This section will discuss the similarities of the two variants of the 41xx series to know how to use them and select the right one for your project. Below are the similarities between the two variants.
· Element Composition
Both 4140 and 4130 steel have the same elemental composition, with common elements being carbon, molybdenum, chromium. However, they differ in terms of their carbon content.
· Anti-Rust Property
Both steel variants do not have anti-rust properties. While it has chromium similar to stainless steel, it is not enough to grant it the anti-rust properties desired. Consequently, the two variants undergo heat treatments for more stability.
· Heat Treatment
To make them stronger, both variants are subjected to heat treatment such as annealing, cold working, etc. This leads to an increase in tensile strength, ductility, hardness, etc. Therefore, they are more machinable and easily fabricated.
