  Re: WHAT IS DIFFERENCE BETWEEN ANNEALING,TEMPERING AND NORMALIZING
Answer
# 1
All are different heat treatment process.In general heat
treatment process is used to impart desired mechanical
properties to materials.Annealing is the process of heating
the material and holding that for some time and then
cooling it in suitable rate(in air).it is used to refine
the grain size,to relieve the internal stresses.Tempering
is the process of heating the hardened material.it is used
to impart toughness.Normalizing is the process of heating
40 deg above recrystallization temp and cooling it in
furnace

Answer
# 2
ANNEALING - heating the material and cooling in furnace/air
to impart ductility,relieve stress,
TEMPERING - reheating below critical temperature after
quenching to increase ductility.
NORMALIZING- heating to achieve even grain structure.remove
effects of previous heat treatment

Answer
# 3
Annealing : Its a process in which first the component is
heated till austenitising temperature & then cooled by
keeping furnace off so that to increase ductility.

Normalising : Hardening process where the component is air
cooled after heating till austenitising temperature.

Tempering : After hardness, tempering is done to increase
ductility.
