Thoughtfully designed cookware for everyday cooking.

Short answer:
Both are excellent for cookware, but 316 stainless steel offers higher corrosion resistance and durability.

304 stainless steel is the most widely used material for cookware and kitchen tools.

316 stainless steel contains an additional element called molybdenum (Mo), which improves resistance to salt, acid, and corrosion.

This means 316 stainless steel is especially ideal for:

• cooking salty or acidic foods

• humid or coastal environments

• long-term durability

304 is already great, but 316 is our premium choice for cookware designed to last a lifetime.

Yes — we recommend a quick first cleaning.

During the polishing process, a small amount of fine polishing residue may remain on the surface.

Before first use:

1. Wipe the surface with a small amount of cooking oil using a paper towel.

2. Wash with mild dish soap and a soft sponge.

3. Rinse thoroughly and dry completely.

This simple step helps remove polishing residue and prepares the surface for cooking.

After the first cleaning, you can use the cookware normally.

Chefwin cookware uses a traditional polishing process performed by skilled technicians.

This method helps ensure:

• a more even and durable surface

• better performance for high-heat cooking

• long-term durability in real kitchen environments
