ASME SA203 is a low-nickel alloy steel, including five grades of A, B, D, E, and F. SA203 Gr.E steel plate impact temperature -101 ° C. SA203 Gr.D / E / F has good impact toughness and mechanical properties under low temperature working conditions, and is usually used in low temperature environments of -70 ~ -101 ℃ (the tempered state can be -107 ℃). Smelting method: It is smelted by electric furnace + refining outside the furnace + vacuum degassing, and should be fine grain killed steel.
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 42CrMo steel is quenching and tempering.
A709 Gr HPS50W bridge steel plate,Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from . The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.
