It is used in umbilicals, storage tanks and pressure vessels. My customer’s engineer is giving me a hard time about this reading on axtm MTR.

asmt Current News Archive Standard Technically. I should have atsm as such. The materials shall undergo heat treatment and shall follow the required cooling process and tempering temperature. All standard welding processes can be used. The Eng-Tips staff will check this out and take appropriate action. We are the exporter and manufacturer of these pipe fittings which are high quality and provides high mechanical strength, good weldability and good corrosion resistance. Thank you for this information and for informing me of wrong unit of measurement!

Are you an Engineering professional? We also provide Standard certificates like EN 3. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Chemical and product analyses shall be performed and shall conform to aastm required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen, and titanium.

The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products.

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 adtm application. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels.

Chemical and product analyses shall be performed and shall conform to the required chemical composition in carbon, manganese, phosphorus, silicon, sulfur, nickel, chromium, molybdenum, copper, nitrogen, and titanium. I want to ask the experts out there a question pertaining to common ASTM practices. At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic grades. Offer on Fasteners Sitemap. ASTM A specification stands for stainless steel pipe fittings or buttweld fittings.

Stainless Steel Seamless Pipe Fittingss have very excellent drawability, where grouping of low yield power and high elongation allows an effective forming of multifaceted shapes. Class WP fittings are subdivided into xstm subclasses: This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.

Stainless Steel – Duplex – ASTM A ~ S

Siddhagiri Metals and Tubes Rating: Within the text, the SI units are shown in brackets. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Class WP-S fittings are those manufactured from seamless product by a seamless method of manufacture marked with class symbol WP-S ; Class WP-W fittings are those which contain welds where the fitting fabrication or construction welds have been radiographed marked with class symbol WP-W ; and Class WP-WX fittings are those which contain welds where all welds have been radiographed marked with class symbol WP-WX ; and Class WP-WU fittings are those which contain welds where all welds have been ultrasonically tested marked with class symbol WP-WU.

The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness.

The mechanical properties of the pipe fitting material is tested for yield strength, tensile strength, elongation, and hardness. The stainless steel is melted in electric furnace, vacuum furnace followed by vacuum or electroslag-consumable remelting. But if you had parts forged then they should have been reheat treated, and then retested.
