When proper precautions are taken, Zr702 Zirconium (UNS R60702) can be an excellent material of construction for a wide variety of hydrochloric acid applications. In some circumstances zirconium can be susceptible to stress corrosion cracking, pitting, and/or intergranular corrosion in these types of environments. The effects of different material conditioning, including heat treatment and surface preparation, on the corrosion resistance of zirconium 702 in 15% and 36% hydrochloric acid will be examined. New corrosion data from the corrosion lab will be presented. Practical recommendations will be given for chemical conditioning and heat treatment of Zirconium Grade 702 to be used in hydrochloric acid environments.
