The tensile properti. es of K418 cast alloys by fine graincasting process and coventionally cast process have been determined at different temperatures.
测试了不同温度下细晶铸造和普通铸造K418合金的拉伸性能。
2
The casting is usually a fine graincasting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical situation with pipes.
这种铸件通常为外径处晶粒非常细小的细晶粒铸件，能耐大气腐蚀，典型的情况是管子。

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