1、Nickel - chromium - iron alloy 825 ,due to it containing 30% of iron,   sometimes included in the super austenitic stainless steel series.  This kind of alloy and alloy20# is primarily used for sulfur and phosphorus in the variety of USES. 2、Although it has strong hydrochloric acid corrosion resistance of alloy 825 capacity, it is vulnerable to chloride pitting corrosion and crevice corrosion, especially in illiquid, stuffy solution.3、 Because of its high iron content,its resistance ability

to strong alkali and halogen corrosion resistant ability is lower than the one which containing more nickel.
