for curtain walls, roofs, decorative panels, etc. They are beautiful and corrosion-resistant and can resist wind and rain erosion for a long time. In terms of automobile manufacturing, they can be processed into components such as body panels and exhaust pipes. They have both strength and corrosion resistance and improve the performance and lifespan of automobiles. In the home appliance industry, they are made into shells and internal components of refrigerators, washing machines, etc. They are hygienic and easy to clean and meet the requirements of the home appliance use environment. When food is processed, it is often used as the material of food processing equipment to ensure food safety and hygiene. In addition, it also plays an indispensable role in many industries such as chemical industry and mechanical processing.
