The effects of these pollutants influence and oil and grease similar. Using a clean brush and water or alkaline cleaning agent to clean washing, can also use the high-pressure water or steam washing.
Mainly to the ferrite in the using condition of stainless steel. Chromium content in 11%~30%, has a body-centered cubic crystal structure. This kind of steel is usually does not contain nickel, sometimes also contain a small amount of Mo, Ti, Nb wait for element, this kind of steel with high coefficient of thermal conductivity, small coefficient of expansion, good oxidation resistance, stress corrosion resistance excellent characteristics, used for the manufacture of air resistance, water vapor, water and oxidizing acid corrosion of parts. This kind of steel plastic shortcomings, post-weld ductility and corrosion resistance decrease, which limits its application. Refining technology (AOD or VOD) can use carbon, nitrogen and other interstitial element is reduced greatly, so this kind of steel is widely used
