I am currently testing different types of steel (mainly steels of grades 200s and 300s) for work, some of which have been hardened before to improve their mechanical properties.
But before I'm starting my project, I was wondering if anyone has a handy spreadsheet or something which says when steel starts to corrode, show signs of wear or which temperatures are critical for the material. And by that I of course mean untreated steels i.e. steels that have not been heat treated or anything. Then, I will compare these results to the steels that have been hardened. O
