4140 Tool Steel Grade Shapes, Sizes, and Technical Information From Tool Steel Service Inc. AISI 4140 is an alloy steel that is supplied in either annealed or prehardened condition. The alloy steel is composed of chromium, molybdenum, manganese containing low alloy steel. AISI 4140 Chrome-Molybdenum High Tensile Steel

  • IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingNitridingTemperingFlame and Induction HardeningAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.The AISI 4140 cold finished annealed chromium-molybdenun alloy sAISI 4140 Alloy Steel (UNS G41400)AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature.

Hardness of Heat Treated 4140 - Metal and Metallurgy The maximum hardness that can be obtained in any steel depends on carbon content. The section size in which maximum hardness can be obtained depends on alloy content. 4140 has a nominal carbon content of .4% and this carbon content will yield a hardness of Rc 51 for a 90% martensitic structure (9th Edition of the ASM Material Handbook,Volume I). Materials - Steel - Carbon, Alloy, Grades G.L. HuyettMax. attainable Rockwell hardness is B97. Melting point is 2750° F. Yield strength is 95,000 psi. 4140 Alloy Also called chrome-moly steel. Ideal for forging and heat treating, 4140 alloy is tough, ductile, and wear resistant. Max. attainable Rockwell hardness is C20-C25. Melting point is 2750° F. Yield strength is 60,000-105,000 psi.
