Incoloy 825 fasteners

Incoloy 825 fasteners (UNS N08825) are premium nickel-iron-chromium-molybdenum-copper alloy components designed for superior corrosion resistance in severe chemical and marine environments.

With 38-46% Ni, 19.5-23.5% Cr, 2.5-3.5% Mo, and 1.5-3% Cu, these fasteners offer tensile strength of 655-800 MPa, yield strength ?220 MPa, 30% elongation, density 8.14 g/cm³, and melting point ~1400°C. They resist pitting, crevice corrosion, chloride stress cracking, and acids like sulfuric/phosphoric, maintaining stability from cryogenic to 540°C.

Available as hex bolts, nuts, screws, washers, studs, and threaded rods per ASTM B425/ASME SB425, in sizes M3-M56 (3/16"-2"), lengths 3-200mm, with DIN/ISO/ANSI standards, plain/zinc/passivated finishes, and torque ratings (e.g., 1/4" lubricated: 5.8-6.6 ft-lb)
