• 42crmo4 hardness

  • If a destructive accident occurs during the use of the boiler, it will cause serious losses. Therefore, other than some common strengths with 42crmo4 hardness, the boiler steel plate must have good physical properties, mechanical properties and workability, and be strictly specified in the technical terms of the material standard to meet its safety in use. High temperature (above creep temperature) boiler steel plates are generally low-alloy heat-resistant steels, such as chromium molybdenum steel, chromium molybdenum vanadium steel, chromium molybdenum tungsten steel, etc.
