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 P355GH material specification, 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.

Heat treatment specification and microstructure of p355gh material specification, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).

Try to use p355gh material specification high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the p355gh material specification temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service.
