There is no danger in using 304 at ambient teperatures. sulfudation starts above 300C. It is negligible below that.

Mcguire is correct. Also, nickel can consume 15% percent its own volume in hydrogen as it approaches high temperatures. Which can lead to further problems.

Just don't weld it unless it is dual stamped 304/304L. Welding will cause sensitization unless an "L" grade is ued, and can lead to polythionic stress corrocsion cracking
