alloy steel SA633 Gr E carbon steel plate sheet vs stainless steel

The thickness of our pressure vessel plates, SA633 Gr E carbon steel plate sheet generally ranges 5 to 200mm. According to the working conditions and processing technology of the container, the pressure vessel plate must have good cold bending and welding performance; good plasticity and toughness; high temperature short-term strength or long-term strength performance. In order to make the container can withstand higher pressure and reduce the weight of the structure itself, in addition to high-quality carbon steel, pressure vessel plate is currently made of low-alloy structural steel.

SA633 Gr E carbon steel plate sheet, 12Cr1MoV steel is alloy structure steels, and it is usually produced into 12Cr1MoV steel coil, 12Cr1MoV steel sheet, 12Cr1MoV steel plate, 12Cr1MoV steel bar, etc. 12Cr1MoV steel is composed of Carbon, Silicon, Manganese, Chrome, Molybdenum and so on chemical elements. Amng them, the C content is 0.08-0.15, Si 0.17-0.37, Mn 0.40-0.70, Cr 0.90-1.20, Mo 0.25-0.35. The tensile strength of 12Cr1MoV steel is not lower than 490 Mpa, and yield strength is not lower than 245 Mpa.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
