4340 High Tensile Steel Interlloy Engineering Steels

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.

J404:Chemical Compositions of SAE Alloy Steels - SAE

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.

The Mechanical Threshold Stress model for various

of AISI 4340 steel using experimental data gleaned from the open literature. We compare stress-strain curves and Taylor impact test proles predicted by the Mechanical Thresh-old Stress model with those from the Johnson-Cook model for 4340 steel. In addition, temperature- and pressure-dependent shear modulus models, melting temperature models,Datasheet for Steel Grades Carbon Steel AISI 4340This page is mainly introduced the AISI 4340 Datasheet, including chemical information,mechanical properties, physical properties, mechanical properties, heat treatment, and Micro structure, etc. It also contains the use of AISI 4340,such as it is commonly used in bars, sheet,plates, steel coils, steel pipes,forged and other materials application.
