  1. Hey there, Recently we switched from normalizing to annealing for some parts that we manufacture. Normalizing is much easier(of course) and significantly cheaper in our location. We usually soak parts for a half an hour before setting the temperature of the oven to a few thousand Fahrenheit, The hardness will be about 54RC, which can be changed to achieve 45-60RC when tempered again at a few thousand degree Fahrenheit. In the process of annealing heat treatment it is just that the temperature will be much lower. It is just that normalizing is resulting in scaling(looks more like lumps) which otherwise is not present in annealing. The lump does reduce if we reduce the load! We have just started in the forging business and would like to know experts opinion. What are your thoughts on this one?
