Title: Surface modification to improve fireside corrosion resistance of Fe-Cr ferritic steels

Full Record
Other Related Research

Abstract

An article of manufacture and a method for providing an Fe--Cr ferritic steel article of manufacture having a surface layer modification for corrosion resistance. Fe--Cr ferritic steels can be modified to enhance their corrosion resistance to liquid coal ash and other chemical environments, which have chlorides or sulfates containing active species. The steel is modified to form an aluminide/silicide passivating layer to reduce such corrosion.

Heat and corrosion resistant cast CN-12 type stainless steel with improved high temperature strength and ductility

Patent Mazias, Philip J [Oak Ridge, TN]; McGreevy, Tim [Morton, IL]; Pollard, Michael James [East Peoria, IL]; ...

A cast stainless steel alloy and articles formed therefrom containing about 0.5 wt. % to about 10 wt. % manganese, 0.02 wt. % to 0.50 wt. % N, and less than 0.15 wt. % sulfur provides high temperature strength both in the matrix and at the grain boundaries without reducing ductility due to cracking along boundaries with continuous or nearly-continuous carbides. Alloys of the present invention also have increased nitrogen solubility thereby enhancing strength at all temperatures because nitride precipitates or nitrogen porosity during casting are not observed. The solubility of nitrogen is dramatically enhanced by the presence of manganese,more » « less
