Heat treatment for Sedelon Valves
Heat treatment is a method used to alter the physical, and sometimes chemical properties of a material. The most common application is metallurgical.
It involves the use of heating or chilling, normally to extreme temperatures, to achieve a desired result such as hardening or softening of a material.
It applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally
Types of Heat Treatment (Steel):
1) Annealing / Normalizing,
2) Case hardening,
3) Precipitation hardening,
4) Tempering, and Quenching
The purpose of Heat Treatment:
