Grade astm a204 grade b ASME equivalent steel

The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy astm a204 grade b products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of astm a204 grade b stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

NM450 material is mainly to provide protection in occasions or parts where wear resistance is needed, so that the life of the equipment is longer. Then it can reduce the maintenance and downtime brought by maintenance, and accordingly reduce the investment of funds. astm a204 grade b, NM450 wear-resistant steel plate is widely used in engineering machinery, mining machinery, coal mine machinery, environmental protection machinery, metallurgical machinery, abrasive tools, bearings and other product parts.

Compared with ordinary steel, the astm a204 grade b special steel has the following characteristics. First, the special steel has better physical properties, higher strength, stronger compressive strength, and better precision. Second, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance. Third, the composition of the special steel is more diversified, which can be synthesized by integrating other elements, such as alloy steel, high carbon steel, etc. Fourth, special steel is more flexible for processing.

astm a204 grade b, 45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.

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 astm a204 grade b, 42CrMo steel is quenching and tempering.
