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. 
On the use of Rockwell hardness testing hardness of stainless steel, stainless steel pipe standard generally provides for HRC and HRB two rulers. For the annealing stainless steel usually corresponds to each grade stainless steel varieties provides hardness values should not be HRB certain a large value, typically 88-96HRB range.

This process is followed by cooling at 30°C for an hour and air-cooling. Sub-Critical Annealing - Grade 416 steel is heated to 650 to 760°C and air-cooled. Hardening This process involves heating grade 416 steels to 925 to 1010°C, oil quenching and tempering to improve mechanical properties.

Martensitic stainless steel. Martensitic stainless steel mainly contains 12~18% Cr, and the amount of C can be adjusted according to needs, generally 0.1~0.4%. For tools, C can reach 0.8~1.0%, and some are to improve the stability of tempering resistance by adding Mo, V,and Nb etc. Steel hardness vs yield or ultimate strength? Physics ForumsMay 15, 2018 · It is possible that steels of various compositions and processing histories will deviate in hardness-tensile strength relationship from the data presented in this table. The data in this table should not be used for austenitic stainless steels, but have been shown to be applicable for ferritic and martensitic stainless steels.
