39NICRMO3, a kind of steel, with high strength, toughness and good hardenability and resistance to overheating stability, but the white point of high sensitivity, temper brittleness. Poor welding, welding before the need to be preheated by high temperature, after welding to eliminate stress, the use of quenched and tempered. General production of high strength, good plastic good parts, nitriding after the production of special performance requirements of important parts, such as shafts, gears, fasteners and so on.

Mechanical properties and use
Tensile strength σb (MPa) ≥980 (100), elongation δ5 (%) ≥12, section shrinkage ψ (%) ≥ 55, impact energy Akv (J) ≥78, impact toughness value αkv (J / cm2 ) ≥98 (10) High strength, toughness and good hardenability and resistance to overheating stability with heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery, but high white point sensitivity , There is temper brittleness. Poor welding, welding before the need to be preheated by high temperature, after welding to eliminate stress, the use of quenched and tempered. General production of high strength, good plastic good parts, nitriding after the production of special performance requirements of important parts, such as shafts, gears, fasteners and so on.
