What is the basic requirement of steel for boiler pressure vessel
The basic requirements of steel for boiler pressure vessel mainly have the following three aspects(1) having good mechanical properties.(2) having good technical performanceGood corrosion resistance and oxidation resistance
Boilers and pressure vessels work under pressure, some with high temperature or corrosion. According to different working conditions, the boiler and pressure vessel materials roughly divided into two main categories, (a) is used to manufacture at room temperature and medium temperature pressure components of steel plate and steel tube. Should have high room temperature strength. Good toughness. Lower notch sensitivity. Good process performance and welding performance. Have good low power organization. (2) is used to manufacture high temperature and pressure components of steel tube 1, with enough the creep rupture strength, rupture strength and plasticity of 2, 3 with good organization stability at high temperatures, has good high temperature oxidation resistance of 4, has the good processing industrial.
