Is it reasonable for SPV490 oil and gas tank steel quenching to get martensite

Pressure vessel steel plate covers a range of steel grades that are designed for use in pressure vessel, boilers, heat exchangers and any other vessel that contains a gas or liquid at high pressures.

Steel applications

Boiler Steel Plate is used for many applications where the pressure inside is significantly higher than atmospheric pressure.More..

Is it reasonable for SPV490 oil and gas tank steel quenching to get martensite

Common medium thick and heavy steel plates are widely used for manufacturing various containers, furnace shells, furnace plates, bridges and automobile static steel plates, low steel alloy steel plates, bridge steel plates, general steel plates, boiler steel plates, pressure vessel steel plates, pattern steel plates, automobile girder steel plates, tractor parts and welding components. SPV490 oil and gas tank steel, bridge steel plates are used for large railway bridges. They are required to bear dynamic load, impact, vibration, corrosion resistance, etc.

According to the market forecast released by Eurofer on August 5, the output of all SPV490 oil and gas tank steel steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the SPV490 oil and gas tank steel steel consumption intensity in the construction industry significantly less than other industries.

The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length SPV490 oil and gas tank steel is suitable for the length required by the construction of steel pipes.

The effect of P and S content on the function of SPV490 oil and gas tank steel, 15MnNiDR steel plate:Phosphorus (P): in general, phosphorus is a harmful element in steel. It will add the cold brittleness, make the welding function worse, reduce the plasticity and make the cold bending function worse.Sulfur (S): sulfur is also a harmful element in general. It makes the steel hot brittle, reduces the ductility and resistance of the steel, and forms cracks during casting and rolling.
