Microstructure examination Heat treatment list Huey test certificate All semi-worked pieces are carefully heat treated, in order do not remove more that five millimeters on the finished pieces. Heat treatment diagram 8. urea Service Valves Severe tests are made in order to verify the good corrosion resistance and microstructure type of the material. Each sample of material is put in a corrosive bath for five cycles, and each cycle lasts 48 hours. At the end of each cycle, the sample is weighed using a scale capable to weigh up four numbers after the zero.

4 At the end of test, the sample is micrographic and metallographic examinated. urea Service Valves 9.
