Hot sales A36/SS400/A572 grade 65 carbon steel plate sheet hot rolled plate

09CuPCrNi-A steel belongs to weathering steel. Through alloying of Cu, Mn, Si, Al and simply adjusting part of element content of ordinary low carbon steel (Q235 steel), economic weathering A572 grade 65 carbon steel plate sheet steel with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel. 09CuPCrNi-A steel is mainly used for railway, vehicle, bridge, tower and other steel structures exposed to the atmosphere for a long time.

42CrMo alloy steel A572 grade 65 carbon steel plate sheet: low temperature tempering welding performance thermal processingThe heating temperature is 1150 ~1200°C, the starting temperature is 1130 ~1180°C, the ending temperature is> 850°C, and when φ> 50mm, slow cooling. The normalizing temperature is 850~900°C, and the furnace is air cooled. High temperature tempering: Tempering temperature is 680~700°C, and it is air-cooled from the furnace.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
