Fig. 15 Sample of plain carbon steel after low-cyanide salt bath nitrocarburizing treatment (Process 3). The high level of apparent porosity is a characteristic of high sulfur content in the compound zone; dark areas are actually iron-sulfide nodules, not voids. More

Fig. 7 Plain carbon steel, hardened but not tempered. (a) Taper section (horizontal magnification 1200×, vertical magnification 13,080×) of surface layers that were abusively ground, producing martensite (white-etching constituent) and tempering (dark-etching bands). (b) Dark-etching bands More

Fig. 8 Tempered martensite is the best structure for nitriding. Plain carbon steels are generally not suitable because the resultant case will be very brittle and tend to spall. To determine the level of hardenability required to obtain a martensitic microstructure for nitriding, select More
