All standards from internet, only for study usage. Astm a995 duplex stainless steels offer a combination of enhanced mechanical properties and corrosion astm a995 when properly balanced in composition and properly heat treated. Ensuring Pipeline Valve and Actuator Integrity. Historical Version s – view previous versions of standard. Duplex AF51 is equivalent to: This specification covers austenitic-ferritic duplex stainless steel castings for valves, flanges, fittings, and other pressure-containing parts.
It is the responsibility of the purchaser to determine which grade shall be furnished depending on design astm a995 service conditions, mechanical properties, and corrosionresistant characteristics. For this reason alone, many specifications that don’t require actual tensile testing are not represented in these codes.
It is satm roughly double the strength of standard austentic stainless steels.
