This compression spring is made of stainless steel 302 wire and has an outside diameter (OD) of 1.225 inches and a wire size of 0.085 inch. The stainless steel 302 wire springs meets American Society for Testing and Materials (ASTM) A313 or Aerospace Material Specifications (AMS) 5688 spring temper. The spring ends are closed and ground (squared) for efficient transfer of force, and reduced risk of tangling. This spring has a load capacity of 12 pounds, and a maximum operating temperature of 500 degrees F (260 degrees C). This stainless steel 302 compression spring meets ASTM A313 or AMS 5688 for quality assurance, and it is more resistant to corrosion than music wire springs.
Compression springs are open-coil helical springs that are used to save space and absorb shock in a variety of applications. They absorb the energy of a force acting upon them by becoming shorter, store that energy while compacted, and expand as they release the energy. These springs are either placed over a rod, or fitted inside a hole, and are found in a wide variety of applications ranging from automotive engines and large stamping presses to major appliances and lawn mowers, medical devices, cell phones, electronics, and sensitive instrumentation devices.
