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 Material DatasheetAISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for providing a good balance between strength and malleability. Alloy 4340 is composed of (descending in order by weight):iron, nickel, chromium, manganese, carbon, molybdenum, silicon, phosphorus and sulfur. With proper working and strengthening, items made from 4340 have excellent wear and durability qualities.
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.
AISI 4340 Steel - Delivered Nationwide by West Yorkshire AISI 4340 is a nickel chromium molybdenum alloy steel specification widely used in the oil and gas sectors. As a quality grade alloy steel it offers toughness and high strength in the heat treated condition, with good fatigue strength.
AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun Steel4340 Steel Heat Treatment. 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 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. Pre hardened and tempered 4340 steels can be further surface hardened by
