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.


Detailed

4340 steel offers toughness and high strength in the heat treated condition, with good fatigue strength. Available in round bar 4340 is . available fully certified and suitable for applications requiring a quality high tensile alloy steel. AISI 4340 is commonly supplied quenched . and tempered with a hardness of between 24 to 29HRc. 8. Applications


Detailed

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. An additional grade of Alloy 4340 is Alloy E 4340.


Detailed

Low alloy vacuum melted steel of very high strength. It is a modified AISI 4340 with silicon, vanadium and slightly highercarbon and molybdenum content than 4340. See the Datasheet here >


Detailed

AISI 4340 Steel has high strength, toughness and good hardenability and stability against overheating. It needs to be preheated before high temperature after welding. It needs to be relieved after welding and used after quenching and tempering.4340 can be used to make important parts of special performance requirements after nitriding treatment.

AISI 4140 Steel Bar, Steel Plate, Flats Supplier, Stockist and Exporter. AISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications.Similar to alloy grade AISI 4130 chrome moly alloy steel but with a slightly higher carbon content.


Detailed

Relatively high carbon, high alloy steels like American Iron and Steel Institute (AISI) 4130 must be heat treated before they can be machined or formed. Two processes change the hardness of 4130, annealing and normalizing, both of which may be applied depending on the desired application of the steel.
