Q+T Alloy Metal Spherical Bar one.7225/SAE4140 For CZPT
AISI 4140 Steel Bar, Metal Plate, Flats Supplier, Stockist and Exporter. AISI SAE 4140 alloy metal is a chromium molybdenum alloy steel specification widely utilised in general objective substantial tensile metal for parts, like axles, shafts, bolts, gears and other applications. Similar to alloy quality AISI 4130 chrome moly alloy metal but with a somewhat increased carbon content material. The higher carbon content of AISI 4140 metal gives better energy and heat remedy capabilities in comparison to AISI / ASTM 4130 alloy steels, even so it does have inferior weldability qualities.

Preheat the steel cautiously, warmth to 1150 oC – 1200 oC optimum, hold until temperature is uniform through the segment.
Do not forge beneath 850 oC.Following forging operation the operate piece need to be cooled as slowly and gradually as attainable.
Heat ASTM 4140 steels to 800 oC – 850 oC, maintain right up until temperature is uniform all through the segment and great in furnace.
Heat steel alloy 4140 to 870 oC – 900 oC, maintain until temperature is uniform all through the section, soak for ten – 15 minutes and great in nevertheless air.
Re-warmth 4140 grade metal to 550 oC – 700 oC as essential, hold until temperature is uniform all through the part, soak for 1 hour per 25 mm of part, and amazing in still air.
AISI alloy 4140 metal bar, plate and sq. can be hardened by cold operating, or heating and quenching.
SAE 4140 alloy metal is generally equipped ready heat treated to hardness in eighteen-22 HRC. If more heat remedy is necessary, then heat to 840 oC – 875 oC, hold right up until temperature is uniform during the section, soak for ten – 15 minutes per twenty five mm segment, and quench in oil, water, or polymer as necessary.
ASTM alloy 4140 metal bar, flat or plate materials can be employed for as extensive variety of apps exactly where increased toughness and wear resistance is essential more than reduce carbon grades. Standard apps for 4140 tool steel uses contain Factors, Adapters, Arbors,strippers, holder blocks, mould bases, ejectors, back again 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, equipment racks, chain back links, spindles, device bodies, device holders, tie rods, Link Rods, Chuck Bodies, Collets, CZPT Pins & Rolls, Ejector Pins, Forks, Gears, Xihu (West Lake) Dis.
