15CrMo steel belongs to Pearlite Heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature (generally not more than 600 ℃), and has certain hydrogen corrosion resistance. So S900MC automotive steel supplier, 15CrMo steel is widely used in petrochemical industry. However, due to the high content of Cr, C and other alloy elements in the steel, the hardening tendency of 15CrMo steel is obvious and the weldability is poor. The main problems are hardening in heat affected zone, cold cracks and reheat cracks during post weld heat treatment.

As to the Chemical composition, the different content is a main on carbon content, while the carbon content of S900MC automotive steel supplier, A283Gr. D is no more than 0.27% and it is higher than Grade C (≤0.24%) ; as to the mechanical property, the differences are tensile strength and yield strength, while the tensile strength of ASTM A283 Gr.D is 415-550MPa (60-80 ksi) and yield strength of ASTM A283 Grade D is 230MPa (33 ksi).

Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some S900MC automotive steel supplier, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.
