Description

Structural steel. Parts of high core stability and good toughness like gear parts etc. 

 

Applications
Low and moderately stressed components for vehicles, machines and engines.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [103 x N/mm2]: 210 
Density [g/cm3]: 7.85
Thermal conductivity [W/m.K]: 25.0 

Coefficient of Linear Thermal Expansion 10-6 oC-1

20-100oC 20-300oC 20-500oC
11.1 12.9 13.9


Soft Annealing
Heat to 680-720oC, cool slowly. This will produce a maximum Brinell hardness of 217.

 

Normalizing

Temperature: 860-890oC.

 

Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to 120-200oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

 

Hardening
Harden from a temperature of 820-850oC followed by water or oil quenching. Hardneess after quenching is 52-54 HRC.

 

Tempering
Tempering temperature: 480-60oC, air.

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.

Cold working 
The VMS135 alloy may be cold worked, in the annealed condition, by conventional methods and tooling. It has good ductility.
