20K JIS Flange Carbon steel Flange Blind Flange

Forging flange generally lower than the casting flange carbon is not easy to rust, forging good streamline, organization is compact, mechanical performance is superior to the casting flange; Improper forging technology also can appear grain big or uneven, solidification cracking phenomenon, higher than the casting flange forging cost. Forging than casting can withstand the higher shear and tensile force. Casting advantage is that can come up with more complex shape, the cost is low; Uniform forging advantage lies in the internal organization, there is no casting in porosity, inclusions and other harmful defects; From the casting production process difference between flange and forging flange, such as centrifugal flange is one of the casting flange.
