Carbon Steel Square Tube

Product Description

We can provide following three categories carbon steel:

-Low-carbon steel with a carbon content of between 0.04% and 0.30% is the largest category of carbon steel.
Properties: High toughness; Low tensile strength; High weldability; Low cost; High ductility; Low hardness; High machinability.

-Medium carbon steel with typical carbon values between 0.31% and 0.60% and manganese content between 0.31% and 0.60%
Properties: Medium strength; Moderate toughness; Medium weldability; Medium ductility; Moderate machinability.

-High-carbon steels are often referred to as “carbon tool steels” and typically contain between 0.61% and 1.50% carbon.
Properties: High toughness; Low machinability; High strength; Moderate weldability; Low ductility.
