ASTM A – / ASTM A – for Austenitic Cast Iron provided by Dandong Foundry in China. This is an America standard for the physical properties. Ni-Resist Iron has an austenitic matrix with about 10% alloy carbides. It is suitable for corrosive environments in sour well oils, salts, salt water acids. See the chemical composition and physical properties of ASTM A Grade 1, find alternative materials, and connect with suppliers.

In case no option is expressed, the manufacturer shall make the choice. Current edition approved Jan. If aatm tension test specimen shows obvious defects, another may be cut from the same test bar or from another test bar representing the same metal.
Last previous edition A — The materials shall undergo a nonmagnetic test which is based on the material’s attraction to a small steel horseshoe-type magnet and a magnetic permeability test in the event that nonmagnetic castings are specified.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
ASTM A436 Grade 1
If castings are to be heat treated, test bars shall be included in the same furnace load. A number in parentheses indicates the year of last reapproval. Austenitic gray iron is characterized by uniformly distributed graphite flakes, some carbides, and the presence of sufficient alloy content to produce an austenitic structure. The reduced section shall have a gradual taper from the ends toward the center, with the ends 0.
This standard is subject to revision at any time a463 the responsible technical committee and must be reviewed every? Otherwise, the austenite that is supersaturated with respect to carbon may reject carbon during service and produce dimensional changes.
