Manufacturing Specification	Washers are typically stamped or machined from Hastelloy C276 plate/sheet (ASTM B575) or rod (ASTM B574). Dimensional tolerances strictly follow DIN 125, DIN 9021, or ASME B18.22.1.
Types Available	Flat Washers (Form A / Form B), Spring Lock Washers, Belleville Washers, Machined Washers, and Custom Punched Washers.
Properties & Applications	Essential for distributing load evenly across fastener joints in highly corrosive environments. Provides a vital secondary degree of resistance against galling and galvanic corrosion in chemical processing equipment, scrubbers, and reactors.
Marking	Due to size constraints, flat washers are generally not permanently marked unless specifically requested by the client or required by a custom specification.
Qualification & Acceptance	Independently tested for hardness, chemical analysis, pitting resistance, and supplied with EN 10204 Type 3.1 Material Test Certification.
