Alloy Steel 4340 Alloy Steel 4340, also referred to as AISI 4340, is a nickel, chromium, and molybdenum alloy steel. This heat treatable alloy is known for its toughness and high strength in a heat treated condition. It is weldable by both fusion and resistance welding, and offers good ductility in the annealed condition.
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.
AISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. Flame or Induction Hardening As mentioned above, pre hardened and tempered 4340 steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.
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.
ASTM A36 Carbon Steel vs. Normalized SAE AISI 4340 Both ASTM A36 carbon steel and normalized SAE AISI 4340 are iron alloys. They have a very high 96% of their average alloy composition in common. For each property being compared, the top bar is ASTM A36 carbon steel and the bottom bar is normalized SAE AISI 4340.

4340 steel is a low alloy steel that contains Nickel, Chromium and Molybdenum as strengthening agents. 4340 can also be hardened through heat treatment. Flame and induction hardening is the type of heat treatment that works with 4340. 4340 offers better hardenability and improved impact toughness over 4140. Alloy 4340 can obtain deep hardenability.

AISI 4340 is a low alloy steel containing nominally 0.4% C, 0.8% Cr, 0.25% obtain the specified mechanical properties after heat treatment) must always be 4130 vs 4340 Steel Comparison Capital Steel & Wire 4130 and 4340 are both popular steel grades at Capital Steel & Wire.
Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness. The concentration of alloy element of this kind of steel is quite high, mainly are corrosion resistant steel, heat resistant steel, wear resistant steel, and other special steels of physical and chemical properties.
Sep 03, 2018 · AISI 4340 alloy steel is mainly used in power transmission gears and shafts, aircraft landing gear, and other structural parts. From an old metallurgical engineer and steelmaker.
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
