304 SS Precision Coil for Flexible Hose Metal Bellows 0.1mm 0.2mm 0.3mm Fatigue Grade
Product Spotlights
Product Description:
This 304 stainless steel precision coil is specifically engineered for flexible hose and metal bellows applications, available in ultra-thin thicknesses of 0.1mm, 0.2mm, and 0.3mm with fatigue-resistant properties for repeated flexing cycles. The material offers excellent cyclic performance, maintaining integrity under continuous bending and vibration. Typical applications include flexible metal hose inner and outer plies, expansion joint bellows, vibration absorber elements, flexible couplings, pump connectors, flexible exhaust connectors, HVAC flexible ducting, and any application requiring thin-gauge stainless steel capable of withstanding repeated flexing without fatigue failure.
