4140 Alloy Structural Steel Rod High Temprature Resistance
Size Customizable Aisi 431 Stainless Steel Round Bar Price Per Kg
|
4140 steel is an alloy structural steel with high strength, hardenability, good toughness and small deformation during quenching.It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded. |
