Product Description

About products

35CrMo alloy structural steel has high static strength, impact toughness and high fatigue limit, higher hardenability than 40Cr, high creep strength and endurance strength at high temperature, and long-term working temperature up to 500 ºC; Medium plasticity and poor weldability during cold deformation. Low temperature to - 110 ºC, high static strength, impact toughness, high fatigue strength, good hardenability, no tendency to overheat, small quenching deformation, acceptable plasticity during cold deformation, medium machinability, but with the first type of temper brittleness, poor weldability, preheat to 150~400 ºC before welding, and post-weld heat treatment to eliminate stress, generally used after quenching and tempering, can also be quenched or quenched at high and medium frequency surface Use after tempering at medium temperature. Delivery status: normalizing or normalizing+tempering, tempering.
