Description
This is a higher carbon variation of the chromium, manganese, molybdenum 4100 series of low steel/" target="_blank" class="keylink">alloy steels.

Applications
Statically and dynamically stressed components for vehicles, engines and machines, for parts of larger cross-sections. Components for driving gears, axles, rolls, rings.

Physical properties (avarage values) at ambient temperature
Modulus of elasticity [10³ x N/mm²]: 190-210
Density [g/cm³]: 7.84

Continuous Cooling Transformation (CCT) Diagram

Time-Temperature Transformation (TTT) Diagram

Soft Annealing
Heat to 680-720^oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 248.

Hardening
Hardening: 820-850, 830-860^oC, water, oil.

Normalizing
Normalizing: 840-860^oC

Tempering
Tempering temperature: 540-680^oC

Hardness after heat treatmnet
Aannealed at 815^oC: 197 HB
Normalized at 870^oC: 321 HB
Oil quenched, fine grained, tempered at 205^oC: 530 HB
Oil quenched, fine grained, tempered at 315^oC: 495 HB
Oil quenched, fine grained, tempered at 425^oC: 440 HB
Oil quenched, fine grained, tempered at 540^oC: 370 HB
Oil quenched, fine grained, tempered at 650^oC: 290 HB

Diagram Tempering Temperature - Mechanical Properties

Forging
Hot forming temperature: 1050-850^oC.

Machinability
Machinability of 4150 is good in the annealed condition, or in the normalized condition. After heat treatment the alloy can be very hard and it is best to limit machining at that point to grinding.

Corrosion Resistance
This is not a corrosion resistant alloy. Use protective coating.

Welding
The alloy may be welded by conventional methods. Welding the alloy in the hardened (heat treated) condition may affect the mechanical properties due to welding heat input. A post-weld heat treatment may be needed. Follow an approved weld procedure.
