Dear Kunal,

Thank you very much for your question!
Spring steel JIS G 4801 has a tensile strength of about 206000 PSI.　At Tokai Spring, we use SUP10 JIS G 4801 (which is equivalent to 51CrV4). There is also material SKD4 (similar to AISI H21) (alloy tool steel, die steel).

If you have any other questions, please feel free to contact us anytime!
