HEAT TREATMENT
Solution anneal 1010–1150 °C followed by rapid water quench to retain austenite; not hardenable by heat treatment. Sensitization avoided by low carbon or stabilizers (Ti/Nb).

PROCESSING PRECAUTIONS
Weld with low-carbon or stabilized filler (e.g., 316L, 347) to avoid sensitization; passivate after fabrication. Not hardenable, but work-hardens rapidly — use sharp tools and rigid setups. Avoid chloride contact for 304 in warm service; specify 316/317 for marine or aggressive media.
