4340 (E4340) Alloy Steel, AISI 4340, Plate, Round Bar AQ

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.

Effect of austempering conditions on the microstructure

Nov 01, 2019 · In comparison with the AISI 4140 steel, AISI 4340 has been showed to possess much better combination of hardness and impact strength in the austempered state. As indicated in the Table 1, carbon content is same in both steels; however, nickel is only present in AISI 4340 steel. Addition of nickel has been previously reported to adversely affect Rickard Metals 4340 Alloy Steel4340 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
