4140 Alloy Steel Bar Stock

The 4140 alloy steel is widely used across numerous industries and is considered to be an excellent material choice due to its physical and structural toughness.

4140 Alloy Steel Round Bar Stock

Industries get hold of a 4140 alloy steel bar stock simply because of its high-fatigue strength, toughness, impact, and abrasion resistance.

The 4140 alloy steel has such types of characteristics because of its chemical components of chromium, molybdenum, and manganese.

The addition of chromium and molybdenum promotes an excellent resistance to corrosion while manganese helps in increasing its hardenability as well as its machinability.

With these excellent chemical components within the 4140 alloy steel, it’s understandable why a lot of industries acquire stocks for their various applications.
