    Abstract

    The Materials Technology Institute (MTI) of the Chemical Process Industries, Inc. has selected a series of laboratory corrosion tests to provide guideline information on new wrought iron- and nickel-base corrosion resistant alloys. Data obtained from these procedures are expected to provide the materials engineer with a reasonable assessment of the probable utility of a new alloy in a variety of environments or corrosion conditions and thus facilitate the commercial usage of such alloys. The test procedures are based essentially on ASTM methods. Test procedures are specified in sufficient detail to insure comparable data being obtained by different laboratories. Two basic concepts are used: (1) in each test a critical test factor is selected as the criterion for corrosion resistance of the alloys and (2) a control alloy is selected for each test, specimens of the control alloy being supplied by MTI. There are five test procedures: one for general corrosion, two for crevice corrosion, and two for stress corrosion cracking.
