Surface heat treatment methods for EN steel grade S355J2 plates

Mo alloy boiler steel plate EN steel grade S355J2 plates is mainly used for building pressure vessels.The minimum yield strength of SB480M shall be above 275Mpa, and tensile strength of SB480M shall be within 480-620Mpa. For boiler steel plate SB480M with thickness exceeding 38mm shall be normalized when rolling,and belows or equal to 38mm thickness, as rolled is ok. Besides, ultrasonic test is necessary,and high tension, simulated post welded heat treatment shall be chosen by the end users.

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural EN steel grade S355J2 plates steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

Serve our customers with the concept of "being honest and operating with integrity"!

Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of EN steel grade S355J2 plates, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world.
