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 these cases, either of the test specimens shown in Fig. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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.
Austenitic gray iron is characterized by uniformly distributed graphite? Surfaces of the a4436 shall be free of burnt-on sand and shall be reasonably smooth. Except as otherwise speci?
Responsibility for Inspection Austenitic gray iron is characterized by uniformly distributed graphite flakes, some carbides, and the presence of sufficient alloy content to produce an austenitic structure. NOTE 1—Alnico magnets should not be used. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
