| CORROSION RESISTANCE | 304 shows good corrosion resistance in a wide range of applications. As an example, 304 exhibits corrosion rates lower than 0.10 mm/year in the following media: -20% acetic acid at 800C. -90% formic acid at 200C. -20% phosphoric acid at 600C. -20% nitric acid at 500C. -90% sulphuric acid at 200C. -Toluene. -Milk. -Beer. -Juice. -Wine. | ||||||||
| SURFACE CLEANING | Wash the surface with neutral soap and water applied with a cloth or a brush without scratching the stainless steel. Then, always rinse the stainless steel with water to remove completely the cleaning agent. Finally, it is recommended to dry the surface to preserve a good superficial condition. In severe environments, a frequent cleaning is strongly recommended. | ||||||||
