Whilst duplex stainless steels are considered resistant to stress asfm cracking, they are not as resistant to this form of attack as ferritic stainless steels.
Register now while it’s still free! It is reasonable to expect specifications in these standards to be similar but not necessarily identical to those given in this datasheet. 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. You do NOT haveksi, but rather psi. This Data is indicative only and as such is not to be relied upon in place of the full specification.
The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting. The materials shall undergo heat treatment ast, shall follow the required cooling process and tempering temperature. The mechanical properties of the fitting material shall conform to the required values in yield strength, tensile strength, elongation, and hardness. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades.

The recommended filler material for stainless steel is The material for fittings shall consist of forgings, bars, awtm, or seamless 8a15 welded tubular products. 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. Within the text, the SI units are shown in brackets. Chemical 8a15 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 material for fittings shall consist of forgings, bars, plates, or seamless or welded tubular products. As a result, duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. Although asm, the high strengths of duplex stainless steels makes machining difficult. Tooling and work surfaces must be thoroughly cleaned before use. Duplex steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless.

Last Datasheet Revision 14 November We at Ganpat Industrial Corporation ensure that all our materials go through strict quality tests before dispatching them to our clients. But if you had parts forged then they should have been reheat treated, and then retested. They have high resistance to intergranular corrosion.

The strip sections in Stainless Steel EFW Pipe Fittingss may be air cooled, but heavy sections of the same should be s815 quenched to minimize exposure in the carbide precipitation region.
I have attached Table 4 as a A85 for review. Class WP fittings are subdivided into four subclasses: SS Pipe Fittingss is non-hardenable by heat treatment. The steel shall be melted by electric furnace, vacuum furnace, or electric furnace followed by vacuum or electroslag-consumable remelting.

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.
Siddhagiri Metals and Tubes Rating: Looking for some more information? Thank you for this information and for informing me of wrong unit of measurement! Duplex stainless steels are in most cases, tougher than ferritic stainless steels. The materials shall undergo heat treatment and shall follow aatm required cooling process and tempering temperature.
The mechanical properties of the pipe fitting material is tested for yield strength, tensile strength, elongation, and hardness. Class WP fittings are subdivided into four subclasses:
