WebOct 23, 2001 · Grade 304 is a standard "18/8" stainless. It is the most versatile and most widely used stainless steel available, even though a wide range of alternatives are available; and has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing. WebJul 28, 2024 · A relatively light, 15 kgf load is applied to case hardened parts treated to achieve a minimum effective case depth 0.007 inches or a total case of 0.012 inches. Other Rockwell variants (HR30N and HR45N) apply slightly higher loads on parts with incrementally higher minimum effective or total cases.
