DIN2093 Conical Heavy Disc Springs Washer-A B C Type Quenching Treatment Cone Dish Gasket

description

1. High-Energy, Fatigue-Resistant Spring Performance
   • Hot-formed from 60Si2MnA alloy spring steel, then oil-quenched at 850 °C and tempered to 42–48 HRC, each cone delivers a consistent load–deflection curve with spring-rate tolerances held to ±10 %.
   • A single washer stores up to 260 kN · mm of elastic energy (Type C, Ø200 mm); stacking in series or parallel permits custom travel or force profiles from a few newtons to several thousand kilonewtons.
   • Shot-peened surfaces introduce compressive residual stress that lifts endurance life beyond 2 × 10⁶ cycles at 75 % of maximum deflection—ideal for shock, impact, and thermal-cycling joints.
   • ≥ 12 µm electro-zinc plus trivalent passivation shields the steel for 120 h neutral salt-spray (ISO 9227); optional clear, yellow, black, olive, or custom RAL/Pantone top-coats push corrosion resistance past 1 000 h and provide quick visual coding.
2. Wide-Ranging Industrial Applications
   • Power Generation & Turbomachinery: Maintains bolt preload on turbine casings, tower flanges, and gearbox covers subjected to vibration and fluctuating temperatures.
   • Oil, Gas & Chemical Processing: Live-loads pump and valve gland followers, ensuring leak-free sealing during pressure and thermal swings.
   • Mining, Construction & Off-Highway Equipment: Absorbs impact loads in excavator booms, crusher drives, and suspension pivot points where downtime is costly.
   • Precision Engineering & Robotics: Provides compact, high-force springs in overload clutches, press tools, and servo-axis tensioners without adding bulky coil springs.
3. Installer-Friendly, Space-Saving Handling
   • Chamfered inner and outer edges prevent scoring when sliding over studs or into counterbores; orientation marks guide rapid series/parallel stacking without gauges.
   • Substitutes directly for flat washers—standard torque values can be retained while the spring action automatically compensates for joint relaxation, gasket creep, or thermal expansion.
   • Slim height-to-load ratio (deflection up to 0.4 × t) delivers high forces in confined spaces, often eliminating the need for belleville stacks or hydraulic tensioners.
   • Delivered loose, in shrink-wrapped columns, or tape-on-reel for robotic feeders; optional PTFE-free dry-film lubricant cuts installation friction and galling on automated lines.
4. Certified Quality & Long-Term Durability
   • 100 % laser scanning verifies thickness ±0.02 mm, cone angle ±0.25°, parallelism ≤0.05 mm, and free height ±0.1 mm; Cp/Cpk ≥ 1.67 data archived for ISO 9001, IATF 16949, and AS 9100 audits.
   • Post-forming stress-relief temper removes residual stresses, preserving ductility for repeated disassembly and re-stacking during service.
   • Duplex-coated variants (zinc + epoxy powder) withstand 1 000 h xenon-arc weathering and 200 °C bake cycles without flaking or colour shift—suitable for outdoor, offshore, and mildly chemical environments.
   • QR-coded packaging links every lot to melt chemistry, heat-treat parameters, coating bath, and load-deflection charts, ensuring traceable compliance for safety-critical aerospace, medical, and infrastructure projects.
