Characteristics

30CrNiMo8 / 1.6580 is a heat treatable, low alloy steel containing nickel, chromium and molybdenum. It is known for its toughness and capability of developing high strength in

the heat treated condition while retaining good fatigue strength.


Applications

It is used for highly stressed components, where the combination of high strength with tenaciousness is of utmost importance. High cold formability: Parts of different shape can be manufactured, a favorable fibering for stress, a very good surface condition and an high dimensional accuracy. When cold formed the smooth surface leads to an increased fatigue and vibratory strength.


Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210
Density [g/cm3]: 7.82


Soft Annealing
Heat to 650-700oC, cool slowly. This will produce a maximum Brinell hardness of 248.


Normalizing
Temperature: 850-880oC.


Hardening
Harden from a temperature of 830-880oC followed by oil quenching.


Tempering
Tempering temperature: 540-680oC.

Forging
Hot forming temperature: 1050-850oC.


Machinability
Machining is best done with this alloy in the annealed or normalized and tempered condition. It can be machined by all conventional methods.


Corrosion Resistance
This is a low alloy steel and not a corrosion resistant alloy. Protective coating should be used.


Welding
The alloy can be fusion or resistance welded. Preheat and post heat weld procedures should be followed when welding this alloy by established methods.
