Abstract
Types 316L (UNS S31603) and 304L (UNS S30403) sintered stainless steel s (SS) were produced in a laboratory furnace at 1,330 degrees C and in filtrated with copper and bronze in different percentages to determine their effect on the corrosion resistance of the presintered SS. Corro sion resistance was studied by immersion in sulfuric (H2SO4), hydrochl oric (HCl), and nitric (HNO3) acids and by electrochemical potentiokin etic reactivation (EPR) tests. Both copper and bronze improved corrosi on resistance highly in HCl and boiling H2SO4. Results of EPR and bell ing H2SO4 immersion tests showed good concordance.
