As a result the duration of exposure to the tempering temperature has no effect on the strip material's final hardness, which is instead determined exclusively by the tempering temperature.

The wire is manufactured by undergoing hardening and tempering and the tempering temperature is 645°C or more.

For some types of steels the holding time at the tempering temperature is of great importance; an extended holding time will correspond to a higher temperature.

The welding temperature, for example less than 250 °C, can be well below the tempering temperature of the treated material e.g. steel, and this avoids harmful effects to the steel material.

Subsequently to the quenching treatment, the pipe is subjected to a tempering treatment in which it is heated to a tempering temperature of 450-550°C, excluding 450°C, and then cooled.
