N/A This grade is used to advantage in applications where good machinability combined with higher strength is required, such as axles, studs, bolts, shafts, tie rods, etc.

N/A The following values are average for 1" round and may be considered as representative:
As Rolled
Tensile Strength - 95.000 psi
Yield Point - 56,000 psi
Elongation in 2" - 25%
Reduction of Area - 50%
Brinell Hardness - 197

Normalized
Tensile Strength - 97.000 psi
Yield Point - 58,000 psi
Elongation in 2" - 23%
Reduction of Area - 49%
Brinell Hardness - 201
Izod Impact - 45 Ft./Lbs.

Annealed
Tensile Strength - 85.000 psi
Yield Point - 50,000 psi
Elongation in 2" - 26%
Reduction of Area - 53%
Brinell Hardness - 174
Izod Impact - 35 Ft./Lbs.

N/A 1141 has a machinability rating of approximately 70%, based on 1212 as 100%. Average surface cutting speed is 115 feet per minute.

N/A This grade is not readily welded due to high carbon, manganese, and sulphur content. Gas or arc welding may be performed, provided area to be welded is preheated. Stress relieving after welding is recommended.

N/A Heat to 2100°-2200°F.

N/A Heat to 1600°-1700°F. Cool in air.

N/A Heat to 1400°-1500°F. Cool in furnace.

N/A This grade is essentially an oil-hardening steel. It can be water quenched, but great care should be exercised when this is done. Oil quenching temperature is between 1475° and 1550°F. A wide range of mechanical properties may be obtained by tempering at temperatures between 400° and 1200°F.
