4340 is a nickel-chromium-molybdenum alloy steel known for its toughness and its ability to attain high strengths in the heat-treated condition. It has very good fatigue resistance.
AISI 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
Ideal for highly stressed parts operating under severe conditions, aircraft quality AISI 4340 steel alloy material is excellent for shafts and valves that are subject to extreme conditions. The term Aircraft Quality (or AQ steel) which all of our steel carries means it is suitable for the production of aircraft parts which are subject to magnetic particle inspection after machining.
ASTM 4340 steel is a alloy structural steel, 4340 is used for engineering structural, Used as require good toughness, high strength, as well as the important conditioning of large size, heavy machinery such as high load of axial, turbine shaft, larger than 250 mm in diameter of helicopter rotor shaft, turbojet engine turbine shaft, blade, high load of transmission parts, fasteners of the crankshaft.
Alloy 4340 plate is another general purpose grade of steel used for industrial and machining applications. The inclusion of Nickel in Alloy 4340 helps simplify heat treatment. In addition, the Nickel in Alloy 4340 increases hardenability of the steel.
AISI 4340 Alloy Steel is a heat treatable and low alloy steel containing chromium, nickel and molybdenum. It has high toughness and strength in the heat treated condition. It is mainly used in power transmission gears and shafts, aircraft landing gear, and other structural parts.
40HNMA, 40NiCrMo7, AISI 4340 - Destination and specification Structural alloy steel with very good strength properties and particularly high hardening properties, used for thermal improvement on highly stressed machine parts exposed to impact, twisting and vibration, where suitable impact strength is
AISI 4340 is a low alloy steel containing nominally 0.4% C, 0.8% Cr, 0.25% Mo and 1.8% Ni. Higher strength levels up to 150 KSI 0.2% PS may be achieved by suitable heat treatment. Often used in preference to AISI 4140 at the higher strength levels because of its better hardenability and improved CVN impact toughness.
EN24/ AISI 4340/ 40NiCrMo84 Alloy Steel in Rounds, Square and Flats with Test Certificate is offered by Ventura Alloy And Steels Pvt. Ltd., a leading alloy steel supplier and stockist in India and Abroad.
4340 alloy steel (also known as AISI 4340) is a low alloy steel with high toughness in an annealed state. 4340 alloy steel is characterized by its outstanding ductility, formability, and weldability rendering it an excellent metal for a variety of structural applications and components including power transmission gears and shafts, aircraft parts, and machinery. 4340 steel is mainly iron based, with nickel being the
AISI 4340 is a heat treatable, low alloy steel containing nickel, chromium, and molybdenum. The inclusion of nickel improves hardenability. Regarded industry-wide for its toughness, 4340 supplies high strength in the heat treated condition while still maintaining excellent fatigue strength over time.
Example AISI/SAE No. 4340 the first two digits indicates a Nickel-Chromium-Molybdenum alloy steel the last two digits indicates carbon content roughly 0.4 percent
AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 – 1080 Mpa.
Leoscor Alloys is a known stockist and manufacturer of AISI 4340 Round Bars, which has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition.
