Our product range includes Super Duplex Steel Hex Bolts, Anchor Bolts, U Bolts, Stud Bolts, and Heavy Nuts in grades such as S32750, S32760, and EN 1.4410 Super Duplex Steel. These grades contain higher amounts of chromium, molybdenum, and nitrogen, which enhance hardness and corrosion resistance. Surface finishes such as plain, polished, and coated options are available based on application requirements.
Super Duplex Steel Fasteners are widely used in oil and gas plants, offshore platforms, chemical processing units, marine equipment, heat exchangers, and pressure vessels. Their ability to withstand high pressure, high temperature, and seawater exposure makes them suitable for demanding environments where ordinary stainless steel fasteners may fail. These fasteners also offer excellent fatigue strength and long-term durability.
We supply Super Duplex Steel Fasteners in Mumbai and across India with complete quality documentation including Mill Test Certificates (MTC) and inspection reports. Each fastener is tested for chemical composition, mechanical properties, and dimensional accuracy. Customized sizes, special threading, and bulk supply options are available for domestic and export orders, ensuring reliable performance for industrial and infrastructure projects.
