Stainless Steel Pressure Riveting Screws: Technical Overview and Applications1. Definition and CharacteristicsStainless Steel Pressure Riveting Screws are specialized fasteners combining the installation efficiency of rivets with the removable/reusable capability of screws. These components feature:Material Composition: Typically manufactured from AISI 304 (1.4301) or AISI 316 (1.4401) stainless steel, providing ≥18% chromium and 8-10.5% nickel content for superior corrosion resistance.Mechanical Properties: Yield strength ranging 205-310 MPa (304) to 240-310 MPa (316), with tensile strength between 515-690 MPa (304) and 515-620 MPa (316).Surface Finish: Standard finishes include Ra 0.8-1.6μm mechanical polish or electropolished surfaces reducing friction coefficients to μ=0.15-0.20.Temperature Resistance: Continuous service from -200°C to +800°C (304) and -200°C to +1000°C (316) in oxidizing environments.Installation Parameters: Require 3-12 kN axial force for proper setting, creating 0.2-0.5mm material deformation for optimal joint integrity.The unique M4-M12 thread sizes combined with 6-20mm grip ranges allow these fasteners to accommodate material stack-ups from 0.5mm sheet metal to 12mm composite panels while maintaining ≥90% thread engagement.2. Application Scenarios2.1 Transportation IndustryIn rail vehicle manufacturing, these screws withstand EN 12663-1 dynamic loads while providing:Vibration resistance up to 50Hz frequency at 5g accelerationFatigue life exce
