What is known as the carbon steel flange?

Material is called carbon steel flange carbon steel flange
Flange is the connection the two large diameter pipeline installations, usually add a number of tightening the two flange bolts. Carbon steel flange is made of carbon steel flanges. Good ductility low carbon steel low intensity after adding suitable amount of carbon will become hard, plastic lower intensity. Flange connection may need to withstand very high tensile, compressive, torsional, shear strength, carbon steel flange is the better choice.

There are corresponding to the stainless steel flange.
