Medium Carbon Steel Seamless Tube Widely Used S40C In Mechanical Purpose

 

CHARACTERISTICS

 

It is a steel equivalent to medium carbon steel and is a material equivalent to semi-hard steel to hard steel. When it comes to the amount of carbon around this range, the strength of the carbon steel will also come out by heat treatment. Hardness and stickiness are often proportional to half. The final specifications of steel materials are determined by both the components that are born and the heat treatment that is growing up.
