Duplex 2205 Bolts and UNS S31803 Hex Nut/ Fasteners Manufacturer

UNS S31803 Hex Nut and Duplex Fasteners Manufacturer in India

We are a leading duplex fasteners manufacturer and we produce all kinds of stainless steel material made products. The duplex grade steel is a dual phase austenitic and ferritic steel that is used for high strength and corrosion resistance properties. The Duplex 2205 Bolts belongs to a specification of duplex called the standard duplex and it is the most used of duplex steels. We also produce Duplex Threaded Rod Our products go by the international standards such as the DIN 1.4462. This particular specification of material is used in processing equipment, transportation, storage, oil and gas exploration, high chloride ion rich environments, marine applications and many others. The Duplex Stainless Fasteners are used to fit accessories together in paper and pulp industrial machines, digesters, liquor tankers and in food storage containers. The fasteners are also used in sea water and marine applications where the corrosion risk is high. As the Duplex 2205 Studs can withstand high temperatures it is used in heat based applications, oil and gas industries and in chemical processing plants as well. Great Steel & Metals is a manufacturer and supplier of all kinds of standard duplex bolts and nuts. We offer bolts, screws and UNS S31803 Nuts of this material grade. Our Duplex 2205 Screws and other products are of superior quality and we test them under international standards. You can get a full list of our products and price lists as you contact us with any inquiries.
