What is 304 Surgical Stainless Steel?
The 304 Surgical Stainless Steel contains about 18% chromium and 8% nickel
in addition to the iron.
The popularity of 304 surgical stainless steel is due to its gleaming
appearance which lasts for the life of a product with just an occasional
cleaning. Its excellent corrosion resistance is due to an invisible,
passive oxide film that forms on the metal's surface in air.
304 Surgical Stainless Steel is sometimes referred to as T304.
Hospitals use surgical stainless steel because it can be kept clean
and sterile.
Advantages of 304 Surgical Stainless Steel
Corrosion Resistance
Temperature Resistance
Flavor Protection
Economy
Durability
Cleanability
Design Flexibility
Beauty
Layers allow even heat flow, and durability. The aluminum conducts heat well in the inner layers, but is not desirable
on the outside because it corrodes and comes off in the food. Stainless
steel protects the food and the cookware itself. Stainless steel
also contains iron which makes it good for magnetic induction stoves.

Compare stainless steel and aluminum cookware:
Steel is clean and durable, Aluminum can enter food; it pits and scrubs off.
Aluminum as a toxin
Compare stainless steel and teflon cookware
Steel is clean and durable, Teflon coating comes off into food and scrubs off,
so it doesn't last and is not healthy.

Special Cover Design (water seal)
The snug fit allows cooking with much less water, so moisture
is retained in the food.

"Low Heat" Minimum Moisture Cooking
Energy Efficient
You can cook on top of the stove (on Low) many things that
used to require using the oven, so it reduces your power consumption.
