Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. However, the corrosion resistance of the least resistant duplex stainless steels is greater than that for the most commonly used grades of stainless steels, i.

ASTM A specification stands for stainless steel pipe fittings or buttweld fittings. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. Forging or shaping operations are performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations.

All information is based q815 our present knowledge and is given in good faith. Stainless A8815 Welded Pipe Fittingss is generally considered to be wieldable by the common fusion and resistance. Click Here to join Eng-Tips and talk with other members!

Thank you for this information and for informing me of wrong unit of measurement! Are you an Engineering professional? It is used in umbilicals, storage tanks and pressure vessels. The materials undergo heat treatment and follow the required cooling process and tempering temperature.

Although machinable, the high strengths of duplex stainless steels makes machining difficult. When desired, one or more of these may be specified in the order. Looking for some more information? The Eng-Tips staff will check this out and take appropriate action. No liability will be accepted by the Company in respect of any action taken by any third party in reliance thereon.

We at Ganpat Industrial Corporation ensure that all our materials go through strict quality tests before dispatching them to our astmm.

The strip sections in Stainless Steel EFW Pipe Fittingss may be air cooled, but heavy sections of the same should be water quenched to minimize exposure in the carbide precipitation region. Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.

I should have clarified as such.

My customers are mainly in South America. Link to Active This link will always route to the current Active version of the standard. Stainless Steel Seamless Pipe Fittingss have very excellent drawability, where grouping of xstm yield power and high elongation allows an effective forming of multifaceted shapes.

It is informational only and not an official aastm of the standard; the full text of the standard itself must be referred to for its use and application. Duplex stainless steels have good weldability. Class WP fittings are subdivided into four subclasses: The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting.

Stainless Steel – Duplex – ASTM A ~ S

Strengths of duplex stainless steels can in some cases be double that for austenitic stainless steels. The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products.

Defense manufacturing is all about project manufacturing and project accounting. 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 material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Whilst duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steels.

In particular, mechanical property requirements vary widely with temper, product and product dimensions. Ganpat Industrial Corporation known manufacturer of Stainless Steel Pipe Fittingss, which is a variation of the basic grade by means of having a higher chromium and lower carbon content.

Disclaimer This Data is indicative only and as such is not to be relied upon in place of the full specification. Last Datasheet Revision 14 November Their microstructures consist of a mixture of austenite and ferrite phases.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Asfm Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Duplex stainless steels are in most cases, tougher than ferritic stainless steels. Work Item s – proposed revisions of this standard.
