AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 steel from stock.
4340 alloy steel bar is used heavily in the aerospace industry due to its ultra-high strength. When heat treated it is known for its toughness while preserving good fatigue strength. For highly stressed parts it is excellent choice. It can be machined by all customary methods. This material is available in both vacuum melt (VM) and air melt (AM). 4340 Heat Treated - pmtsco4340 Heat Treated HOT ROLLED & COLD FINISHED. PACIFIC 4340 is available in two conditions:heat treated (quenched and tempered) to high strength or annealed for ease of machining and subsequent heat treatment. It is a nickel-chromium-molybdenum medium carbon alloy steel with deep hardenability. It can be through hardened in large sections.
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. Pre hardened and tempered 4340 can be further surface hardened by flame or 4340 Steel 36CrNiMo4 1.6511 EN24 SNCM439 - Otai AISI 4340 steel is a medium carbon, low alloy steel. Otai steel is one leading supplier of 4340 steel & equivalents:36CrNiMo4, 1.6511, EN24, SNCM439 etc.
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. Datasheet for Steel Grades Carbon Steel AISI 4340This page is mainly introduced the AISI 4340 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of AISI 4340,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
AISI 4340 HT Steel. AISI 4340 alloy steel is a medium carbon nickel-chromium molybdenum alloy steel that creates an excellent combination of ductility, toughness, and strength after heat treating. It has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. It is often utilized where other alloy
