    An article appeared in the 8/12/11 issue of Pool & Spa News about the Ryznar Stability Index. This index is favored, by some heater and equipment manufacturers, because it affords greater protection against corrosion, than does the more familiar Langelier Index. It favors higher calcium hardness levels and/or higher pH levels. Corrosion resistance of SPA-C weathering steel sheet As we know, SPA-C weathering steel sheet is usually resistant to corrosion. SPA-C weathering steel sheet is very necessary for the corrosion surface treatment. It can not only extend the service life of SPA-C weathering steel sheet, but also realize the sustainable development concept of energy saving and environmental protection.
