B.S. 1.8670 Heat Treatments
- Post weld heat treatment shall be within the temperature range 550°C to 620°C, with a maximum temperature of 25°C below the tempering range on the test certificate, for either 1 h per 25 mm wall thickness or 4 h, whichever is the greater. Heating and cooling rates shall be in accordance with the following:
- The rate of heating shall not exceed (5 500/T)°C/h or 55°C/h, whichever is the greater, where T is the wall thickness in mm.
- Test welds shall be cooled to a temperature of 400°C at a rate not exceeding (6 875/T)°C/h or 55°C/h, whichever is the greater.
