1. Description and Application

Quench and tempering special NiCrMo steel, almost equivalent to 34NiCrMo16 steel standardized according to UNI7874/7845, characterized by very high tensile strength together with good toughness. It is usable in the hardened and stress relieved state. It can harden in the air up to thicknesses equal to 90 mm. It is suitable to the manufacture of components of maximum thickness equal to 300 mm strongly stressed and even with a complicated geometry (shafts, torsion shafts, axles, levers, connecting rods, rocker arms). To improve the workability at the machines tools it can be booked with the addition of Ca or re-sulphurized (S60,1%).

The use of re-sulphurized steels involves a worsening of the tensile strength characteristics along the transversal, of the impact strength and of the fatigue strength. Advised austenitic grain dimension > 5 according to UNI 3245 (similar to ASTM E 112-82)

6.HEAT TREATMENT:

Soft Annealing: Heat to 650-680oC, cool slowly. This will produce a maximum Brinell hardness of 269.

Normalizing: Temperature: 850-880oC.

Hardening: Harden from a temperature of 835-865oC, 855-885oC followed by oil or quenching.

Tempering: 550 - 650℃

7.Forging:

Hot forming temperature: 1050-850oC.
