View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.UNILOY 434 is a medium-chromium (17%), non-hardening, ferritic stainless steel containing an addition of molybdenum (nominally 1%). The molybdenum addition creates a grade with increased resistance to corrosion. This steel (when compared with the molybdenum-free grade, AISI Type 430 or Uniloy 430) shows improved resistance to pitting attack from various de-icing chemicals. In addition, the color of Uniloy 434, when buffed, closely resembles that of bright chromium plate. Hence a popular application for Uniloy 434 is automotive trim.
