When sourcing stainless steel flatware, the grade of steel is the most critical factor for durability and rust resistance. 18/10 stainless steel (18% chrome, 10% nickel) is the premium choice for high-end hospitality due to its superior luster and corrosion resistance. For mid-range retail, 18/0 stainless steel is a cost-effective alternative that is magnetic and suitable for casual dining, though it may lose its shine faster. Always verify the polishing grade; 'Mirror Polish' provides a high-end reflective surface, while 'Tumble Polish' is more economical for bulk cafeteria use.
