Fine grain counts !
The purpose of normalizing steel is to form a uniform and as fine-grained as possible structure with a rather round grain, independent of the pre-treatment. Unalloyed steels in particular have the...

Heating up speed and cooling speed make the difference
Stress relief annealing serves to reduce internal stresses (= residual stresses) in the workpiece. For steel, it is usually carried out in a temperature range of 550 to 650°C – i.e. below AC1,...
