Improper forging process will also appear large grain or uneven, hardening crack phenomenon, forging cost is higher than the casting flange.

锻造工艺不当也会出现晶粒大或不均，硬化裂纹现象，锻造成本高于铸造法兰。

Forging flange generally lower than cast flange carbon is not easy to rust, forging streamline, the organization is more dense, mechanical properties than casting flange;

锻造法兰一般比铸造法兰含碳低不易生锈，锻件流线型好，组织比较致密，机械性能优于铸造法兰；
