... Abstract A large portion of the four-hole Lane plate disintegrated and consisted mainly of corrosion products after remaining in the body for 26 years. Transformation structures and carbides were exhibited by the plate which was made from chromium steel. Minimal corrosion was exhibited by the...

... Abstract Examples of metallic inclusions in steels of various types are presented. The structure of an inclusion in an annealed Fe-1C-1.5Cr steel consisted of ferrite with lamellar pearlite. The carbon content of the inclusion was therefore considerably lower than that of the chromium steel and...

... Abstract High-chromium steel pipes 42.25 x 3.25 mm from a blast furnace gas fired recuperator for the preheating of air were heavily oxidized and perforated in places. It was found that the blast furnace gas had a high sulfur content. Both the carburization and the formation of sulfide proved...

... manufactured from a 0.5% carbon, 1% chromium steel heat treated to give a hardness value of 300 VDP. The material was in the hardened and tempered condition and showed no abnormalities which would predispose to early failure. The content of non-metallic matter was only of nominal amount. Failure of the shaft...
