Surface heat treatment methods for S355MC automobile steel plate

EN10028-2 P295GH plate with elevated temperature property gives optimum performance for pressurized products that must support a creep limit greater than 155N/mm2 at 400ºC. S355MC automobile steel plate, P295GH plate is a normalized steel and has excellent welding characteristics. P295GH plates and sheets are used worldwide by fabricators serving the oil and gas industry and can be found in heat exchangers, weldable pressure vessels and boilers and pipework.

Boiler steel is different from S355MC automobile steel plate. Boiler steel is used to make boilers. Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners. Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace. Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers. Their working temperature is higher than other parts, and the environment is also harsher.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the S355MC automobile steel plate product workpiece, thereby improving the production efficiency and production processing quality.

Both parties shall confirm the S355MC automobile steel plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the S355MC automobile steel plate steel plant.
