We are a leading Duplex 2205 Bolts Supplier in Mumbai and manufacture these bolts to meet international quality standards like ASTM, ASME, DIN and ISO. We produce our Duplex 2205 fasteners from high-quality duplex stainless steel and use advanced methods like hot forging, CNC machining, thread rolling and heat treatment. This ensures great strength, resistance to corrosion, precise dimensions and long-lasting strength. We are a top supplier and exporter of Duplex 2205 bolts around the world as we have a strong manufacturing capability and a global supply network.

What Are Duplex 2205 Bolts?

Duplex 2205 bolts are made of Grade 2205 Duplex Stainless Steel (UNS S32205/S31803) which is known for its dual-phase austenitic–ferritic microstructure.  This combination has better mechanical strength, toughness and resistance to pitting, crevice corrosion, and stress corrosion cracking than other blends.  Duplex 2205 bolts are used in heavy engineering, offshore work, desalination plants, chemical processing, marine equipment, and systems that work at high pressure.  It is perfect for tough industrial uses as it is very strong, resistant to rust, and can work in harsh conditions.

We manufacture all of our Duplex 2205 bolts to internationally recognized standards like ASTM A182, ASTM A276, ASTM A479, ASTM A193, ASTM A320, DIN 933, DIN 931, ISO 4014, and ISO 4017.  These standards set the rules for hardness, chemical composition, mechanical strength, and dimensional accuracy. Manufacturing to strict standards ensures that offshore platforms, heat exchangers, pressure vessels, and chemical processing systems can all work together safely and reliably.

We manufacture our Duplex 2205 bolts using advanced and precise methods. These include hot forging to shape the bolts, CNC machining to make sure it is the right size, thread rolling to make it stronger, heat treatment to make the microstructure perfect, pickling and passivation to make it as corrosion-resistant as possible. We check the tensile strength, hardness, microstructure, and dimensions of each bolt to ensure it follows international standards. Our controlled heat treatment process ensures that the right amount of ferrite and austenite phases are present, giving the material great mechanical performance and resistance to corrosion.

Duplex 2205 bolts have many advantages over traditional stainless steel fasteners like SS 304 and SS 316. It is  twice as strong, resists fatigue and stress corrosion cracking better, and works better in environments with a lot of chloride.  Even in seawater and harsh chemicals duplex 2205 bolts resist pitting or crevice corrosion.  As it is very strong, industries can use smaller bolts without losing load capacity. This makes it a cost-effective choice for important applications.

We manufacture a complete range of Duplex 2205 bolts that can be used in different industries.  We supply different kinds of bolts, such as Duplex 2205 Hex Bolts, Heavy Hex Bolts, Machine Bolts, Carriage Bolts, Anchor Bolts, Flange Bolts, U Bolts, J Bolts, Stud Bolts, Threaded Bolts, Socket Cap Screws, and Countersunk Bolts.  Each bolt is made with strict quality control standards and high-tech machines to ensure that the threading is correct, the mechanical properties are consistent, and the surface is intact.  We offer both standard and custom Duplex 2205 bolts to meet the needs of our customers.

Duplex 2205 has the perfect balance of chromium, nickel, molybdenum, nitrogen, and low carbon content.  This combination gives the material high mechanical strength, great resistance to corrosion, and great resistance to stress corrosion cracking. We provide complete Material Test Certificates (MTC EN 10204 3.1) with full chemical composition details to ensure transparency and traceability

Duplex 2205 bolts have high tensile strength, high yield strength, controlled hardness, great toughness and great resistance to fatigue.  These traits make sure that the product works well in environments with high pressure, high stress and corrosion. Duplex 2205 bolts can handle high temperatures without losing their strength, which makes them ideal for heat exchangers, boilers, and power generation systems.

We supply Duplex 2205 bolts in different lengths and diameters from M6 to M100.  We offer both metric and imperial sizes that meet different standards like ASTM, ASME, DIN, and ISO.  We can make bolts with custom sizes, special threads and dimensions that aren’t standard depending on what the customer wants.  We test and manufacture each bolt to ensure it meets the right tolerances and works well.

Duplex 2205 bolts are heat treated and solution annealed in a controlled way to make it stronger, tougher and more resistant to corrosion. The right heat treatment ensures that the ferrite austenite balance is perfect, the hardness is even and the material lasts longer. We supply Duplex 2205 bolts with hardness and mechanical values certified as per ASTM specifications.

Duplex 2205 bolts are very resistant to rust in tough environments. It resists  pitting, crevice corrosion, stress corrosion cracking, or general corrosion, even in seawater, brine, acidic solutions, and alkaline environments.  As it has high amounts of chromium, molybdenum, and nitrogen, it is ideal for use in offshore platforms, marine pipelines, desalination plants, and chemical storage tanks.

We provide Duplex 2205 bolts with different surface finishes like pickled, passivated, polished, black oxide coated and anti corrosive coated. These finishes make the surface more resistant to rust, look better and improve durability. We can customize coatings based on customer and project needs.

We conduct comprehensive tests on all Duplex 2205 bolts such as mechanical tests, hardness tests, PMI tests, IGC tests, microstructure examinations, third-party inspections and tests of their size accuracy. We provide MTC EN 10204 3.1 certification which means compliance with all international standards.

Duplex 2205 bolts are used in multiple industries like oil and gas, petrochemical, marine engineering, desalination plants, chemical processing, power generation, pulp and paper, mining, construction, and offshore engineering industries. It works well for structural parts, pump assemblies, valves, pipelines, heat exchangers and equipment that comes into contact with seawater and strong chemicals.

The price of Duplex 2205 bolts in India varies based on their diameter, length, grade, coating, and the standards used to make them.  Duplex 2205 bolts usually cost ₹450 per kg or more but prices can change depending on the market and how many you need.  We have affordable prices, bulk order discounts and materials that are fully certified.

To keep it from rusting and getting damaged during shipping, all Duplex 2205 bolts are packed in export-quality materials like wooden boxes, sealed plastic bags, and moisture-proof packaging. Our global logistics support ensures timely delivery across India and worldwide, following international shipping standards.
