Description

4140 High Tensile Steel

4140 is a 1% chromium Рmolybdenum medium hardenability general purpose high tensile steel Рgenerally  supplied hardened and tempered in the tensile range of 850 Р1000 Mpa (condition T). 4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties. Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nitriding. 4140 is used extensively in most industry sectors for a wide range of applications such as: 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..
