carbon steel 9 famous mills in Malaysia

The production process of seamless steel pipe for high pressure boiler is more strict than that of EN steel grade S235J2 material ordinary steel pipe. In the process of using seamless steel pipe for high pressure boiler, oxidation and corrosion will occur under the action of high temperature flue gas and steam. Therefore, the requirements for the durability and anti-oxidation corrosion performance of seamless steel pipes for high-pressure boilers are higher, and has requirements for good structural stability.

The EN steel grade S235J2 material plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The EN steel grade S235J2 material products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

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 EN steel grade S235J2 material product workpiece, thereby improving the production efficiency and production processing quality.

Composition characteristics of Q420 alloy steel plate: 1.Low carbon: Due to the high requirements for toughness, weldability and cold forming performance, its carbon content does not exceed 0.20%. 2. Add manganese-based alloy elements. 3. Add auxiliary elements such as niobium, titanium or vanadium, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of the Q420 alloy steel, EN steel grade S235J2 material.
