The Adventures of Duke A9995. Pump Fittings Casting casted Pump parts, pump body, pump impeller, pump cover, pump flange and other fittings for pump industry.

It can get stability density castings for high pressure purpose. A valve company took exception, and indicated that duplex valve bodies and bonnets would be supplied per ASTM A If so kindly indicate your capability to supply the same. Metal melting, metal casting, resin sand casting and green sand casting. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.


Sand casting Tech sand casting technology, from material to pouring theory. Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking including sulfide stress corrosion crackingpitting, crevice corrosion and high strength when compared with other stainless alloys.

It finds applications due to both excellent corrosion resistance and high strength.


All standards from internet, only for study usage. The duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated.

It is also roughly double the strength of standard austentic stainless steels. The material may be adopted in ASME codes for specific products or applications, including: Combining values from the two systems may result in nonconformance with the standard.

Investment Casting Tech investment casting technology Die W995 Tech die casting technology, die casting process. However, A imposes some additional requirements:. Texas Manufacturing Expands Modestly, Outlook. Emerson Completes Acquisition of iSolutions I. What is the difference between these specifications? Each casting must be marked with a heat number or with a serial number traceable to a heat number. Custom Hydraulic Power Units. Historical Version s – view previous versions of standard.

The values stated in each system a95 not be exact equivalents; therefore, each system shall be used independently of the other. A is no longer used for pressure retaining castings. ASTM A lists tensile property requirements, but does not require that the tensile tests actually be performed.


Link to Active This link will always route to the current Active version of the standard. I would like to know whether therre is a casting equivalent for A Gr. China Castings November 22, at 6: Your email address will not be published. Rigging and Lifting of Large Valves Post: The grades of steels covered here are: Certification must be provided listing the chemical analysis of a9955 heat and the mechanical property test results.

Material a9995 Material technology, such as ductile iron, carbon steel, gray iron, stainless steel, malleable iron and alloy. Monitoring Pressure Relief Devices Post: A only requires post-weld heat treatment if Supplementary Requirement S33 is s995 on the purchase order.

Work Item s – proposed revisions of this standard. This specification covers austenitic-ferritic duplex stainless steel castings for valves, flanges, fittings, and other pressure-containing parts.

K November 21, at 8: For this reason alone, many specifications that don’t require actual tensile testing are not represented in these codes. ASTM A was reapproved without changes in
