[10 3 x N/mm 2]:210 Density [g/cm 3]:7.82 Soft Annealing Machining is best done with this alloy in the annealed or 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.
4340 - Highly alloyed steel, nominally 1.8% Ni, .80% chromium and .25% molybdenum. High strength characteristics. Used for heavily stressed parts operating in fatigue and other duty conditions. AISI 4340 has a favorable response to heat treatment usually oil quenching followed by tempering and exhibits a good combination of ductility and strength when treated thusly. 4340 ALLOY In Stock Castle Metals SiteAlloy 4340 in Plate SPECIFICATIONS:AISI4340, ASTM A 829 / A6 SAE J404, AMS 2252/ 2301/6359 SAE J404 Castle Metals stocks Alloy 4340 plate through our global distribution network.
