A573 Gr.70 steel and A517 Grade A steel comparison ASTM equivalent steel grade

With high-quality A573 Gr.70 steel and A517 Grade A steel comparison steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our A573 Gr.70 steel and A517 Grade A steel comparison steel market and improved the control of steel plate production quality.

Most of the A573 Gr.70 steel and A517 Grade A steel comparison steel materials used in industrial boilers are carbon steel materials. In a narrow sense, the boiler steel refers to the special steel used for manufacturing industrial boilers and power station boilers, mainly including pressure vessel steel, anti-oxidation steel and hot strength steel. Some of them are carbon steel, most of them are medium and low alloy steel, and a few are high alloy steel A573 Gr.70 steel and A517 Grade A steel comparison. In a broad sense, the boiler steel includes all the steel used to manufacture industrial boilers and utility boilers.

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, A573 Gr.70 steel and A517 Grade A steel comparison, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

A573 Gr.70 steel and A517 Grade A steel comparison, Nickel-based alloys are widely used in petrochemical, metallurgy, energy, and machinery because of their high room temperature and high temperature strength, good oxidation and thermal corrosion resistance, excellent creep and fatigue resistance, good structural stability and reliability. , Building materials, medicine, environmental protection and other industries. The company has developed N08825, N06625, N06600, N06690, N06601 and other nickel-based alloy tube blanks and steel pipe products, which have been implemented in batches in the petrochemical industry.

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 A573 Gr.70 steel and A517 Grade A steel comparison, 42CrMo steel is quenching and tempering.
