Choosing stainless-steel cookware can be confusing—especially when you see numbers like 304 and 430.
Both are stainless steels, but their performance is very different.
Here’s the simplest comparison for beginners.
■ Quick Comparison Table
Category SUS304 SUS430
Nickel Yes No
Corrosion Resistance Excellent Moderate
Magnetism Non-magnetic Magnetic
Heat Resistance Very stable Can warp under high heat
Durability High Moderate–High
Price Higher Lower
Best Use Cookware, bowls, plates Tongs, utensils, induction base
■ Why SUS304 Is Better for Cookware
Outstanding corrosion resistance
Premium-quality feel
Safe for everyday cooking
Less likely to warp under heat
■ Why SUS430 Is Useful
Budget-friendly
Magnetic → great for induction
Strong enough for utensils and handles
Lightweight and easy to maintain
■ How to Choose Quickly
Pots, pans, bowls, plates → Choose 304
Tongs, spatulas, ladles → Choose 430
Induction bottom → Usually 430 + aluminum + 304 layers
■ Easy Ways to Identify Steel
Magnet test → sticks = 430
Higher price → usually 304
Heavier and sturdier → 304
Clear material labeling → trustworthy brand
■ Conclusion
For most kitchens, the best combination is:
304 for cookware
430 for utensils
This offers great durability, safety, and cost-efficiency.
