Stress Relief

Decreased tension inside a steel structure without altering heavily its hardness.

Stress relief allows to decrease the internal tension of steel without decreasing heavily its hardness.

Usually it is performed between 150-180 C° (carbon steel/low alloyed steels) and between 170-210 C° (case hardening steels).

Common usages

Reduction of structural tensions without altering its hardness

Pros
  • Reduction of structural tensions
  • Cons
  • Superficial steel tension may result useful in some cases to resist fatigue
