Built to industrial standards for durability and strength: quenched manganese steel strips are heat-treated to resist wear and maintain shape under repeated high loads, extending service life in demanding environments. Reliable high-load performance: engineered to deliver consistent mechanical properties under heavy stress, reducing downtime and part replacement frequency. Size format: dimensions are given as Width × Length × Thickness. Length = 500 mm. (Please confirm width and thickness when ordering to match your application.) Material and function: quenched manganese steel provides toughness and fatigue resistance for use as coil springs, flat springs, and other spring elements. Spring steel backing plates can be welded effectively to form robust, integrated assemblies. Versatile compatibility: suitable for a wide range of spring and flat-spring designs, and compatible with electrical components and steel gauge applications where resilient spring action and dimensional stability are required. Fabrication-friendly: good weldability of spring steel backing plates allows secure joins and simplifies assembly into larger structures without compromising spring performance. Quality assurance: manufactured to meet strict industrial durability and strength criteria, helping ensure predictable behavior in production and field use. Typical applications Coil and flat springs in machinery and suspension components where long fatigue life is required. Spring contacts, retainers, and other resilient parts in electrical assemblies and switchgear. Precision steel gauges, measuring fixtures, and backing plates that require welded integration into frames or housings. Why choose this product Delivers long-term performance under high load conditions. Offers material toughness and weldability for durable, integrated constructions. Clear sizing convention (W × L × T) with a 500 mm length for easy specification and ordering.
