STRESS RELIEVE S093
A means to take residual stress out of an object.
This is very important with lapped seal faces, especially after carbon/ graphite has been inserted into a metal holder.
Stress relieving is also done to retard corrosion after metal is formed into a shape. Stressed metal corrodes at a rate faster than unstressed metal.
Stress relieving is accomplished by one of the following methods:
- Heat the part to its annealing temperature and then cool the part. Repeat this several times.
- Blast the part with small diameter “shot” to relieve manufactured or induced stresses.
- Let the face holder composite relax over a period of time and then relap the face.
