Properties of Alloy Steel
Alloy steels can contain a wide range of elements, and each one can improve the material’s ability to resist corrosion, heat, and mechanical stress. Smaller additions of up to 20 weight percent tend to boost corrosion resistance and stability at high or low temperatures, whereas smaller additions of up to 5 weight percent tend to improve mechanical qualities, such as improving hardenability and strength.
The table below summarises the impact of adding various elements to steel along with typical weight fraction levels.
