Nickel Fasteners Manufacturer, Supplier & Exporter

Sumit Impex is a leading manufacturer and supplier of high-performance nickel alloy fasteners, offering an extensive range of bolts, nuts, screws, washers, studs, and threaded rods engineered for superior durability in highly corrosive and high-temperature environments. As a trusted nickel alloy fasteners manufacturer in India, we focus on delivering precision-machined products made from premium nickel-based grades to meet the critical requirements of industries such as chemical processing, marine engineering, power generation, oil & gas, refineries, paper & pulp, and aerospace. Our fasteners are manufactured as per ASTM, ASME, DIN, and ISO standards, ensuring global compatibility and long-term reliability.

Nickel fasteners are widely preferred for applications where ordinary stainless steel fasteners fail, due to their exceptional resistance to oxidation, pitting, crevice corrosion, carburization, and chloride stress-corrosion cracking. Nickel alloys such as Inconel 600, 625, 718, Monel 400, K500, Hastelloy C22, C276, Nickel 200/201, and Alloy 20 offer outstanding stability in extreme temperatures, sometimes exceeding 1000°C, and maintain high tensile strength even under heavy loads. These fasteners perform efficiently in both acidic and alkaline conditions and are often used in heat exchangers, reactor vessels, seawater equipment, furnaces, steam boilers, and high-pressure systems where maximum corrosion resistance is required.

At Sumit Impex, every batch of nickel alloy bolts, nuts, screws, and washers undergoes a comprehensive testing and inspection process to ensure superior quality and consistency. Our quality checks include PMI testing for correct material identification, flaring and flattening tests for mechanical strength, micro and macro testing for structural analysis, and pitting resistance tests to ensure suitability for chloride-rich environments. We also conduct hardness tests, tensile tests, 100% radiography, and surface finish inspections to maintain strict compliance with international standards. Third-party inspection reports from agencies like TUV, BV, SGS, and LLOYD’S can be provided to guarantee complete traceability and customer confidence.

Sumit Impex supplies nickel alloy fasteners that offer long service life, excellent dimensional accuracy, and consistent performance across a wide range of industrial applications. Their ability to withstand thermal shock, aggressive chemicals, fluctuating pressures, and seawater exposure makes them the ideal choice for customers looking for durable and maintenance-free fasteners. With a strong manufacturing base, ready stock availability, custom size production, and competitive pricing, we continue to serve as a preferred nickel alloy fasteners supplier for clients across India and international markets.
