Product Description
Inconel 686 Fasteners: Superior Corrosion-Resistant Solutions
Looking for Inconel 686 Fasteners that deliver exceptional performance in extreme environments? You've found the right partner. Our high-quality fasteners are engineered from premium Inconel 686 (UNS N06686) alloy, offering outstanding resistance to both oxidizing and reducing acids. With 14+ years of manufacturing excellence, TSM Technology provides reliable fastening solutions for your most demanding applications. Whether you need standard bolts, custom studs, or specialized washers, our products meet international standards while ensuring long-term reliability in harsh chemical environments.
What are the products?
Our products are premium-grade nickel-chromium-molybdenum-tungsten alloy components designed for superior corrosion resistance. These fasteners contain high levels of molybdenum (15-17%) and tungsten (3-4.4%), making them ideal for environments where standard stainless steel fails.
The unique composition creates a dense passive film that protects against pitting, crevice corrosion, and stress corrosion cracking. This makes them perfect for chemical processing, marine applications, and pollution control equipment.

Production and Processing Technology
Our manufacturing process combines advanced metallurgy with precision engineering. We start with premium raw materials that undergo strict chemical composition verification.
The production begins with vacuum induction melting, ensuring uniform alloy distribution. Hot forging shapes the initial fastener forms, followed by precision machining to achieve exact dimensions.
Heat treatment at 1150-1200°C solution anneals the fasteners, optimizing their corrosion resistance properties. Final processing includes thread rolling for superior thread strength and surface finishing.
Quality control occurs at every stage, with real-time monitoring ensuring consistent performance. Our automated systems track each batch from raw material to finished product.
What is the production process of the products？
- Step 1: Raw Material Inspection - Chemical composition verification and mechanical property testing.
- Step 2: Melting and Casting - Vacuum induction melting ensures clean, homogeneous alloy structure.
