The materials shall undergo heat a851 and shall follow the required cooling process and tempering temperature. Although machinable, the high strengths of duplex stainless steels makes machining difficult. They are not quite as a8155 welded as the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding. 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 a85 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.

ASTM A815 Pipe Fittings

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.

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

We also provide Standard certificates like EN 3. 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.

At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic aatm. Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations.

When desired, one or more of these may be specified in the order. Datasheet Search Search Term: The recommended filler material for stainless steel is Download Now White Paper: As a astn, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels.

The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting. It is used in umbilicals, storage tanks and pressure vessels. Where we use a period between whole numbers and decimal places, they use commas.

ASTM A815 Super Duplex Steel Buttweld Fittings Manufacturer in India

Duplex stainless steels are in most cases, tougher than ferritic stainless steels. 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. By joining you are opting in to a185 e-mail.

Siddhagiri Metals and Tubes Manufacturer: The material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. Last Axtm Revision 14 November Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Even in chloride and sulphide environments, duplex stainless steels exhibit very high resistance to stress corrosion cracking. 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. The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness.

It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in aatm datasheet. The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness.

No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those sources. 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.

Class WP fittings are subdivided into four subclasses: Forging or shaping operations shall be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, machining or by combination of two or more of these operations.
