The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, S450J0 carbon steel plate sheet is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.

In April 2018, our Philiphine customer purchased 1008 Tons API5L Gr.B ERW&Q345B SMLS pipe for offshore oil field resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

S450J0 carbon steel plate sheet, 35CrMo alloy steel is Chinese structual steel. As specified in GBT3077 standard, 35CrMo steel chemical composition should be: Carbon content 0.32-0.40 (C), Silicon content 0.17-0.37 (Si), Manganese content 0.40-0.70 (Mn), Chrome content 0.80-1.10 (Cr), Molybdenum content 0.15-0.25 (Mo). The heating temperature for 35CrMo alloy steel quenching is 850 Centigrade, the cooling material is oil. The heating temperature for 35CrMo alloy steel tempering is 550 Centigrade, the cooling material is oil or water.
