This listing is for a single piece of 65Mn blue temper annealed spring steel sheet, designed for DIY CNC processing. It combines the toughness and elasticity of spring steel with machinability and a blue temper finish for wear resistance and easy handling. Key benefits elasticity and fatigue resistance typical of spring steel, suitable for small springs, clips, and resilient components. Blue tempered and annealed finish provides a balance of hardness and formability, improving wear resistance while remaining easy to machine. Good machinability for DIY CNC projects, including cutting, drilling, bending, and shaping with common workshop tools. Finishes and dimensions are suitable for precise fits in jig plates, fixtures, and prototyping assemblies. Key attributes Material: 65Mn spring steel Treatment: blue tempered and annealed Thickness range: 0.5–2.5 mm (per product spec) Actual item size: 0.8 mm thick x 20 mm wide x 500 mm long Quantity: 1 piece Purpose: optimized for DIY CNC processing and related fabrication tasks Use cases Create custom CNC jig plates, fixtures, or clamping components that require spring steel's elastic properties. Fabricate small springs, resilient clips, or loadbearing latches for hobbyist or prototype projects. Use in model making or enclosures where a durable, bendable sheet with controlled hardness is advantageous. What to expect in use Easy to cut, drill, and bend with standard metalworking tools; deburr edges after cutting. The blue temper finish provides some corrosion resistance and a nonreflective surface, aiding handling and alignment in assemblies. While offering good wear resistance, it is not a substitute for heavy duty industrial spring components; suitable for DIY and prototyping workloads. Notes This item is a single piece with dimensions 0.8 mm x 20 mm x 500 mm. The thickness listed in the product range (0.5–2.5 mm) refers to the general specification of the series. Store in a dry environment to maintain surface condition.
