Please tell me about spring materials.
There are piano wires (such as SWP), oil tempered wires (such as SWO), and spring steel (such as SUP) in the classification of spring materials. Where is SAE9254 material classified? What kind of material is SAE9254 made from? Is it related to the American automobile standard (SAE standard)? Thank you.
SAE9254 is a SAE (Society of Automotive Engineers) standard material.
(JIS symbol is SUP12.)
Therefore, it will be classified as spring steel!
