35CrMo Alloy Seamless Steel Tube has high endurance strength and creep strength at high temperature and good impact toughness at low temperature. 35CrMo alloy steel pipe has high static strength, impact toughness and high fatigue limit, higher hardenability than 40Cr, high creep strength and rupture strength at high temperature. Long-term working temperature of 35CrMo seamless steel tube can reach 500 C. But the weldability of 35CrMo seamless steel tube is not good, and need to preheat to 150 ~ 400 degrees Celsius before welding, and need post-weld heat treatment to eliminate stress. 35CrMo seamless steel tube is generally used after quenching and tempering.
