How to choose the a516 grade 70 bar thickness

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, a516 grade 70 bar seamless steel pipes for ships and petroleum cracking a516 grade 70 bar steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many a516 grade 70 bar products have been exported to the Middle East, India, Southeast Asia and Europe and America.

We have gradually formed four advantageous products of steel plate, steel pipe, a516 grade 70 bar, stainless steel and special steel, and established our own processing center to meet the diversified needs of customers. At the same time, we also set up professional environmental protection, baby carriage and other projects. With the professional team and strong background of steel plate, steel pipe, stainless steel and special steel, it will drive the rapid development of other projects.

The main difference between a516 grade 70 bar, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

a516 grade 70 bar, 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.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. a516 grade 70 bar, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
