Materials | Carbon and low alloy steels

Carbon steels are those with no deliberate alloy additions. They are mainly used in general engineering, constructional and pressure applications.

Low alloy steels have superior mechanical properties in comparison to plain carbon steels due to their additional alloying elements such as chromium, molybdenum and nickel. Furthermore, suitable alloy content will provide improved wear and corrosion resistance.
