Standing at a new historical starting point, we adapt to the requirements of supply side P265GH equivalent astm material structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading p265gh equivalent astm material steel materials supplier.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in p265gh equivalent astm material 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.

16Mo3 steel is a kind of European boiler steel plate. 16Mo3 is different from other raw materials when welding. It must be preheated first, and the weld should be kept for about 30 minutes after the welding is completed. p265gh equivalent astm material, 16Mo3 manganese steel is also an important alloy element steel, it is an important hardenability element. 16Mo3 alloy is a material used at elevated operating temperatures, such as weldable steel in the manufacture of industrial boilers and stainless steel pressure vessels in the petroleum, natural gas and chemical industries.

The black futures market is weakening. Terminal and middlemen are cautious in their inquiry and purchase, and p265gh equivalent astm material merchants have different shipments. However, the factory price of p265gh equivalent astm material keeps rising and the spot bottom is more supportive. The market mentality is still good. The high demand is limited, but the support from the raw material side is strong. It is expected that the p265gh equivalent astm material price will be stable tomorrow.
