GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, 150mm GL-DH 36 TM rolled steel, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.
The company has allocated special environmental protection facilities for all 150mm GL-DH 36 TM rolled steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, 150mm GL-DH 36 TM rolled steel steel mill scale, environmental protection dust has reached 100%.
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 150mm GL-DH 36 TM rolled steel product workpiece, thereby improving the production efficiency and production processing quality.
150mm GL-DH 36 TM rolled steel, ASTM A302 Grade B/A302 Gr.B vessel plates boiler steel sheets are manganese-molybdeum-nickel alloy steel plates, which are widely used in petroleum, chemical industry, power station, boiler, etc, to make the reactor, heat exchanger, separator, spherical tank, liquefied gas, nuclear reactor pressure vessel, boiler steam drum steam, liquefied petroleum, hydropower station and so on.
Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
