I would like to know whether therre is a casting equivalent for A Gr.

New Washer Application Search Tool. What is the difference between these specifications? Latest Post Popular Links Events.

However, A imposes some additional requirements:. Admiral Valve Announces Partnership with Diek. Gravity Die Castings Die casting products, mainly are cast aluminum alloy and zinc alloy with good dimensions. Each casting must be hydrostatically tested. The duplex stainless steels offer a combination of enhanced mechanical properties and corrosion resistance when properly balanced in composition and properly heat treated. It can get stability density ast for high pressure purpose.

Certification must be provided listing the chemical analysis of the heat and the mechanical property test results. Link to Active This link will always route to the current Active version of the standard.

Materials Q&A

Marking of heat numbers on castings is not required unless specified separately on the purchase order. It finds applications due to both excellent corrosion resistance and high strength.

Investment Casting Tech investment casting technology Die Casting Tech die casting technology, die casting process. Each casting must be marked with a heat number or with a serial number traceable to a heat number.

Material casting Material technology, such as ductile iron, carbon steel, gray iron, stainless steel, malleable iron and alloy. Related Standard duplex stainless steel. Rigging and Lifting of Large Valves Post: Despite Oil Prices Post: 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 material may be adopted in ASME codes for specific products or applications, including: The steel castings shall be heat-treated up to required temperature and shall undergo water quenching or rapid cooling asttm other means after heating.

Work Item s – proposed revisions of this standard. The grades of steels covered here are: It is also roughly double the strength of standard austentic stainless steels. Duplex stainless steel is designed to combine improved resistance to stress corrosion cracking including sulfide astmm corrosion crackingpitting, crevice corrosion and high strength when compared with other stainless alloys.

Duplex Stainless Steels

Combining values from the two systems may result in nonconformance with the standard. As such, many piping specifications include references to ASTM A and its various duplex grades for piping components such as valves. A imposes several other requirements that are not included in A nor A Looking for a career in the Valve Industry?
