p265gh carbon steel vs A283 Grade C

Pageviews:

15CrMo alloy plate is a pearlite structure heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature, and P265GH carbon steel has certain hydrogen corrosion resistance. Due to the high content of Cr, C and other alloy elements in 15CrMo alloy plate, the steel has obvious hardening tendency and poor weldability. The weight calculation formula of 15CrMo alloy plate: length × width × thickness × 0.00785 = kg / m. Delivery status of 15CrMo alloy plate: hot rolling, controlled rolling, normalizing, high temperature tempering, QT, etc.

40B steel plate is alloy structural steel plate formed by adding boron to the carbon structural steel with a carbon content of 0.40%. p265gh carbon steel, 40B steel plate has high hardness, toughness and hardenability, and has good comprehensive mechanical properties after quenching and tempering, which can be used instead of 40Cr steel. 40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035. 40B steel plate is used to manufacture parts with larger section and higher performance requirements.

If the chromium content in p265gh carbon steel alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

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.
