12Cr1MoV hot rolled steel sheet

12Cr1MoV round steel has higher oxidation resistance and thermal strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity in the case of permanent tension; the steel has good manufacturability and weldability, but it needs to be preheated to 300°C before welding and stress relief after welding. deal with. It is a steel grade widely used in high-pressure, ultra-high pressure, subcritical power station boiler superheaters, headers and main steam ducts. It still has high thermal strength and oxidation resistance at 580°C, and 12Cr1MoV steel plate has a higher durable plasticity. The production process is relatively simple, and the welding performance is good, but it is more sensitive to the normalizing cooling rate. Long-term use at 580°C will produce pearlite spheroidization.
