General Characteristics of 4130
4130 grade is a low-alloy steel that incorporates chromium and molybdenum as agents to enhance strength. It presents an excellent balance of strength and toughness. Additionally, 4130 exhibits favorable machinability and weldability, allowing for welding using various commercial methods. In specific cases, the material may necessitate a post-weld stress relief heat treatment.

What is the main difference Normalized and Annealed?
Annealed material is easier to form compared to normalized material due to its lower tensile strength.
