Wire Selection for Porcelain Coating


(2000)

Our company is interested in porcelain enamel coating of wire products (grills)and we have been told that we will need a very low concentration of carbon--even lower than what is in 1006 wire. Too much carbon will cause the porcelain to pop off of the wire, we have been told. If anyone who has experience in porcelain enamel coating on wire could respond to this, I would appreciate it. I have contacted several wire vendors and no one has wire with less than 0.02-0.03% carbon. Thanks

Yes, steel has to be decarburized to be enameled to eliminate outgassing surface defects. The carbon does not necessarily need to be eliminated. In interstitial-free (IF) steel, the carbon is tied up with alloying elements.
