Aircraft quality 4130 alloy steel is a medium carbon, low alloy steel containing 0.15/0.25% molybdenum and 0.80/1.10% chromium as strengthening agents. This type of steel is also commonly referred to as a chromoly steel, or chrome moly steel. Due to its relatively low carbon content of 0.28/0.33%. These 4130 steel properties offer exceptional weldability. With the proper heat treatment it is also readily machined. Annealing 4130 (E4130) alloy steel offers excellent ductility. 4130 steel can also be normalized or otherwise heat treated. Steel 4130 (E4130) has an excellent strength to weight ratio and is considerably stronger and harder than other standard grades of steel. Chromoly steels are especially useful in their ability to retain their bulk properties while allowing for significant hardness to be attained.
It is an exceptional welding steel, being weldable in all commercial methods, and is readily machined in its normalized/tempered condition. 4130 steel is easily cold worked, hot worked, and forged, but cannot be aged. It has excellent ductility when annealed and is a through-hardening alloy.
4130 steel is an alloy made up of chromium and molybdenum. It has a higher strength-to-weight ratio than mild steel, making it ideal for projects where weight is a significant factor, such as automotive parts or aircraft components. It also has superior corrosion resistance and can tolerate very high temperatures without losing its shape or integrity. However, because it’s much harder than mild steel, it can be difficult to cut or form into shapes without special tools and equipment.
