Austenitic stainless steel under different heat treatment techniques for the performance of the different resistance to corrosion and wear properties of a great relationship: the number and morphology of precipitates in the pure wear conditions, no corrosion, material quality loss entirely by mechanical factors, and austenitic stainless steel at 1100 ℃ for 8h under air cooling process of precipitation Fe-Cr-Mo intermetallic compound quantity is the most, and into a block, which helps to increase the strength of the matrix material, so the best wear resistance. In corrosion environment conditions have acid is, the precipitates formed at 950 ℃ for 8h air cooling process of dispersion, a bone mesh distribution in the matrix and the precipitates, compared to bulk 1100 ℃× 8h air cooling process, the corrosion wear bad is not easy to form brittle grinding, further it is beneficial to prevent migration of matrix material, the corrosion and wear interaction environment medium has excellent resistance to corrosion and wear properties.
