Is nitriding cookware safe?Updated 3 months ago

Yes, nitriding has been used for over a hundred years in a variety of industries, including surgical tools and medical devices, and it is completely safe for cookware use.

1. It’s a Surface Hardening Process, Not a Coating
— Nitriding changes the outer layer of the metal itself by diffusing nitrogen into it.
— Unlike nonstick coatings (like Teflon), there’s no risk of chemicals flaking off or leaching into food.
— Because the surface is stable and non-reactive, it doesn’t contaminate food—even acidic dishes like tomato sauce or citrus-based marinades.

2. No Harmful Additives
— The process doesn’t introduce toxins, heavy metals, or synthetic materials.
— Once complete, there’s nothing “on” the cookware to wear off or react with your food.

3. High Heat Stability
— Nitrided surfaces can easily withstand high temperatures, making them much safer than synthetic nonstick coatings, which can degrade above ~500°F.
