DIN/EN 18CrMo4 Alloy Structural Steel 6.0mm-1200mm JIS/KS SCM415

18CrMo4 (1.7243) alloy structural steel has good technological properties and weldability, and has high endurance strength at 500~550 ℃. When the temperature exceeds 550 ℃, the oxidation resistance becomes worse and the creep strength decreases significantly. When the temperature is 500~550 ℃ for a long time, the thermal strength and strength of 18CrMo4 steel decrease.
