2Cr13-gelegeerd staal is 420 martensitisch staal van "meskwaliteit", vergelijkbaar met Brinell-chroomstaal, het vroegste roestvrij staal. 2Cr13 heeft een bepaalde slijtvastheid en corrosieweerstand, hoge hardheid en de prijs is de laagste onder roestvrijstalen kogels. Het is geschikt voor werkomgevingen met algemene eisen voor roestvrij staal. 2Cr13 gelegeerd staal is geschikt voor alle soorten precisiemachines, lagers, elektrische apparaten, apparatuur, instrumenten, meters, transportvoertuigen, huishoudelijke apparaten, enz. Het wordt meestal gebruikt om onderdelen te vervaardigen die bestand zijn tegen atmosferische druk, stoom, water en oxiderend zuur corrosie. Het overeenkomstige buitenlandse merk van 2Cr13 is ASTM 420, DIN 1.4021, SUS 420J1, GB 20Cr13

Principal Feature:
2Cr13 alloy steel should be classified as stainless steel. A more precise classification should be classified as martensitic stainless iron. It is mainly used for mechanical processing and has better cost performance than normal stainless steel. Therefore, it does not require corrosion resistance. In higher cases, it has been more widely used. After quenching, 2Cr13 can obtain better mechanical properties, has better processability, and has a martensite structure.
Typical Application:
2Cr13 alloy steel mainly used in:
1. Mechanical structural parts, engine exhaust pipes, boiler combustion chambers, and burners.
2. Building exterior decoration materials, automobile parts, hot and cold water supply equipment.
3. It is used in outdoor open-air machines in the chemical, coal, and petroleum industries that require high resistance to grain boundary corrosion, heat-resistant building material parts, and parts that are difficult to heat treat.
Heat Treatment:
Annealing : slow cooling at 800~900℃ or rapid cooling at about 750℃;
Quenching : 920~980℃ oil cooling;
Tempering : rapid cooling at 600~750℃.
Metallographic structure : The structure is characterized by martensitic structure.
