28Mn6 Description
Manganese steel for moderate and lower temperature use in pressure vessels.
28Mn6 Applications
Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service. Low and moderately stressed parts for vehicles, machines and engines.
28Mn6 Physical properties (average values) at ambient temperature
Modulus of elasticity [103 x N/mm2 ]: 210 Density [g/cm3 ]: 7.83
28Mn6 Soft Annealing
This will produce a maximum Brinell hardness of 223.
28Mn6 Normalizing
Normalizing temperature: 850-890o C.
28Mn6 Stress Relieving
Stress relieving to remove machining stresses should be carried out by heating to approx. 650o C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
28Mn6 Hardening
Harden from a temperature of 830-870o C followed by water or oil quenching
28Mn6 Tempering
Tempering temperature: 540-680o C
