Description

41L40 Steel Cold Drawn Round Bar Stock - 1.25" Diameter x 6" Length
Alloy Steel 41L40
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:
