What material is this stainless steel fruit tray made of?
pyein’s stainless steel fruit trays are manufactured using high-quality 304 stainless steel (also known as 18/8 stainless steel), which contains 18% chromium and 8% nickel. This is the industry standard for food-contact surfaces and is widely recognized as safe by the FDA under 21 CFR Part 177.
Why 304 Stainless Steel?
304 stainless steel is the most commonly used food-grade stainless steel globally. Its 18% chromium content forms a passive layer of chromium oxide on the surface, making it highly resistant to rust, corrosion, and staining — even after repeated washing in commercial dishwashers.
The 8% nickel content enhances the material’s durability and gives it a bright, polished finish that maintains its appearance over years of use. Unlike 430 stainless steel (which contains no nickel and is magnetic), 304 is non-magnetic and offers superior corrosion resistance.
At pyein, we source our raw materials from ISO 9001-certified suppliers and conduct regular composition testing to ensure every batch meets the 304 grade specification.

Real-World Case
A 5-star hotel chain in Dubai replaced their previous 430 stainless steel fruit trays with pyein 304-grade trays after experiencing rust spots within 6 months. After switching to pyein, the same trays showed zero corrosion after 18 months of daily buffet service and commercial dishwasher cycles.
