The hardenability of a metal alloy is the depth to which a material is hardened after putting it through a heat treatment process. The unit of hardenability is length. It is an indication of how deep into the material a certain hardness can be achieved.

Alloy 4130 is a chrome moly alloy. It is very popular for welding applications and is often used in the normalized condition without further heat treatment. It can be nitrided to enhance its wear quality. Its popularity is primarily due to its weldability, hardenability, and machinability. Alloy 4130 contains similar properties as Alloy 8630.

SAE AISI 4130 (SCM430, G41300) Cr Mo Steel :

Among alloy steels, the composition of SAE AISI 4130 steel is notable for containing comparatively high amounts of chromium (Cr) and manganese (Mn). Chromium is used to improve corrosion resistance and most mechanical properties (particularly at higher temperatures). Manganese is used to improve hardenability, hot workability, and surface quality.
