GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, NM500 grade material, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. NM500 grade material, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the NM500 grade material steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the NM500 grade material steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.
