What are the equivalent steel grades of carbon steel astm a516 grade 70?

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the carbon steel astm a516 grade 70 industry, keep pace with the times, and move towards a new course!

We have very professional workshops for thin plates/ coils, carbon steel astm a516 grade 70, medium and general thick plates. And also special workshop to produce thick plates that thickness is more than 300mm. we produce the steel plate include carbon and low alloy high strength steel plate, shipbuilding and offshore platform steel plate, boiler and pressure vessel steel plate, weather resistant steel plate, pipeline steel plate, alloy steel plate, automobile structure steel plate, and gas cylinder steel coil etc.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the carbon steel astm a516 grade 70 steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

30CrMo 35CrMo 25CrMo4 42CrMo4 and so on CrMo steels have good mechanical properties and hydrogen resistance at room temperature and high temperature. The main alloy elements in CrMo steel are molybdenum, chromium, vanadium, silicon, boron, etc. Molybdenum is a very important alloy element in the hot strength steel. It can significantly improve the hot strength of the CrMo steel, maintain sufficient strength at high temperature, refine the grains and prevent the overheating tendency of the CrMo steel, carbon steel astm a516 grade 70.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for carbon steel astm a516 grade 70, 42CrMo steel is quenching and tempering.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide carbon steel astm a516 grade 70 cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about carbon steel astm a516 grade 70 ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.

The results of adopting two-level carbon steel astm a516 grade 70 service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and carbon steel astm a516 grade 70 after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
