3. Heat Treatment

Pipe fittings of ASTM A234 alloy steel, after forming at an elevated temperature, shall be cooled to a temperature. below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air.

1. Grade WP911 shall be normalized in the temperature range of 1900 to 1975 °F [1040 to 1080 °C], and tempered in the temperature range of 1365 to 1435 °F [740 to 780 °C] as a final heat treatment.
