Corrossion Data for Stellite #6
Corrossion Data for Stellite #6
(OP)
I am looking for corrosion data for Stellite #6 against Nitric Acid. I am interested in knowing the corrosion rates at various concentrations and if possible temperatures. Is this data available freely? if not, where can i buy it from?
Thank you,

RE: Corrossion Data for Stellite #6
Your first option is to visit the web site below, and see if you can obtain corrosion data for Stellite 6;
http://stellite.com/
Considering the scarcity in corrosion data for this hardfacing material, and if the stellite.com source does not provide information, you might want to visit the Haynes International web site below. Haynes has a technical brochure H-2082C, which is the Ultimet hardfacing alloy brochure. Ultimet alloy has a Co-Cr base chemical composition that would be similar in range to the family of Stellite 6 and Stellite 6113 alloys (per the chemical compositions listed by stellite.com) . This brochure lists valuable information regarding mechanical property data and corrosion information.

If you have no other source of corrosion information specific to Stellite 6, you might want to consider the information for Ultimet, as a guide. For boiling, 65% nitric acid solution (worst case), the corrosion rate is 8 mils per year for a cast product.

Once you added organics, especially the acids, the dissolution is straight forward in a hurry.

I also found this little pdf on the haynes website
http://www.haynesintl.com/pdf/h2087.pdf
According to this piece of information, the corrosion rate for investment cast Stellite 6 is 2890 mils/yr as compared to 8 mils/yr for the Ultimet Alloy in 65% boiling HNO3.
Thanks for your input.

Corrosion never sleeps, but it can be managed.
