However, one thing is clear-materials are not added in these codes unless the parent specification requires tensile testing to ensure that the product being supplied actually meets the minimum mechanical properties upon which the design is based.

Each casting must be marked qstm a heat number or with a serial number traceable to a heat number. ASTM A was reapproved without changes in A imposes several other requirements that are not included in A nor A Metal melting, metal casting, resin sand casting and green sand casting. 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.


Each heat of material must be tensile tested. Emerson Completes Acquisition of iSolutions I.

A provides a definition for major weld repairs and requires post-weld heat treatment i. Investment Casting Tech investment casting technology Die Casting Tech die casting technology, die casting process. A grades will not atsm added sstm the same reason. Gravity Die Castings Die casting products, mainly are cast aluminum alloy and zinc alloy with good dimensions.

You can click the Top Right email! Work Item s – proposed revisions of this standard. The standard duplex S A F51 composition has been refined over many years, and the resulting composition range was endorsed as UNS S in 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 Looking for a career in the Valve Industry?


Each casting must be hydrostatically tested. A valve company took exception, and indicated that duplex valve bodies and bonnets would be supplied per ASTM A Machinery Fittings Casting casting products for usage of machinery. Texas Manufacturing Expands Modestly, Outlook. Link to Active This link will always route to the current Active version of the standard. ASTM qstm not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Custom Hydraulic Power Units. Any casting that meets A also meets A As such, many piping specifications include references to ASTM A and its various duplex grades for piping components such as valves. New Washer Application Search Tool. The Adventures of Duke Waters. China Castings November 22, at 6: Pump Fittings Casting casted Pump parts, pump body, pump impeller, pump cover, pump flange and other fittings for pump industry.

Emerson Completes Acquisition of iSolutions Inc. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. What is the difference between these specifications?

For this reason alone, many specifications that don’t require actual tensile testing are not represented in these codes. Material casting Material technology, such as ductile iron, carbon steel, gray iron, stainless steel, malleable iron and alloy.


Certification must be provided listing the chemical analysis of the heat and the mechanical property test results. Leave a Reply Cancel reply Your email address will not be published. If so kindly indicate your capability to supply the same.

It is informational only aastm not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This alloy resists chloride environments and sulfide stress corrosion. Tensile tests are only required if Supplementary Requirement S32 is specified on the purchase order.

Shale Work Up in U. Upcoming Valve Industry Events Reprints. This specification covers austenitic-ferritic duplex stainless steel castings for valves, flanges, asrm, and other pressure-containing parts. K November 21, at 8: Historical Version s – view previous versions of standard.

Your email address will not be published. In order to obtain a test report showing the actual chemistry and tensile test results, Supplementary Requirement S12 must also be imposed. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, silicon, phosphorus, a9995, chromium, nickel, molybdenum, copper, tungsten, and nitrogen. ASTM A lists tensile property requirements, but does not require that the tensile tests actually be performed.

Sand casting Tech sand casting technology, from material to pouring theory. The duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated.
