General Characteristics of 4130

4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. It offers a great mix of strength and toughness. The machinability and weldability of 4130 is good. The alloy may be welded using any commercial method. The material may require a post-weld stress relief heat treatment in certain instances.


What is the main difference Normalized and Annealed?

Normalized material has a higher tensile strength than Annealed material. So because of this Annealed will be easier to form than Normalized.
