Analysis of JIS SUS420J1 Stainless Steel
1. Characteristics
JIS SUS420J1 Stainless Steel belongs to martensitic stainless steel. Its chemical composition mainly contains chromium, carbon and other elements. The presence of chromium makes JIS SUS420J1 Stainless Steel has a certain degree of corrosion resistance, and can maintain its own stability in some mild corrosive environment. However, compared to austenitic stainless steels, its corrosion resistance is slightly weaker. In terms of hardness, JIS SUS420J1 Stainless Steel has a high initial hardness, which can be further enhanced by appropriate heat treatment processes such as quenching and tempering. This stainless steel has a certain degree of magnetism, which is one of the typical characteristics of martensitic stainless steel.
2. the advantages
Compared with other types of stainless steel, JIS SUS420J1 Stainless Steel has obvious advantages. First of all, in terms of cost, JIS SUS420J1 Stainless Steel has relatively low raw material costs, which gives it a price advantage in mass production applications. In terms of processing performance, it has good workability, easy to cut, grind and polish and other machining operations, can be easily made into a variety of shapes of parts and products.JIS SUS420J1 Stainless Steel's heat treatment performance is excellent, through the reasonable heat treatment, can be adjusted according to the specific needs of the project's mechanical properties, such as obtaining a higher hardness or better toughness. better toughness.
3. Scope of application
JIS SUS420J1 Stainless Steel has a wide range of applications in many industries. In the machinery manufacturing industry, JIS SUS420J1 Stainless Steel can meet the hardness and abrasion resistance requirements of some mechanical parts that need to withstand a certain degree of friction and abrasion, such as gears, shafts and other parts. In architectural hardware, some hardware fittings with certain requirements for strength and corrosion resistance, such as door handles, locks, etc., can also be manufactured with JIS SUS420J1 Stainless Steel, which can provide a certain degree of corrosion protection while guaranteeing the strength of the product.
