Hardness For SS-304 - Material engineering general

nickypaliwal (Materials) 26 Jan 17 07:05 If it is sour service then the criteria is 22HRC. In general, I have not come across any SS 304 material above that hardness range. You can check the hardness and if it is above 22HRC then need to explore more on acceptable range otherwise it should be fine. Heat Treating Process Parameters on a Martensitic Grade 420-Stainless steel has the highest hardness, 500 HV, among all the stainless steel grades with 0.15% Cabon, 12-14% chromium, 1% Manganese and Silicon. Martensitic stainless steels have high hardness and high carbon content. These steels are generally fabricated using methods that require hardening and stress relieving treatments. [1]
