Our advice
Choose 304 for most indoor, food-contact and mildly corrosive service. For chlorides (sea water, salt, some chemicals) move to 316. For heavy welding of thick sections, 304L avoids sensitisation.
Values are typical ASTM A240 limits for flat products and are for guidance only. Always refer to the mill test certificate supplied with the material.
