5pcs Blackened 65Mn Steel Compression Springs, Wire Diameter 2mm, Outer Diameter 19mm, Length 60mm, 2x19x60mm(5pcs)

The current spring size is: wire diameter 2mm, inner diameter 15mm, outer diameter 19mm, height 60mm, and the number of springs in the package is 5 Material: 65 Manganese steel, a medium carbon spring steel with a high manganese content. After heat treatment, internal stress is eliminated, and it has a high elastic limit and tensile strength. The working temperature is less than 200℃ Surface treatment: The spring surface is blackened to improve the cleanliness of the spring surface, good corrosion resistance, and long service life End surface treatment: The two ends of this spring are ground flat to increase the contact area between the spring and the support surface, prevent uneven force from causing eccentric load or lateral bending, reduce stress concentration, and facilitate installation and positioning Application scope: Widely used in automobiles, tools, hardware products, home appliances, DIY manufacturing, industrial machinery and equipment, etc., such as automobile leaf springs, clutch reeds, brake springs, mechanical valve springs, plunger pump springs, punch buffer springs, washing machine shock absorber springs, etc.
