Normalizing | Metallurgy for Dummies

What is ,Normalizing, ? Normalization is a type of annealing process used to relieve stress in hardenable steels after cold work and to improve ductility and toughness properties. The ,steel, is heated slightly above its upper critical ,temperature, and held for sufficient time to allow new, smaller grains to form and high energy grain shapes to coalesce, also known as grain refinement.

2. Normalizing: Normalizing is a heat treatment process similar to annealing in which the Steel is heated to about 50 degree Celsius above the upper critical temperature followed by air cooling. This results in a softer state which will be lesser soft than that produced by annealing.

The normalizing of steel (Fig. 2) is carried out by heating ap-proximately 100°F (38°F) above the upper critical temperature (Ac 3 or Acm) followed by cooling in air to room temperature, or at no greater than one-bar pressure using nitrogen if the process is being run in a vacuum furnace. Normalizing is often considered from both a thermal and a

Normalizing, should not be confused with low-,temperature, annealing. (b) The upper limit of ranges should be used for large sections and the lower limit for smaller sections. Time held at ,temperature, varies from 1 h for light sections to 4 h for heavy sections and large furnace charges of high alloy ,steel,.
