5 Facts About Manganese in Steel | Speaking of Precision Blog

Manganese is a chemical element that is present in all commercial steels, and contributes substantially to a steel's strength and hardness, but to a lesser extent than does carbon. The effectiveness of Manganese in increasing mechanical properties depends on and is proportional to the carbon content of the steel.
