N/A Carbon .37.45
Manganese 1.35/1.65
Phosphorus .04 Max.
Sulphur .08/.13 Max.

N/A These grades, because of their free machining properties, are usually processed in automatic screw machines. They are recommended for studs, axles, pins, bolts, and various machinery parts requiring considerable machining, close finish tolerances, bright finish, and high mechanical properties.

N/A The following values are average for 1" round, and may be considered as representative of these grades:
Tensile Strength - 100,000 psi
Yield Strength - 90,000 psi
Elongation in 2" - 10%
Reduction of Area - 30%
Brinell Hardness - 197

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

N/A These grades are not readily welded due to the higher carbon and sulphur content. Gas or arc welding may be used providing joints are preheated. To develop equivalent strength in a weld, a low alloy filler is recommended. Stress relieving after welding is also recommended. The grade of welding rod to be used depends on the thickness of section, design, service requirements, etc.

N/A Although primarily oil hardening steels, these grades can be water quenched, but great care should be exercised when this is done. The quenching temperature is 1500°-1600°F, with the temperature being 25°F lower for water quench. Temper to required hardness.
