Inconel 625 / Alloy 625 for Project-Specified Fasteners
Inconel 625, also commonly referenced as Alloy 625, is a nickel-chromium-molybdenum alloy that is often discussed for corrosion-resistant industrial fasteners and custom parts where the material is specified by project documents.
Alloy 625 can be considered for stud bolts, threaded rods, bolts, nuts, washers, special fasteners, fastener sets and drawing-based components when project requirements call for this material. Final material selection should be reviewed according to service conditions, corrosion media, temperature, mechanical requirement, standard and project specification.
Procurement Focus
- Confirm material designation and applicable standard
- Confirm product type, dimensions, thread and quantity
- Confirm nut and washer requirement for fastener sets
- Confirm certificate and inspection requirements before quotation
- Confirm application environment if material review is needed
