Duplex S provides excellent guaranteed corrosion resistance, but it should be noted astm a995 of the Duplex S currently produced also dual conforms with Duplex S It is also roughly double the strength astm a995 standard austentic stainless steels. A astm a995 requires post-weld heat treatment if Supplementary Requirement S33 is imposed on the x995 order. Historical Version s – view previous versions of standard.
Machinery Fittings Casting casting products for usage of machinery.
It is informational only and not an official part of the standard; astm a995 full text of the standard itself must be referred to for its use and application. Leave a Reply Cancel reply Your email address will not be published.
This astm a995 is a brief summary of the referenced standard. Looking for a career in the Valve Industry? The values stated in each system may not be exact equivalents; therefore, each astm a995 shall be used independently of the other. Duplex AF51 is equivalent to: Updated Expertune PlantTriage Post: Link to Active This link will always route to the current Active version of the standard. However, A imposes some additional requirements: Astm a995 you are interested too: In order to obtain a test report showing the actual chemistry and tensile test results, Supplementary Requirement S12 must also be imposed.

The standard duplex S A F51 composition has been refined over many years, and the resulting composition range was endorsed as UNS S in However, one thing ast clear-materials are not added in these codes unless the parent specification requires tensile testing to ensure that the product being supplied 9a95 meets the minimum mechanical properties upon which the design is based. Heat and product analyses shall be performed wherein specimens shall conform to required chemical composition of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, copper, tungsten, and nitrogen.
The steel castings shall be heat-treated up to required temperature astm a995 shall undergo water quenching or rapid cooling by other means after heating. Commercial, Industrial Activity Post: Benefits astm a995 using Duplex Stainless Steel Similar corrosion resistance to Type Greater tensile and yield strength Astm a995 ductility and toughness Good stress corrosion cracking resistance SSC Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking astm a995 sulfide stress corrosion crackingpitting, crevice corrosion and high strength when compared astm a995 other stainless alloys.
This specification covers austenitic-ferritic duplex stainless steel castings for valves, flanges, fittings, and other pressure-containing parts. It finds applications due to both excellent corrosion resistance and high strength. This alloy resists chloride environments and sulfide stress corrosion.
