Process OF Alloy steel bar AISI/SAE
4140 : EAF+LF+VD+FORGE
Leading Futures OF Alloy steel bar AISI/SAE4140 : Compared with 35CrMo, the
4140 has higher intensity and better hardenability for that
4140 bears more carbon and chromium. The fatigue strength and impact resistance of
4140 are promoted after tempering. The low temperature impact toughness is great and there is no temper brittleness. This kind of material is usually used after being tempered.
Application of OF Alloy steel bar AISI/SAE4140 : Alloy steel bar AISI/SAE4140 is often applied for making important machinery parts, such as bearing, gear, connecting rod, transmission gear, supercharger gear, engine cylinder, spring, 1200mm~2000mm rotary shouldered connections for petroleum industry, jar knocker, substitute of hardened and tempered steel with higher chromium composition, which demand higher strength and larger size than 35CrMo.
