diamalloy 5849


Posted by chris ciochon on May 05, 2003 at 20:27:10:

i recently started using the diamalloy 5849 which is excellent against erosion and corrosion. i have now been told that the process in which these coated parts are working a flushed yearly with a diluted blend of hydro-chloric acid. is previous circumstances i have found that hydro-chloric acid eats away quite rapidly through chrome. my question is being that diamalloy 5849 is composed 86% tungsten carbide, 10% cobalt, adn 4% chromium, if the concentration of hydro-chloric acid is 5%, will it affect the coating during teh yearly flush?

thanks for any help yu can give me,
also if anyone has information on diamalloy 5849 and its effectiveness against acids can you please send it to me,
