Welding of 4340 steel in the hardened and tempered condition (as normally supplied), is not recommended and should be avoided if at all possible, as the mechanical properties will be altered within the weld heat affected zone. 4340 Alloy Steel 1.6511 36CrNiMo4 40NCD3 Forged AISI 4340 steel at 1150-1200 ºC. no forging when below 850 ºC . Heat Treatment of SAE/AISI 4340 Alloy Steel 4340 Steel Annealing Slowly heat to 8008500 ºC, keep enough time, ensure heat thoroughly. then cooling in furnace to 480 ºC, then cool in air. After annealing, the hardness 92 HBS Max. AISI 4340 Steel Hardening & Quenching
The 4340 alloy steel is a nickel-chromium molybenum with a medium carbon content. It has excellent ductility, toughness and strength characteristics that make it useful for a 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.
4340 Steel Tempering. AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering.Tempering is usually carried out to relieve stresses from the hardening process, but primarily to obtain the required hardness and mechanical properties. The actual tempering temperature will be chosen to meet the AISI 4340 Steel W-Nr. 1.6511 DIN 36CrNiMo4 - OTAI Aisi 4340 Steel is a high quality Quenched and Tempered Alloy Structural steel, Oil Quenched & Tempered Hardness is 28-34 HRc.4340 Annealing delivery hardness less than 250HB. 4340 Alloy structural steel properties is very simliar with GB 40CrNiMo steel, JIS SNCM439 and DIN 1.6511 36CrNiMo4 Alloy structural steel.

Oct 13, 2020 · Martensitic microstructure of AISI 4340 steel can be heat treated to achieve the desired mechanical properties. However, mechanical properties degrade owing to the impurities and cleanliness during the steel production. In this work, AISI 4340 steel was produced through three different routes, such as vacuum degassing (VD), electro slag remelting (ESR), and vacuum arc SUS347 good corrosion resistance Austenitic stainless steelSUS347 (347 / S34700 / 0Cr18Ni11Nb) is a steel, 347 stainless steel has excellent high temperature stress breaking (Stress Rupture) performance, and high temperature resistance to creep performance (Creep Resistance) stress mechanical properties.
