SUS420J1 Stainless Steel Pipe

Characteristics and Application Scope of SUS420J1 Stainless Steel: It has certain wear resistance and corrosion resistance, and a relatively high hardness. Its price is one of the lower categories among stainless steel balls, and it is suitable for working environments with ordinary requirements for stainless steel. It is applicable to all kinds of precision machinery, bearings, electrical appliances, equipment, instruments, meters, transportation vehicles, household appliances, etc. It is mostly used to manufacture parts that are resistant to the corrosion of the atmosphere, water vapor, water, and oxidizing acids.

Material Characteristics of SUS420J1 Stainless Steel Pipe:

Corrosion Resistance: It has good corrosion resistance and can resist the erosion of most common acids, alkalis, and salts. It especially has good tolerance to oxidizing acids and can, to a certain extent, resist the erosion of corrosive media in marine environments and the chemical industry.

Mechanical Properties: It has relatively high strength and hardness. The tensile strength is ≥ 520N/mm², and the yield strength is ≥ 225N/mm². After heat treatment, its hardness and strength can be further improved. At the same time, it has a certain degree of toughness, with an elongation EL (%) ≥ 18, making it suitable for parts that bear high-intensity pressure loads.

Processing Performance: It has good processing performance and can be easily processed into various shapes through hot processing or cold processing methods, such as bending, welding, stamping, etc. It can meet the processing requirements of different products and can produce pipes of non-standard and special models.

Magnetism: It is magnetic and can attract magnets. This characteristic makes it suitable for some application fields that require magnetism.

High-temperature Performance: It has good high-temperature oxidation resistance and can maintain good stability in high-temperature environments, making it suitable for some applications in high-temperature environments.
