Graphitic corrosion of ductile iron
http://everyspec.com/MIL-SPECS/MIL-SPECS-MIL-I/MIL-I-24137_11271/ WebMar 11, 2007 · INTRODUCTION Graphitic corrosion, or graphitization, occurs when the metallic constituents of gray iron are selectively removed or converted into corrosion products. This process leaves behind the graphite matrix of the gray iron, in the shape of the original casting.

WebThe ductile iron alloys have high strength and ductility combined with the same desirable properties of the gray iron alloys. They provide resistance to frictional wear, corrosion resistance, strength and oxidation resistance at high temperatures, nonmagnetic characteristics and, in some alloys, low thermal expansivity at ambient temperatures. WebThis article describes the properties, applications and heat treatment processes of high-alloy graphitic cast irons, including austenitic gray irons and austenitic ductile irons. It also provides a discussion on the heat treatment of high-silicon irons for heat resisting and corrosion resisting applications. Topics
