Food Grade SUS316L Stainless Steel Strips Thickness 0.8mm 1.0mm 1.2mm 1.5mm Application for Kitchenware

1. Introduction​

SUS316L stainless steel strips, recognized as a premium food-grade material, are specifically engineered for kitchenware applications requiring exceptional corrosion resistance, hygiene, and durability. With precise thickness options (0.8mm, 1.0mm, 1.2mm, 1.5mm) and a low-carbon composition (L-grade), these cold-rolled strips offer superior formability and weldability while meeting strict international food safety standards.​

2. Chemical Composition (Weight %)​

​

​

The addition of molybdenum (Mo) enhances resistance to chloride-induced corrosion (e.g., from salt, vinegar, or seawater), making it ideal for harsh kitchen environments.​

• Hygiene: Free from harmful heavy metals (e.g., lead, cadmium) per food contact regulations​

6. Applications in Kitchenware​

6.1 Core Uses​

• Cutlery & Utensils: Knives, forks, spoons, and tongs (resistant to food acids and detergents)​

• Cookware: Pan bodies, lids, and handles (excellent heat distribution and anti-rust properties)​

• Sink & Drainage Systems: Durable against constant water exposure and abrasive cleaners​

• Oven & Grill Components: Racks, trays, and heating elements (耐高温 up to 800°C in continuous service)​

• Cabinet & Storage Solutions: Hinges, drawer slides, and shelf brackets (long-lasting in humid environments)​

6.2 Advantages for Kitchen Applications​

• Food Safety: Non-toxic, non-reactive surface that won’t leach chemicals into food​

• Easy Maintenance: Smooth finishes resist food residue buildup and are simple to sanitize​

• Aesthetic Versatility: Available in multiple surface finishes to match modern or traditional kitchen designs​

• Mechanical Reliability: High ductility allows for deep drawing (e.g., forming sink basins) and precise stamping​

7. Processing Considerations​

• Weldability: Excellent results with TIG, MIG, and laser welding (use 316L filler wire to maintain corrosion resistance)​

• Formability: Suitable for bending, stamping, and roll-forming without cracking (even at minimum thicknesses)​

• Heat Resistance: Maintains mechanical properties at temperatures up to 450°C, with reduced scaling at higher temperatures
