Product Detail
Product Introduction
Grade 2 flat washers distribute bearing load and protect mating surfaces in corrosion-resistant joints. Selection must define inside and outside diameter, thickness, flatness, bearing area, mating fasteners, surface condition and galvanic environment.
Product Specifications
| Product | Grade 2 Titanium Flat Washers | Material | Titanium Grade 2 (UNS R50400) |
|---|---|---|---|
| Product Form | Flat, split-lock or drawing-specific washer | Typical Inquiry Range | For M2 to M36 fasteners in typical inquiries; custom ID, OD and thickness by review |
| Dimensional References | ISO 7089/7090, DIN 125, ASME B18.21 or approved drawing | Threads / Dimensions | Metric coarse or fine, UNC, UNF or drawing-specific as applicable |
| Surface | Machined and cleaned; lubricant, anti-galling treatment or coating by agreement | Documents | MTC, heat/lot traceability and dimensional inspection report |
| Inspection | Dimensions, thread gauging, surface and agreed functional or mechanical tests | Supply Basis | Approved purchase order, invoked standard and drawing |
Typical inquiry ranges are not a stock guarantee. Final manufacturability, tolerances and test requirements are confirmed against the complete RFQ.
Selection and Configuration
- Geometry: Specify ID, OD, thickness, edge form and dimensional tolerance.
- Bearing function: Confirm available bearing area, mating-surface strength and permitted surface marking.
- Joint compatibility: Review bolt and nut material, lubrication, temperature and galvanic exposure.

Chemical Composition – Titanium Grade 2
Maximum weight percent unless shown otherwise; titanium is the balance.
| N max | C max | H max | Fe max | O max | Residual each / total | Ti |
|---|---|---|---|---|---|---|
| 0.03 | 0.08 | 0.015 | 0.30 | 0.25 | 0.10 / 0.40 | Balance |
Mechanical Properties – Grade 2 Material Reference
| Property | Annealed Grade 2 Material Reference Minimum |
|---|---|
| Ultimate tensile strength | 345 MPa (50 ksi) |
| 0.2% yield strength | 275 MPa (40 ksi) |
| Elongation | 20% |
Material values do not automatically establish finished-fastener loadability. Finished-part acceptance depends on geometry, manufacturing route, condition and the expressly invoked fastener specification or drawing.
