Aashish Metal & Alloys is a supplier of high performance Duplex Steel S31803 and S32205 socket fittings, which are demanded in the harsh environment where high levels of corrosion resistance and mechanical strength are required. These socket weld fittings, tees, crosses, couplings, unions, caps and plugs that are manufactured with ASTM A182 Duplex S31803 and Duplex 2205 provide outstanding service in sustaining resistance to stress corrosion cracking, pitting, and chloride atmosphere. Their ferritic-austenitic microstructure is balanced hence making them withstand longer durability than the conventional stainless steels and can be used in continuous environments of temperature fluctuations and other aggressive media.
The ASME B1611 Duplex S31803 socket weld fittings and WNR 1.4462 socket weld tee and cross fittings are extensively used in the offshore platform, desalination units, refineries and chemical processing plant. These fittings offer predictable behavior in tensile loading, oxygen atmosphere and dynamic loading, where more common grades (304 or 316L) can meet failure. Duplex S32205 socket weld couplings and unions are designed to have increased SCC resistance in sodium-chloride applications, where socket weld caps and plugs resist well in closing and sealing applications.
Our Duplex 2205 socket weld fittings are used by customers because of their reliability and dimensional accuracy and long service life. As we are one of the major suppliers in Mumbai, India, we assure of consistency, accuracy in machining as well as availability of our products when it is urgent to be used in a project.

Aashish Metal & Alloys provide the entire solution of ASTM A182 Duplex S31803 and S32205 socket weld fittings designed to operate in critical piping systems, which demand high strength, chloride resistance and long life performance. Our socket weld elbows, tees, crosses, couplings, unions, caps, and plugs are made of Duplex 2205 grade with a balanced ferritic-austenitic structure, which provides superior resistance to pitting, crevice corrosion and stress corrosion cracking.
Our ASME B1611 Duplex S3181 socket weld tee and WNR 1.4462 socket weld cross are designed to satisfy the high industrial standards and provide a high tensile strength and a high level of dimensional accuracy. These fittings can be used under high pressure conditions and with high pressure systems such as Class 3000 and Class 6000 which require long term performance. When choosing materials to be used in seawater, brine and chloride-rich conditions, engineers tend to compare the Duplex 2205 fittings with the Super Duplex S32750 S32760 socket weld fittings by ensuring that the latter would be more resistant in offshore and desalination applications.
Super Duplex F55 socket weld fittings are also used in industries where there is need to achieve high strength and durability in the aggressive chemical processing and high temperature processes. Our Duplex S32205 socket weld caps and plugs are still very successfully used in seal and termination tasks in petrochemical, marine engineering and water treatment plants.
We also add other models like Duplex 2205 forged elbows and UNS S31803/UNS S32205 couplings which give engineers all possible options on corrosive media loads including fluctuating pressure loads. Being a reliable supplier in Mumbai, India, we provide the delivery of consistent quality, accurate machining, stringent QC, and on-time delivery of domestic and international projects.

Applications of Duplex Steel S32205 Socket Weld Fittings
These Duplex Steel S32205 socket weld fittings are highly popular in those areas where extremely high strength, resistant to corrosion as well as very durable fittings are required. Their balanced ferritic austenitic structure offers unusually high levels of pitting, crevice, and stress corrosion cracking protection, and are suitable in a very broad spectrum of industrial systems. These socket weld elbows, tees, crosses, and couplings can be relied upon in challenging engineering environments because S32205 is known to be more resistant in chloride-laden, high pressure as well as fluctuating temperature settings.
Application Industries:
- The solution may take the form of chemical processing stations that handle aggressive fluids and corrosive fluids.
- High temperature and pressure cycle petrochemical and refinery units.
- Seawater lines, risers, pumps and desalination systems Offshore and marine industry.

Frequently Asked Questions on Duplex and Super Weld Fittings
Duplex Steel S31803/S32205 socket weld fittings are used in high-pressure and corrosion-prone systems such as offshore pipelines, chemical processing plants, desalination units, heat exchangers, and marine fluid handling. Their high strength and excellent chloride resistance make them ideal for demanding environments.
S32205 duplex fittings offer higher yield strength, better resistance to pitting and crevice corrosion, and improved performance in chloride-rich environments compared to SS 304/316. This makes them more suitable for aggressive industrial applications.
These fittings are typically manufactured according to ASTM A182, ASME SA182, and ASME B16.11 standards, ensuring dimensional accuracy, proper pressure ratings, and compatibility with high-pressure forged piping systems.
Yes. Duplex S32205 has excellent resistance to seawater corrosion, biofouling, and chloride-induced stress corrosion cracking, making it one of the most reliable materials for offshore and marine pipelines.
Common types include socket weld elbows, tees, crosses, couplings, unions, caps, plugs, lateral tees, and pipe nipples. These fittings are used to change direction, branch flow, or ensure leak-proof sealing in high-pressure lines.
Yes. These fittings are widely used in Class 3000, 6000, and even 9000 systems due to their superior yield strength and resistance to stress corrosion cracking, ensuring long service life under extreme operating conditions.
Both grades belong to Duplex 2205, but S32205 has slightly improved nitrogen content, which enhances corrosion resistance and mechanical strength. They are largely interchangeable, but S32205 is preferred for more aggressive or chloride-rich environments.
