Neelkamal Alloys LLP is a trusted Duplex Steel Fasteners manufacturer and supplier in Mumbai, India. We provide fastening solutions that are both corrosion-resistant and high-strength, specifically designed for the most demanding industrial applications. Our duplex nut bolts are engineered to operate effectively in harsh environments, including marine, offshore, petrochemical, and power plant systems, and are constructed from premium-grade duplex stainless steel. Our selection of duplex steel nuts, bolts, washers, studs, and screws are all precision-machined to meet the most stringent industry standards.
Duplex stainless steel is known for its balanced microstructure, combining the strength of ferritic and the corrosion resistance of austenitic stainless steel. The combination makes duplex fasteners exceptionally resistant to pitting, crevice corrosion, and stress corrosion cracking. We use high-quality duplex grades like UNS S31803 and S32205 to manufacture all our fasteners. Each item is produced in accordance with international standards such as ASTM A479, ASTM A182, DIN 1.4462, and ASME specifications, ensuring reliable performance in demanding conditions.
A wide range of duplex fasteners, such as hex bolts, massive hex nuts, flat and spring washers, threaded rods, stud bolts, and various screws, such as socket cap screws and machine screws, are available. The UNC, UNF, metric coarse, and fine threads are available in duplex fasteners, with diameters ranging from M6 to M64. We offer both standard and customized dimensions to accommodate the requirements of your project, whether you require fasteners for high-pressure pipelines, process equipment, structural connections, or valve assemblies.
Mechanical strength, dimensional accuracy, and corrosion resistance are meticulously assessed for each steel duplex fastener. Material test certificates (EN 10204 3.1), inspection reports, and optional third-party verification are all included in the documentation provided by Neelkamal Alloys LLP with each order. Our packaging ensures the safety and readiness for installation of duplex steel nuts, bolts, washers, studs, and screws during transit.
As a committed Duplex Steel Fasteners exporter, we serve clients across the USA, Europe, the Middle East, and Southeast Asia. Whether you are in need of a specific fastener configuration or are procuring bulk orders for industrial supply, Neelkamal Alloys LLP is prepared to provide you with a rapid response and dependable quality.
