14Cr1MoR steel how to control the composition to guarantee the properties

Grade:14Cr1MoR
Standard: GB/T 713-2014
14Cr1MoR material is a pressure vessel steel plate, equal to the American standard SA387Gr11cl2 (ASME). It is mainly used for the production of high-pressure boilers and gasifiers in vessels.
 

14Cr1MoR steel properties

The performance of 14Cr1MoR steel plate is stable. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel.
It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate. Strictly control the rolling and heat treatment process, so that the steel plate can obtain a reasonable structure and grain size, and ensure that the 14Cr1MoR steel plate has good comprehensive properties.
 
Application range of 14Cr1MoR steel plate
14Cr1MoR steel plate is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other high-temperature and high-pressure large-scale equipment that is connected to hydrogen or hydrogen mixed media.
