Alloy steel 4130 is a low alloy steel that contains chromium and molybdenum as alloying elements. It has a relatively low carbon content of around 0.28-0.33%, which makes it a good choice for applications that require strength and durability. The addition of chromium and molybdenum to the alloy helps to improve its overall toughness and hardenability, making it highly resistant to wear and tear. It is often used in the construction of aircrafts and automotive parts, as well as in the production of oil and gas exploration equipment.
