Carbon Steel flange rubber expansion joint

Carbon steel is iron-carbon alloy containing less than 2.11% carbon content Wc.In addition to carbon, carbon steel also contains small amounts of silicon, manganese,sulfur,phosphorus.Common carbon steel’s carbon content is generally less than 1.3%.Its strength, toughness and performance are better.
Carbon steel is cheap and easy to smelt and process.In general it can meet the performance requirements,so it is the most widely used engineering metals.

Our main material of flange is carbon steel Q235,Q345,A106,20#,35#.
