F92 ASTM material specification. China Castings November 22, at 6: 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.
A valve company took exception, and indicated that duplex valve bodies and bonnets would be supplied per ASTM A Duplex AF51 is equivalent to: The material may be adopted in ASME codes for specific products or applications, including: A only requires post-weld heat treatment if Supplementary Requirement S33 is imposed on the purchase order.
ASTM A lists tensile property requirements, but does not require that the tensile tests actually be performed.
Despite Oil Prices Post: Leave a Reply Cancel reply Your email address will not be published. However, A imposes some additional requirements: Duplex S provides excellent guaranteed corrosion resistance, but it should be noted much of the Duplex S currently produced also dual conforms with Duplex S Texas Manufacturing Expands Modestly, Outlook. A grades will not be added for the same reason.
