Forging

Preheat the steel carefully, heat to 1150 oC – 1200 oC maximum, hold until temperature is uniform throughout the section.
Do not forge below 850 oC.Following forging operation the work piece should be cooled as slowly as possible.

AISI 4140 Steel Grade Heat Treatment

Annealing
Heat ASTM 4140 steels to 800 oC – 850 oC, hold until temperature is uniform throughout the section and cool in furnace.

Normalizing
Heat steel alloy 4140 to 870 oC – 900 oC, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes and cool in still air.

Tempering
Re-heat 4140 grade steel to 550 oC – 700 oC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air.

Hardening of AISI Alloy Steel 4140

AISI alloy 4140 steel bar, plate and square can be hardened by cold working, or heating and quenching.

SAE 4140 alloy steel is usually supplied ready heat treated to hardness in 18-22 HRC. If further heat treatment is required, then heat to 840 oC – 875 oC, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.

Application of AISI alloy round 4140 steel bar

ASTM alloy 4140 steel bar, flat or plate material can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades. Typical applications for 4140 tool steel uses include Components, Adapters, Arbors,strippers, holder blocks, mold bases, ejectors, back up and support tooling, fixtures, jigs, molds, cams, drill collars, Axle Shafts, Bolts, Crankshafts,stubs, couplings, reamer bodies, axles, shafting, piston rods, rams, hydraulic machinery shafts, gears, sprockets, gear racks, chain links, spindles, tool bodies, tool holders, tie rods, 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, Pinions, Pump Shafts,boring bars,tracks, slides, wear strips or parts, forming dies, brake dies, trim dies, bolsters, machinery parts and components, etc.
