ASTM 4135 alloy structural steel pipe has high static strength, impact toughness, and high fatigue limit. Its hardenability is higher than that of 40Cr steel, and it can maintain high creep strength and durable strength at high temperatures, and its long-term working temperature can reach 500°C. During cold deformation, its plasticity is at a medium level, but its weldability is poor. At low temperatures of -110 degrees Celsius, it has high static strength, impact toughness and high fatigue strength, good hardenability, no overheating tendency, small quenching deformation, and acceptable plasticity during cold deformation. The resistance is at a medium level, but it has the first type of temper brittleness and poor weldability. It needs to be preheated to 150~400 degrees Celsius before welding, and post-weld heat treatment is required to eliminate stress. Generally, it is used after quenching and tempering, and can also be used after high and medium frequency surface quenching or quenching and low and medium temperature tempering. | |||||||||
