Short answer: Food and beverage plants use 316L stainless for product-contact surfaces and 304 where duty is mild, finished and passivated for cleanability, with copper alloys limited to permitted conductive parts, all specified to food-grade standards.
At a Glance
Why 316L for Contact
316L is the default for product-contact surfaces because it is cleanable, weldable and low-carbon for safe passivation; the grade choice is in our 316 vs 316L 그리고 304 vs 316 comparisons, and the equipment view in our Food Beverage Equipment Guide.
Finish and Passivation
Surface roughness and passivation decide cleanability, so electropolished and passivated finishes earn their keep; our Surface Treatment Guide 그리고 Passivation Guide cover the requirements, with options in our Finishing Options.
Where Copper Is Used
Copper appears only in permitted conductive parts such as heat-exchanger tube, never in direct food contact; the comparison is in our Galvanized vs Stainless guide and the base metal in our Copper Supplier range.
Washdown and Corrosion
Washdown environments are corrosive, so grade and coating must suit the cleaner; our Corrosion Resistance Guide 그리고 Degreasing Guide cover prep and care.
Sourcing Food-Grade Stock
Buyers specify alloy, finish (Ra), and food standard, then require full mill certification; our How to Choose a Metal Supplier 그리고 Mill Test Certificate Guide frame the RFQ.
