Molybdenum medium harden capability fundamental cause excessive tensile metal. It is pre-hardened and tempered and can be additional surface hardened by flame or induction hardening and by means of nitriding.

STEEL PROPERTIES:-

•  AISI 4140 alloy steel is a 1% chromium- molybdenum medium hardenability.
• High tensile steel is generally provide hardened and tempered in the tensile range of 850-1000 Mpa (condition).
• 4140 steel is currently out there with improved machinability.
• Greatly increases feeds or speeds. • Extending tool life by not adversely affecting mechanical properties.

APPLICATION:-

ASTM alloy 4140 steel bar, flat or plate material can be utilized for as wide variety of applications where greater toughness and wear resistance is required over lower carbon grades. The applications of 4140 steel includes components, adapters, strippers, holder blocks, mould bases, ejectors, backup and support tooling, fixtures, jigs, moulds, cams, drill collars, axle shafts, bolts, crank shafts, 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 and rolls, ejector pins, forks, gears, guide rods, hydraulic shafts and 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.
