Carbon Steel Flanges Manufacture and Exporter

As compared to stainless steel grades, the carbon steel pipe flanges have a higher carbon content. This high content of carbon is what gives the carbon steel plate flanges a lower melting point. An increased carbon content in the cs slip on flanges makes them more malleable. Further, these flanges have good durability and they offer better heat distribution properties.
