The company's main business: ship plate, S420M material low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, S420M material high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional S420M material steel supplier and partner.

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, S420M material, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

API 5CT N80 casing pipe is important equipment for oil drilling . API 5CT N80 casing pipe main application is to support the sidewall of the oil well during drilling. API 5CT N80 oil casing pipe plays an important role to guarantee the normal operation of the whole well drilling work.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, S420M material.

ASTM A537 class 1 boiler plate is pressure vessel steel. S420M material, A537 class 1 boiler plate chemical elements include C, Si, Mn, P, S, Mo, Ni, etc. Among them, the carbon content is 0.24 max., Si content is 0.13-0.55%, Mn content is 0.92-1.72%, the max. contents for both P and S are 0.035%, the Mo content is 0.09% max, and the Ni content is 0.38% max. A537 class 1 boiler plate properties: A537 class 1 boiler plate tensile strength is 450-585 MPa, min. yield strength is 310 MPa, and min. elongation in 2 in.(50mm) is 18%.

We are leading supplier of pipeline steel. The pipeline steel in usually in forms of pipeline steel coils, pipeline steel sheet, pipeline steel plate and pipeline steel pipes. And the most popular standard is API 5L. For questions about S420M material pipeline steel, such as X70 steel properties, API 5L X42 steel properties, difference between API 5L PSL1 and API 5L PSL2, API 5L grade B steel price, please feel free to communicate with us.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
