What Is SS304 Stainless Steel? A Kitchen Material Guide
Learn what SS304 stainless steel is and why it is the best grade for kitchen products. Compare SS304 vs SS201, SS316, and SS430. Food safety material guide.
Understanding Stainless Steel Grades
Not all stainless steel is created equal. The "304" in SS304 refers to a specific grade of austenitic stainless steel that contains 18% chromium and 8% nickel. This particular composition makes it the most widely used stainless steel in the food industry, and for good reason.
Why SS304 Is the Gold Standard for Kitchen Products
Corrosion resistance: The chromium content creates an invisible oxide layer on the surface that protects against rust, tarnish, and corrosion — even when exposed to water, acidic foods, and salt daily.
Food safety: SS304 is completely non-porous and non-reactive. It does not leach chemicals into food, absorb odors, or stain from spices and sauces. This is why hospitals, commercial kitchens, and food processing plants use SS304 exclusively.
Durability: It withstands extreme temperatures, repeated dishwasher cycles, and heavy daily use without degrading. A quality SS304 product can last decades.
SS304 vs Other Grades
- SS304 vs SS201: SS201 contains less nickel and more manganese, making it cheaper but significantly less corrosion-resistant. Avoid SS201 for food contact.
- SS304 vs SS316: SS316 adds molybdenum for even better corrosion resistance, but the improvement is marginal for kitchen use and not worth the price premium.
- SS304 vs SS430: SS430 is magnetic and less corrosion-resistant. It is used in cheap appliances but unsuitable for cutting boards.
Velgrina SS304 Products
All Velgrina Stainless Steel Cutting Boards use genuine food-grade SS304 steel. The Drain Cover and 3-in-1 Sink Drain also use SS304 for long-lasting corrosion resistance. When you see "SS304" on a Velgrina product, you know it meets the highest food-safety standards.
