Unit I FORGING EXTRUSION Q. 2. Differentiate hot and cold forging.
Ans. Hot forging- Hot forging is the plastic deformation of metal at a temperature above the recrystallization temperature and strain rate such that recrystallization occurs simultaneously with deformation. Cold forging - It is done at or near room temperature. Carbon and standard alloy steels are most commonly cold forged. The primary advantage of hot forging is the material saving achieved require Q. 1. What are the types of forging methods, which are generally used 2009
