4340 High Tensile Steel. 4340 is a 1.8% nickel - chromium - molybdenum high hardenability high tensile steel - generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa (condition U) - (Rc 28 - 36).. Characterised by high strength and toughness in relatively large sections. Pre hardened and tempered 4340 can be further 4340 Steel 36CrNiMo4 1.6511 EN24 SNCM439 - Otai AISI 4340 steel is a medium carbon, low alloy steel.

Feb 01, 1991 · Chemical Compositions of SAE Alloy Steels. J404_200901. In 1941, the SAE Iron and Steel Division in collaboration with the American Iron and Steel Institute (AISI) made a major change in the method of eing composition ranges for the SAE steels. The plan, as now applied, is based in general on narrower ladle analysis ranges plus certain K ELEVATED TEMPERATURE FATIGUE PROPERTIES OF ELEVATED TEMPERATURE FATIGUE PROPERTIES OF SAE 4340 STEEL W.
