Welding astm a581 spec steel heat treatment

The JIS G3106 astm a581 spec specification is a hot-rolled carbon steel plate for welded structures. The astm a581 spec steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C, SM570.

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 a581 spec, 42CrMo steel is quenching and tempering.
