Stainless Steel for Cookware & Kitchen Equipment
Cookware plants need coil that draws consistently, not just nominal chemistry. 304 is the premium food-contact baseline, 430 supplies magnetic induction layers, and selected 201 serves controlled budget applications.
Corrosion and Failure Mechanisms
- Splitting, wrinkling or excessive earing during deep drawing
- Surface pickup and scratches through forming and polishing
- Localized corrosion from salt retention or unsuitable cleaning
- Delamination or poor heat transfer in incorrectly specified multilayer bases
Common Selection Risks
- Buying to chemistry alone without draw ratio and trial-coil criteria
- Treating 430 magnetic base material as equivalent to a 304 food-contact body
- Ignoring crown, thickness tolerance, grain and surface protection

Frequently Asked Questions
What do 18/8 and 18/0 mean?
They describe nominal chromium and nickel: 18/8 commonly indicates 304-type material, while 18/0 commonly indicates 430.
Why does induction cookware use 430?
Ferritic 430 is magnetic and couples with an induction field.
What is deep-drawing quality coil?
It is produced for stable forming, controlled grain and limited earing to reduce tearing and trim scrap.
