Which is better, 304 or 420 stainless steel?
Normally, grade 420 stainless steel has a tensile strength of around 586
MPa—high, but not higher than grade 304 stainless steel (621 MPa). However, when hardened and stress relieved, grade 420
stainless steel has a tensile strength of 1,586 MPa, nearly three
times as strong as it is when annealed.

Stainless Steel Bar Application:
What are the weaknesses of 304 stainless steel?
304 stainless steel has excellent resistance to a wide range of
atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments and to
stress corrosion cracking above about 60 °C (140 °F).
