If it is thin P235GH steel application parts, then local cooling can be carried out, or according to the length, width and thickness of the cutting parts, in the programming of pre-cooling shrinkage value compensation. The verticality error of the cutting mouth and the steel plate surface should be almost no, that is to say, the cutting mouth and the steel plate surface should be vertical, otherwise the cutting parts will appear size error.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in p235gh steel application etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

The tensile strength of A516 Gr70 plate is 70 kilopounds per square inch, which is more than 482 Mpa as usually known. The main element content of p235gh steel application, A516 Gr70 steel is C Mn Si, and the control of P and S determines its performance. There are few other trace elements. p235gh steel application, A516 Gr70 pressure vessel steel is widely used in petroleum, chemical, power station, boiler and other industries.

According to a report by yonhap news agency on April 26, under the impact of COVID - 19 epidemic, the steel industry chain was also affected. Hyundai lost 29.7 billion won. According to the report, the automobile and other downstream steel industry production stoppage directly led to a precipita-like decline in steel demand, is the main reason for the decline in steel enterprise performance of the main reason for hyundai said, hyundai kia motor production extension, by the end of April is expected to reduce production of 500,000 vehicles, as a result, p235gh steel application, automotive steel demand will be reduced by 300,000 tons.
