Naxidic Acid for Pickling of Steel



(-----) 2006

We are using hydrochloric Acid for pickling of HRCA and CRCA materials. At low atmospheric temperatures we find that pickling rate is slower. I came to know that Naxidic acid is a remedy in such situations. Kindly let me know whether the addition of Naxidic acid is advisable. Thanking you.

Ask the 'Naxidic acid' vendor for data. It seems to be a conventional pickling acid + proprietary additive.

Dear Mr. Ken.

I came to know about Naxidic Acid from the vendor's web page. I don't have any idea how it works and its constitutents. Thanks for your reply.

This is a trade name for a proprietary additive, or mixture of pickling acid plus proprietary additive, Aurobind. Only the vendor can tell you what it is (and they will tell you very little because it is proprietary). Even if someone else told you what it was and what it did, the vendor is free to reformulate it at any time -- much as a Ford Thunderbird changed from a two-seat sports car to a four-seat luxury car, to a six-seat family car, to a two-seat luxury car at the whim of the trademark holder.
