• Description:
  Because of U.S. dependency on imported critical metals, the Bureau of Mines has conducted research to evaluate the possible substitution of nitrided low-alloy steels for higher chromium- containing alloys. The corrosion data for nitrided steels are limited primarily to the soviet literature. The objective of this study was to determine the corrosion properties of six commercially nitrided low-alloy steels in a 5-wt % nacl solution at ph 4. Weight- loss tests indicated that, in deaerated test solutions, most of the nitrided steels were less corrosion resistant than nontreated steels. However, electrochemical tests indicated that under more oxidizing conditions, nitrided materials are converted to a passive state with a significantly reduced corrosion rate. Electro-chemical tests performed in an aerated environment confirmed the passivity of the samples in an oxidizing environment. [Description provided by NIOSH]
