Description 4340 is a heat treatable, low alloy steel containing nickel, chromium and molybdenum. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength. Commercial Quality available along with Air Craft Quality (Vac. Melt) 4340 Alloy Steel Available Now at NeoNickelAbout 4340 Alloy Steel. 4340 Alloy Steel is an iron-based alloy containing nickel, chromium and molybdenum. The relatively high carbon content provides this alloy with superior strength in applications where severe service conditions exist. 4340 Alloy Steel
4340 is a 1.8% nickel - chromium - molybdenum high hardenability high tensile steel - generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa (condition U) - (Rc 28 - 36).. Characterised by high strength and toughness in relatively large sections. 4340 Round Steel Bar Supplier Eaton Steel Bar CompanyHot rolled 4340 steel bar is a nickel-chromium-molybdenum medium carbon alloy steel that is known for its toughness. This steel grade also has good ductility and high strength. Hot rolled 4340 bar has good impact, and wear resistance in the hardened condition. AISI SAE 4340 30CrNiMo8 DIN 1.6580 Hot Forged Alloy Steel 4340 steel is a nickel chromium molybdenum high hardenability high tensile steel, generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa (condition U) - (Rc 28 - 36). Characterised by high strength and toughness in relatively large sections. Pre hardened and tempered 4340 can be further surface hardened by flame or induction hardening and by nitriding.
AISI/SAE 4340 Alloy Steel, 4340, is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition. Commercial and military aircraft, automotive systems, forged hydraulic and other machine tool applications, forged steel crankshafts. Alloy Steel McMaster-CarrAlso known as chrome-moly steel, 4140 alloy steel resists fracturing from repeated stress. Multipurpose 4140 Alloy Steel Bars Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders.
