Available Grades of Steel Alloys

Hot Rolled Steel Bars
Grade Description
ASTM A36 Low carbon, general purpose for structural applications. Minimum physical properties of 36,000 psi yield strength and 58,000 psi tensile strength.
HR Bars 1117 Low carbon high manganese steel. Used in manufacturing parts requiring considerable machining and close tolerances along with a smooth finish. Especially suitable for carburized parts requiring a soft core and high surface hardness. Used for gears, pinions, pins and ratchets.
HR Bars 11L17 1117 with the addition of .15% to .35% lead providing improved machinability without changing the excellent case hardening characteristics of 1117.
HR Bars 1045 Medium carbon steel used when greater strength and hardness is desired. Can be hammer forged and responds to heat treatment: Suitable for flame and induction hardening. Used in gears, shafts, axles, bolts, studs, and machine parts.
HR Bars 1141 Medium carbon, special quality, manganese steel with improved machinability and a deeper, uniformed heat treatment response than plain carbon steel.
Cold Rolled Steel Bars
CR Bars 1018 Low carbon, medium manganese content. Good hardening properties, fair machinability. Readily brazed and welded.
CR Bars 12L14 Lead bearing steel with extraordinarily fast machining speeds. Widely used in screw machining work. Hass excellent ductility and fine surface quality.
Alloy Bars
Alloy Bars 4140 A through hardening chromium molybdenum carbon steel not subject to temper embrittlement. It is recommended for heavy duty service. 4140 has high hardenability, good fatigue, abrasion, and impact resistance. It can be successfully nitrided for maximum wear and abrasion resistance. It is deep hardening suitable for severe service characterized by fatigue, abrasion, impact, high temperature stresses or combination of such stresses in both small and large sections.
Alloy Bars 4340 A tough, chock resisting, oil hardening nickel-chromium-molybdenum steel. In the heat treated condition, it is the highest combination of tensile and endurance strengths along with ductility. Maintains good strength properties at elevated temperatures. The high depth hardness is reflected in excellent torque properties. Recommended for heavy duty, high strength applications.
Alloy Bars 8620 Most widely used case hardening alloy steel, with high core strength and toughness.
