You can click the Top Right email! Gravity Die Castings Die casting products, mainly are cast aluminum alloy and zinc alloy with good dimensions.

A Grade 5A ASTM :: Total Materia

The duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated.

A grades will not be added for the same reason. Latest Post Popular Links Events. Combining asfm from the two systems may result in nonconformance with the standard.

Lost Foam Castings Lost foam casting products, ductile iron pipe fittings, valves Low Pressure Die Castings Lost pressure die casting products, mainly aluminum alloy casting products. In order to obtain a test report showing the actual chemistry and tensile test results, Supplementary Requirement S12 must also be a9995. 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 heat of material must be tensile tested. Pump Fittings Atsm casted Pump parts, pump body, pump impeller, pump cover, pump flange and other fittings for pump industry.


This alloy resists chloride environments and sulfide stress corrosion. ViewIn Technology for Mechanical Seals. Any casting that meets A also meets A The standard duplex S A F51 composition has been refined over many years, and the resulting composition range was endorsed as UNS S in All steels shall undergo tension test, and shall conform to the following mechanical requirements: Upcoming Valve Industry Events Reprints.

Despite Oil Prices Post: The Adventures of Duke Waters. It is the responsibility of the purchaser to determine which grade shall be furnished depending on design and service conditions, mechanical properties, and corrosionresistant characteristics.

Custom Hydraulic Power Units. Marking of heat numbers on castings is not required unless specified separately on the purchase order. 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. Monitoring Pressure Relief Devices Post: This specification covers austenitic-ferritic duplex stainless steel castings for valves, flanges, fittings, and aztm pressure-containing parts.

Tensile tests are only required if Supplementary Requirement S32 is specified on the purchase order. All standards from internet, only for study usage. For this reason alone, many specifications that don’t require actual tensile testing are not represented in these codes.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. ASTM A was reapproved without changes in Each casting must be marked with a heat number or with a serial number traceable to a heat number. It finds applications due to both excellent corrosion resistance and high strength. Rigging and Lifting of Large Valves Post: Machinery Fittings Casting casting products for usage of machinery.


A provides a definition for major weld repairs and requires post-weld heat treatment i. Sand casting Tech sand casting technology, from material to pouring theory. The grades of steels covered here are: Duplex AF51 is equivalent to: A imposes several other requirements that are not included in A nor A Certification must be provided listing the chemical analysis of the heat and the mechanical property test results.

Metal melting, metal casting, resin sand casting and green sand casting.
