The ASTM A815 specification covers two general classes i.e.-  WP and CR, of wrought ferritic, ferritic/ austenitic, as well as martensitic stainless steel fittings. These ASTM A815 Fittings are of typically either seamless or welded construction. Class WP fittings are further subdivided into four subclasses, which have been mentioned as follows - Classes WP-S, WP-W, WP-WX, and WP-WU. The material for Duplex Steel Buttweld Fittings must consist of products such as  bars, forgings, plates, or either seamless or welded tubular ones. The steel as per the ASTM A815 specification has to be melted by either of the following furnaces – i.e.  electric furnace, vacuum furnace, or electric furnace. Melting of steel is followed by vacuum or electroslag-consumable re-melting the metal.

Siddhagiri Metals & Tubes is one of the largest Duplex Fittings manufacturer and exporter of Duplex Socket Weld Fittings, Duplex Tube Fittings and Duplex Weld Fittings. We supply A182 Fittings, Duplex 2205 Fittings , Buy all Duplex Steel Buttweld Fittings Grade at factory price from India.

Forging or shaping operations to be done on the ASTM A815 Fittings could be performed by operations such as rolling, bending, fusion welding, hammering, pressing, piercing, extruding, upsetting, machining. Or the fittings could be shaped using a combination of two or more of these operations. The materials meant for Duplex Fittings need to undergo heat treatment and the material needs to follow the required cooling process as well as the tempering temperature as mentioned in the specification. Chemical and product analyses should be performed and they must also conform to the required chemical composition as specified. The ASTM A815 specification covers content of various elements such as carbon, copper, nitrogen, manganese, phosphorus, silicon, sulphur, nickel, chromium, molybdenum, and titanium. The mechanical properties of the Duplex 2205 Fittings  material needs to also conform to the required values in terms of its yield strength, tensile strength, elongation, as well as hardness properties.

According to Duplex Pipe and Fittings Suppliers in UAE grade 2205 is the most widely used duplex stainless steel grade. Fittings of this grade finds applications due to both their excellent corrosion resistance as well as their high strength. The composition of conventional duplex grade S31803 has been refined over the years by many steel Duplex Pipe and Fittings Suppliers in UAE, The resultant restricted composition range was endorsed as stainless steel grade UNS S32205 in the year 1996. 2205 grade Duplex Steel Buttweld Fittings are not generally well suited for use at temperatures exceeding the 300°C since it suffers from precipitation of brittle micro constituents. Further the Duplex Pipe Fittings can also not be used beyond a temperature of -50°C due to its ductile to brittle transition phase.

Applications of the Duplex Stainless Steel Fittings include their use in Chemical processing, transport and storage, Marine and other high chloride environments, Oil and Gas exploration and processing equipment, Pulp and paper digesters, liquor tanks as well as paper machines.

Duplex Steel Buttweld Fittings have excellent general resistance to corrosion, which is superior as compared to stainless steel Grade 316 in most environments. These Duplex Steel Pipe Fittings are known for their excellent resistance to localized corrosion including pitting, intergranular, as well as crevice corrosion. The CPT of Duplex Grooved Fittings 2205 is generally at least 35°C. This grade of Duplex SS Fittings is also resistant to chloride stress corrosion related cracking, otherwise referred to as SCC at temperatures of up to about 150 °C. Duplex stainless steel Grade 2205 tends to often perform well in environments in which otherwise would cause premature failure of austenitic grades. In fact, Duplex Stainless Steel Pipe Fittings tends to have better resistance to sea water then Grade 316. At Siddhagiri Metals & Tubes, we keep Duplex Fittings Stockist.

Although Duplex Stainless Steel Pipe Fittings of grade 2205 has good high temperature oxidation resistance, this alloy, similar to other grades of duplex stainless steels tends to suffers from embrittlement if held for even short times at temperatures which cross 300 °C. If the alloy gets embrittled, Duplex Fittings suppliers in India recommend using a full solution annealing treatment in order to rectified the embrittled alloy. Typically, Duplex stainless steel grade products are almost never used above a temperature of 300 °C.Solution treatment  or annealing can be performed on the Duplex Steel Buttweld Fittings by heating the alloy to a temperature between the range of 1020 °C up to 1100 °C followed by rapidly cooling the alloy. Although grade Duplex Steel Fittings cannot be hardened by thermal treatment, duplex stainless steel does work harden.
