What is the hardness of 2Cr13 stainless steel?
Leave a message
2Cr13 stainless steel equivalent standards include the following:
ASTM standard: 420
AISI/SAE standard: 420
UNS standard: S42000
EN standard: 1.4021
JIS standard: SUS420J1.
2Cr13 stainless steel has a wide range of hardnesses, depending on heat treatment conditions.
Effect of quenching temperature on hardness: The quenching temperature of 2Cr13 stainless steel has a significant impact on its hardness. When the quenching temperature is between 980℃ and 1050℃, the hardness is between 45 and 50HRC. If the quenching temperature is higher than 1050°C, the hardness will increase by about 2HRC, but at this time the structural grains of the steel will become coarser and the brittleness will also increase.
Other heat treatment conditions:
In addition to the quenching temperature, the tempering treatment after quenching also affects the hardness. The hardness of 2Cr13 stainless steel after quenching and tempering can reach HRC52-65 degrees. In addition, the hardness of 2Cr13 stainless steel can be significantly improved after nitriding treatment. The hardness of the nitrided layer can reach up to 1270 HK, which is 4.4 times the hardness of the substrate.
Different hardness testing methods:
The hardness of 2Cr13 stainless steel can be measured by a variety of testing methods, including Rockwell hardness (HRC), Vickers hardness, and Brinell hardness.
Its Rockwell hardness is about HRC55, Vickers hardness is about 400, and Brinell hardness is about 200.
