How to identify the quality of 42CrMo4 steel plate by chemical analysis

SA387 Gr 11 Cl 1 steel has high brittle resistance, and also has good impact toughness in low temperature environments. It is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature. The maximum thickness of 42CrMo4 steel plate products can reach 250mm. According to different thickness and impact requirements, the heat treatment of A387 Gr 11 Cl 1 plate can choose normalizing and tempering or normalizing and rapid cooling and tempering.

Different form 42CrMo4 steel plate, boiler steel plate is one of the most critical materials in boiler manufacturing. Boiler steel plate mainly refers to the hot-rolled special carbon steel and low alloy heat-resistant steel plate used to manufacture important components such as the shell, drum, header end cover, support and hanger in the boiler. Boiler steel plates are often working under medium, high temperature and high pressure. In addition to withstand higher temperatures and pressures, boiler steel plates are also subject to impact, fatigue loads, and water and gas corrosion, resulting in poor working conditions.

According to the different heating and melting methods of wear-resistant steel plate, 42CrMo4 steel plate, wear-resistant steel plate also has its own melting welding method. Cast welding is an earlier welding method, which uses the heat released during the oxidation of thermite or magnesium thermite to melt metal: its characteristics are simple equipment and operation, but for wear-resistant steel plate, the welding quality is not high. It is only used to repair the workpiece.
