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.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

ASTM A436 Grade 1

The materials shall be manufactured by melting in any furnace that produces castings which includes cupolas, air furnaces, electric furnaces, crucible furnaces, and so forth. Otherwise, the austenite that is supersaturated with respect to carbon may reject carbon during service and produce dimensional changes. Types 1b, 2b, 3, and 5 may be attracted to a magnet.

NOTE 1—Alnico magnets should not be used. This specification covers austenitic gray iron castings that are used primarily for their resistance to heat, corrosion, and wear. This standard has been approved for use by agencies of the Department of Defense. Materials and Manufacture 4.

This nonmagnetic test is a convenient qualitative test only for Types 1, 2, and 4 and shall not be used as a basis for acceptance. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, silicon, manganese, nickel, copper, chromium, sulfur, and molybdenum. Tension Test Specimens Preparation for Delivery The six types shall conform to the requirements given in Table 2.

Drillings are not reliable because of the probable loss of graphite. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The test bars shall be cast in open molds made of suitable core sand with a minimum of 11?

ASTM A – 84() Standard Specification for Austenitic Gray Iron Castings

Austenitic gray iron is characterized by uniformly distributed graphite flakes, some carbides, and the presence of sufficient alloy content to produce an austenitic structure. If any tension test specimen shows obvious defects, another may be cut from the same test bar a463 from another test bar representing the same metal.


Tension tests shall be performed wherein specimens shall conform to required tensile strength and Brinell hardness. 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.
