Carbon Steel Welding Neck Flange is the most commonly used in carbon steel flange, is divided into two kinds of casting and forging process of.On the mechanical properties of the forging flange is higher than the casting flange, forging flange structure more uniform, the density is higher, more complete structure, higher strength.

　　The material of Q235 carbon steel is a kind of steel.Q represents this kind of material yield, behind the 235, is refers to the material yield value, at around 235.And with the increase of the thickness of the material and reduce the yield value.
