Grade Summary: Oil-hardening chromium-molybdenum steel has good strength and wear resistance, excellent toughness and ductility with the ability to resist stress and creep at prolonged high temperatures (up to 1000)Also available in leaded grades that have greatly improved machinability, but should not be used in applications over elevated temperatures cause lower ductility in leaded grades.
Typical Applications: Drill collars, high temperature bolts, sprockets, kelly bars, reamer bodies, rotary table shafting, oil well tool joints, spindles, stay bolts, tractor axles, tractor arms, axle shafts, valves, bolts, subs, couplings, trailer axles, winch shafts, piston rods, rams, hydraulic machinery shafts, precision lead screws, chain links, zinc die-casting dies.
Available Products: Round Bar, Rectangular Bar, Square Bar, Round Tube (Hollow Bar)and Plate.
Grade Summary: This steel can obtain much deeper harden-ability than 4100 series steel. High strength in heavy sections is possible with maximum toughness and ductility. This material has a high fatigue/tensile ratio and maintains strength, ductility, and toughness at relatively high temperatures. Also has excellent non-distorting properties for an alloy steel.
Typical Applications: Crank shafts, axle shafts, dies, subs, gear shafts, gears, mine drilling parts, oil well fishing tools and parts, etc.
Available products: Round Bar and Plate.
Grade Summary: High carbon, chromium-vanadium, commercial quality alloy steel with higher strength and hardness. When heat treated, the material has excellent toughness, shock resistance, and water/abrasion resistance.
Typical Applications: Gears, pinions, shafting, axles, machinery parts, springs, heavy duty pins, bolting, hand tools.
Available products: Round Bar and Plate.
Grade Summary: Nickel imparts good toughness and ductility, chromium and molybdenum contribute increased hardness penetration and wear. They are readily carburized and the well-balanced alloy content permits hardening to produce a strong, tough core and high case hardness.
Typical Applications: Because of the fine combination of properties that may be developed, as well as the ease with which it may be processed, this material is ideal for a wide variety of applications. Gears, pinions, oil pump piston rods and liners, spline shafts, piston pins, cams, jigs, plastic molds, oil tool slips, jaws, gauges,etc.
Available products: Round Bar and Plate.
