SCM440 42CrMo4 4140 hot forged rolled steel round bar

SCM440, 42CrMo4, and 4140 are all designations for a type of hot forged rolled steel round bar. Here's what you need to know about them:

1. SCM440: This is a Japanese grade designation for a chromium-molybdenum alloy steel with a carbon content of around 0.38-0.43%. It is known for its high strength, toughness, and hardenability.

2. 42CrMo4: This is a European standard (EN) designation for the same steel grade as SCM440. The number "42" indicates the average carbon content (0.42%) and "CrMo4" refers to the chromium and molybdenum alloying elements present in the steel.

3. 4140: This is an American standard (AISI/SAE) designation for the same steel grade as SCM440 and 42CrMo4. It is widely used in various industries due to its excellent combination of strength, toughness, and wear resistance.

These steel grades are commonly utilized in applications such as axles, gears, shafts, and machine components where high strength and good fatigue resistance are required. The hot forged rolled process enhances the mechanical properties of the steel, resulting in improved strength and superior metallurgical characteristics.
