As the name implies, automobile steel plate is a special steel plate material used in automobile manufacturing. With the increasing quality of people's lives nowadays, the demand for automobiles is also increasing, making the automobile manufacturing and sales industries very hot in recent years. Automobile steel plates are undoubtedly one of the important materials for automobile construction, and the quality requirements for S355JR carbon steel material, automobile steel plates in automobile manufacturing are also very high. The quality of automotive steel plates is directly related to the quality and safety of automotive products and pricing.

15Mo3 steel plate/sheet is one mainly of Steel for boiler steels.DIN 17155 15Mo3 steel is mainly used for boilers and pressure vessels with elevated temperatures which is equivalent to EN10028 16Mo3 and UNI5869 15Mo3, 15D3 (NFA 36205 ) and ASTM A204Gr.B.

Diffusion annealing of S355JR carbon steel material, wear-resistant plate is to reduce the non-uniformity of chemical composition and structure of metal ingot, casting or forging billet, heating it to high temperature and holding for a long time to make the elements in the steel plate fully diffuse. Due to the long heating cycle and high temperature of diffusion annealing, although the composition of the steel is uniform, the structure of the steel plate is seriously overheated, and the grains grow violently, and the toughness and plasticity are poor. Diffusion annealing is widely used in ingots, casting and forging billets with high quality requirements due to its high energy consumption and serious burning loss.
