The differents between forged flange and casting flange

what is the difference between the forged flanges and casting flanges? The answer is: when forging, the organization of the materials will be high internal pressure and defects will disappear and the density increase, make the internal organization of more uniform, and at the same time, make the continuous mechanical properties improve greatly. After forging, must heat treatment. This is the performance different between casting flange and  forging flanges.

The streamlined and the organization of forging is good, dense is good too, but the internal organization and streamline of casting part is poor (if it is cutting part, streamline is worse)

Forging part can withstand the shear strength and tensile force higher  than casting part.

Casting flanges, blank shape and size accurate, manufactured. Low cost. But small have cast defects (vent. Crack with).

Forging flanges internal organization. Mechanical performance is better than even casting flange forging process. Not also can appear grain big or not all. Sclerosis crack phenomenon. Forging costs than casting flange.

Forging flanges flanges carbon than general casting low is not easy to rust

If the shape is simpler, or forging a little bit better, word of batch production cost is not very tall, and forging can receive more even than the organization, the mechanical properties of casting is much better.
If the shape only consider using complex casting method.

Forging of various performance than the casting far. Cost and also higher than that of casting. Often used to teach important forging work conditions, often the working pressure, temperature, medium parameter determination. This flange standards and your design product standards to have specific provision.
