Heat treatment

Many materials require heat treatment to achieve the correct condition or strength. Carbon steels are hardened and tem­pered to achieve high strength, usually at the expense of ductil­ity. Austenitic stainless steels are stress-relieved, softened or solution-annealed to modify the physical or chemical proper­ties. The final condition is usually confirmed by taking hardness readings. When components are heat treated to achieve spe­cific physical properties a test piece is heat treated as well. The necessary physical tests are conducted on the test piece.

The customer may request a certificate detailing the duration of the heat treatment and the temperature achieved at specified intervals. If necessary a continuous trace of the temperatures may be provided.
