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.
4340- Highly alloyed steel, nominally 1.8% Ni, .80% chromium and .25% molybdenum. High strength characteristics. Used for heavily stressed parts operating in fatigueand other duty conditions. AISI 4340 has a favorable response to heat treatmentusually oil quenchingfollowed by temperingand exhibits a good combination of ductilityand 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.
