N/A A general purpose alloy machinery steel used where greater strength and toughness is reguired than is available in many carbon machinery steels. Typical applications include gears, shafts, pinions, spindles, arbors, bolting, link pins, axles, etc.

N/A The following mechanical properties are typical in the heat treated condition:
1"Round
Tensile Strength - 136.000 psi
Yield Strength - 119,000 psi
Elongation in 2" - 20.5%
Reduction of Area 55.0%
Brinell Hardness 285

5"Round
Tensile Strength - 137.000 psi
Yield Strength - 116,000 psi
Elongation in 2" - 17.0%
Reduction of Area 50.0%
Brinell Hardness 293

N/A 4150 Modified Resulphurized machines approximately 40% as fast as 1212 Screw Stock. Average surface cutting speed is 65 feet per minute.

N/A Difficult to weld because it is resulphurized and has definite air-hardening characteristics, but can be welded by any of the standard welding methods. Shielded arc welding, low hydrogen electrodes, pre-heating and post-heating is preferred and recommended

N/A Temperatures and response is similar to those of 4142-4150.
