Alloy Steel Round Bar 1.7225/SAE4140 For Machinery Q+T

Product Introduction
AISI 4140 Metal Bar, Metal Plate, Flats Provider, Stockist and Exporter. AISI SAE 4140 alloy steel is a chromium molybdenum alloy metal specification widely employed in standard goal high tensile steel for elements, like axles, shafts, bolts, gears and other purposes. Comparable to alloy quality AISI 4130 chrome moly alloy steel but with a slightly larger carbon content material. The larger carbon content material of AISI 4140 metal offers better energy and heat therapy abilities in comparison to AISI / ASTM 4130 alloy steels, however it does have inferior weldability traits.

Preheat the steel meticulously, heat to 1150 oC – 1200 oC optimum, keep right up until temperature is uniform all through the section.
Do not forge underneath 850 oC.Adhering to forging procedure the perform piece must be cooled as slowly as feasible.

 Heat Therapy

  • Annealing
    Heat ASTM 4140 steels to 800 oC – 850 oC, hold till temperature is uniform throughout the segment and awesome in furnace.
  • Normalizing
    Heat steel alloy 4140 to 870 oC – 900 oC, keep until temperature is uniform all through the segment, soak for ten – 15 minutes and great in even now air.
  • Tempering
    Re-heat 4140 quality steel to 550 oC – 700 oC as needed, hold right up until temperature is uniform during the section, soak for one hour per twenty five mm of segment, and cool in even now air.


AISI alloy 4140 metal bar, plate and square can be hardened by chilly operating, or heating and quenching.
SAE 4140 alloy metal is generally supplied ready heat treated to hardness in eighteen-22 HRC. If further heat remedy is necessary, then warmth to 840 oC – 875 oC, maintain right up until temperature is uniform throughout the area, soak for ten – fifteen minutes for each 25 mm part, and quench in oil, h2o, or polymer as required.


ASTM alloy 4140 steel bar, flat or plate materials can be utilized for as extensive assortment of programs the place higher toughness and use resistance is needed in excess of lower carbon grades. Common apps for 4140 tool steel uses include Components, Adapters, Arbors,strippers, holder blocks, mildew bases, ejectors, back up and help 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, equipment racks, chain links, spindles, tool bodies, resource holders, tie rods, Relationship Rods, Chuck Bodies, Collets, Conveyor Pins & Rolls, Ejector Pins, Forks, Gears, Xihu (West Lake) Dis.
