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.

Otherwise, the austenite that is supersaturated with respect to carbon may reject a463 during service and produce dimensional changes. A346 case no option is expressed, the manufacturer shall make the choice. Link to Active This link will always route to the current Active version of the standard.
Responsibility for Inspection 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.
This specification covers austenitic gray iron castings that are used primarily for their resistance to heat, corrosion, and wear. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Surfaces of the castings shall be free of burnt-on sand and shall be reasonably smooth.
