Hi,
One of the requirements in the casting drawing is that after casting with HT300 material (equivalent to GC40), the casting shall be normalised and tempered.
I guess this is due to increase tensile strength.
Q1. Is it a common practice in casting industry?
Q2. Is it really possible to do normalisation and Temper together or one another?
