This compression spring is made of stainless steel 302 wire and has an outside diameter (OD) of 0.12 inch and a wire size of 0.014 inch. This stainless steel 302 wire spring meets American Society for Testing and Materials (ASTM) A313 or Aerospace Material Specifications (AMS) 5688 spring temper. It is a general purpose material offering mechanical properties with greater corrosion and heat resistance than music wire. The spring ends are closed and ground (squared) for efficient transfer of force, and a reduced risk of tangling. This spring has a load capacity of 1.02 pounds, and a maximum operating temperature of 500 degrees F (260 degrees C). It is slightly magnetic and passivated for added corrosion resistance.
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.
