So far, our pipeline service customers come from more than 40 countries.
The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. NV D32 ore carrier steel, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
