Q370R steel and 15CrMoR plates have low sulfur and phosphorus content, and have good comprehensive mechanical properties, welding performance and low temperature impact toughness. Q370R low alloy steel is suitable for manufacturing medium temperature and low pressure pressure vessels and their accessories. EN 10025 S420ML steel plate, 15CrMoR material has low sulfur and phosphorus content, and has good welding performance and impact toughness.

Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate EN 10025 S420ML steel plate has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts

Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For EN 10025 S420ML steel plate medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
