4130 Chromoly Steel

Chromoly 4130 is a low alloy steel containing chromium molybdenum iron carbon and other alloying elements.

4130 chromoly steel.

The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness. 4130 alloy steel tubing is cold drawn and seamless. Alloying elements include chromium and molybdenum and as a result these materials are often informally referred to as chromoly steel common variant stylings include chrome moly cro moly crmo crmo cr moly and similar they have an excellent strength to weight ratio and are considerably. The 30 at the end of the grade number designates that it has approximately 0 30 carbon by weight.
