Thanks to their corrosion resistance and high strength, stainless steel containers are widely used in settings ranging from kitchens to industrial environments.
304 Stainless Steel (Top Choice): Contains 18% chromium and 8% nickel; offers excellent corrosion resistance. It is the preferred food-grade option for daily household and dining use, offering great value for money.
316/316L Stainless Steel (Premium Choice): Features added molybdenum compared to 304, providing superior resistance to acids, alkalis, and chloride corrosion. It is suitable for long-term storage of soy sauce, vinegar, or brine, as well as for outdoor use, though it comes at a higher price.
Avoid 201 Grade: While inexpensive, it has high manganese content and poor corrosion resistance. Prolonged contact with acidic foods can cause heavy metals to leach out; it is not recommended for use as a food-contact container.
Check for Markings: Always verify that the product or packaging bears a clear steel grade stamp (e.g., SUS304, 18/8) and a "food-contact safe" symbol; vague terms like "premium quality" alone are unreliable.
