Overview Technical Specifications Properties Types Materials FAQ

Overview

Our Nickel Alloy Fasteners are produced with precision to meet international standards such as ASTM, ASME, ISO, and DIN. Using advanced CNC machining, heat treatment, and surface finishing techniques, Steelvron ensures that each fastener exhibits exceptional tensile strength, hardness, and resistance to stress corrosion cracking. These processes enhance durability, toughness, and performance, even under fluctuating temperatures, high pressures, or aggressive chemical exposure.

Steelvron offers a wide range of nickel alloy grades – Inconel (625, 718), Monel (400, K500), and Hastelloy (C22, C276) – each designed for specific applications. Inconel fasteners are ideal for high-temperature and oxidizing conditions, Monel fasteners excel in marine and chloride-rich environments, and Hastelloy fasteners provide unmatched corrosion resistance in highly acidic or chemical-laden settings. By combining metallurgical expertise with cutting-edge manufacturing, Steelvron ensures consistent quality, dimensional accuracy, and reliable performance, making us a trusted supplier of nickel alloy fasteners worldwide.
