Corrosion resistance: 1. Use of media such as water, acetone, alcohol, ammonia, barium carbonate, benzene (WCB material temperature using -29 ° C - 425 ° C).2. Use of media such as particles, oils, pulp, carbon dioxide gas (stainless steel can be used at a temperature of -60 ° C - 232 ° C).3. Strictly prohibit the use of fluorine-containing ionic liquids (eg, HF, etc.) can not be used in the strong alkali and phosphoric acid (temperature less than 150 ° C, concentration > 30%).4. The general operating temperature of stainless steel ≤ 150 ° C, pressure range 0.6-2.5 MPA, over this provision should be specified when ordering. Stainless steel general operating temperature ≤ 150 ℃, pressure range 0.6-2.5MPA, more than this provision should be specified when ordering.
