Summary

The subjects gives an overview under-used to be owing to physical, mechanical and metallurgical parameter forging on structure and mechanical properties free and drop forgings. In technological parts is attention sight on warming-up steel, forming machine and equipment forge, on demand on input blank stock on one's behalf hammering, technological processing free and die forgings, heat treatment and verification forgings.
