Alloy 36 (also known as Cronifer 1925 hMo) carries the designations UNS N08926, EN 1.4529, and meets ASTM B649/ASME SB 649 specifications. It’s formulated with 24–26% nickel, 19–21% chromium, and 6–7% molybdenum, plus copper (0.5–1.5%) and nitrogen (0.15–0.25%). This unique chemistry gives you exceptional resistance to pitting, crevice, and chloride stress-corrosion cracking, outperforming traditional 316 or 904L stainless steels

You’ll find Dalloyed’s Alloy 36 fasteners excel in chemical processing, oil & gas, marine, power generation, and phosphoric-acid plants. They keep piping, heat exchangers, and pressure vessels leak-free—even in seawater and sour-gas service—across a broad temperature window from –196 °C up to +400 °C. Beyond 400 °C, you should consult us for guidance, as long-term strength gradually decreases.

When you choose Alloy 36 nuts, bolts, washers, or stud bolts from Dalloyed, you benefit from our full traceability: mill-test certificates, third-party inspections, and compliance with DIN EN 10088-2, ASTM B649, and NACE MR0175/ISO 15156. Every fastener ships with documentation so your global projects meet local regulations—whether in the USA, Germany, Japan, UAE, or beyond.

To maximize strength, Alloy 36 is delivered solution-annealed (1,120–1,170 °C) and water-quenched, locking in its superior toughness and ductility. If your application demands higher yield, we can supply cold-worked and aged variants that push ultimate tensile strength above 600 MPa and yield strength near 300 MPa.

Our Alloy 36 fasteners are precision-machined to tight tolerances. We offer standard metric and imperial sizes, with custom finishes—passivation, bright dip, or specialized coatings—to extend service life in abrasive or highly corrosive settings. Dalloyed’s global logistics network ensures your order reaches you quickly and securely.

Benefits of Alloy 36 Fasteners (Made Simple)

• Very strong against rusting in tough spots like corners and tight spaces
• Stands up well to salty environments, including sea water and chemicals
• High strength – handles heavy loads without bending or breaking
• Works well in both very cold (–196 °C) and hot (up to 400 °C) conditions
• Won’t rust easily in acids or near the ocean
• Non-magnetic, so it’s safe for sensitive equipment
• Easy to weld using common welding materials
• Lasts a long time and needs very little upkeep

At Dalloyed, you rely on Alloy 36 fasteners across the world’s most demanding industries. You’ll find our nuts, bolts, washers, and stud bolts securing critical assets chemical processing plants, oil & gas refineries, marine and offshore platforms, power generation facilities, and phosphoric-acid production units. We customize each fastener to your application, whether you need extra corrosion resistance in sour-gas service or exceptional strength at cryogenic or elevated temperatures.

Our Alloy 36 range meets all major international standards—UNS N08926, EN 1.4529, ASTM B649/ASME SB 649, DIN EN 10088-2, and NACE MR0175/ISO 15156—and comes in every form you require: hex bolts, socket screws, hex nuts, lock nuts, plain and spring washers, threaded rods, and custom stud bolts. With Dalloyed’s global logistics, you can count on timely delivery to any location, from the USA, Germany, Japan, and the UK to the UAE, Australia, Brazil, and beyond.
