65Mn Spring Steel Plate Sheet 0.5mm~5mm Thick Shim Plate Sheet 100mm/200mm Wide

Material Characteristics

High-Carbon Manganese Alloy Steel: Manufactured from premium 65Mn spring steel (GB/T 699 standard) with 0.62%-0.70% carbon content and 0.90%-1.20% manganese, ensuring superior elasticity and fatigue resistance.

Precision Cold Rolling Process: Thickness tolerance within ±0.02mm with polished/zinc-coated surfaces, achieving corrosion resistance grade ≥8 for outdoor applications.

Dual-Phase Heat Treatment: Quenching + medium-temperature tempering process yields HRC 45-52 hardness and ≥1200MPa tensile strength, optimizing elasticity and wear resistance.

Performance Advantages

Extended Service Life: 300% longer durability than conventional spring steel, with deformation rate <0.5% after 100,000 fatigue cycles.
Energy Efficiency: 210GPa elastic modulus enables 92% energy recovery efficiency for high-frequency vibration equipment.
Vibration Dampening: Unique grain structure reduces resonant frequency by 40%, effectively minimizing mechanical noise.

Usage Precautions

⚠️ Processing: Preheating to 150℃ required during laser cutting to prevent cracking; carbide tools recommended.
⚠️ Storage: Maintain relative humidity <60% and avoid contact with acids/alkalis.
⚠️ Safety Warning: Minimum bending radius must be 6x material thickness to prevent internal stress cracks.

Application Scenarios

▸ Industrial: Automotive suspension springs, heavy machinery dampers, high-speed rail fasteners
▸ Electronics: Printer paper feeder levers, smartphone SIM card ejectors
▸ Military: Firearm firing mechanisms, UAV landing gear shock absorbers
