As a trusted manufacturer with 6+ years of expertise in high-alloy fasteners, we specialize in custom-engineered Inconel 625 flat washers that redefine reliability in extreme environments. Our washers merge the unparalleled corrosion resistance of Inconel 625 (UNS N06625) with precision-machined custom dimensions, tailored to your exact project requirements. Backed by ASTM/ASME compliance and ISO 9001 certification, we deliver solutions that outperform standard washers in aerospace, oil & gas, and chemical processing—ensuring zero leakage, long-term durability, and cost savings on maintenance.
1. Product Overview
Our customized Inconel 625 flat washers are circular load-distribution components crafted from nickel-chromium-molybdenum superalloy, designed to eliminate fastener-induced surface damage and enhance assembly stability. Unlike off-the-shelf options, we offer full dimensional customization—from micro-sized washers for aerospace engines to heavy-duty variants for offshore platforms—all adhering to global standards like DIN 125, ISO 7089, and ASME B18.22.1. The Inconel 625 alloy’s unique composition forms a protective oxide layer, resisting corrosion from seawater, sulfuric acid, and chloride ions even at temperatures up to 2000°F (1093°C).

3. Material Properties (Inconel 625)
The superior performance of our washers stems from Inconel 625’s exceptional characteristics:
• Chemical Composition (key elements):
Ni (≥58%), Cr (20–23%), Mo (8–10%), Nb (3.15–4.15%), Fe (≤5%)
• Mechanical Strength:
Tensile Strength: ≥965 MPa; Yield Strength: ≥415 MPa; Elongation: ≥30%
• Environmental Resistance:
◦ Withstands cryogenic temperatures to 2200°F
◦ Resists pitting, crevice corrosion, and oxidation
◦ Unaffected by seawater and industrial chemicals
