AISI 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. 4340 Steel 36CrNiMo4 1.6511 EN24 SNCM439 - Otai AISI 4340 steel is a medium carbon, low alloy steel. Otai steel is one leading supplier of 4340 steel & equivalents:36CrNiMo4, 1.6511, EN24, SNCM439 etc.
