use of alloy chain slings in acid pickling chemical bath

Chain Sling User’s Manual

Chain Sling User’s Manual

does not recommend the use of alloy steel chain or chain slings for use in acid or pickling solutions. The high tensile strength of the heat treated alloy material in alloy steel chains is susceptible to hydrogen embrittlement when exposed to acids. Acid resisting Monel or stainless steel chains and sling components are preferred for this service.sp.info Stainless FoundryPickling – This is probably the most commonly used method. Use a solution of nitric and hydrofluoric acids in water. We use ASTM A380, solution D. The formula is specified in A380 as 6 – 25% HNO3 and ½ – 8% HF in water at 70 -140 F (21 – 60 C) for about 30 minutes. This is a strong cleaning solution and may etch highly finished surfaces.sp.info citric acid based passivation productsMar 09, 2010 · 2. Pickling – This is probably the most commonly used method.
