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.
