4140 is a 1% chromium – molybdenum medium harden capacity broadly useful in high tensile steel – for the most part supplied are hardened and tempered in the malleable scope of 850 – 1000 Mpa (condition T).4140 is presently accessible with enhanced mach inability, which greatly increases feeds and/or speeds, while also extending tool life without adversely affecting mechanical properties.

4140 is utilized broadly as a part of most industry areas for an extensive variety of utilizations, for example, Adapters, Arbors, Axle Shafts, Bolts, Crankshafts, Connection Rods, Chuck Bodies, Collets, Conveyor Pins & Rolls, Ejector Pins, Forks, Gears, Guide Rods, Hydraulic Shafts & Parts, Lathe Spindles, Logging Parts, Milling Spindles, Motor Shafts, Nuts, Pinch Bars, Pins Various, Pinions, Pump Shafts, Rams, Sockets, Spindles, Sprockets, Studs, Tool Holders, Torsion Bars, Worms etc.
