Question

Why is steel magnetic?

Answer 1

Answer:

Basic stainless steels have what's known as a “ferritic” structure, which enables them to be magnetic. ... It's the addition of chromium that leads to the ferritic structure. This, plus the addition of carbon, hardens the steel and qualifies it as a martensitic steel. Stainless steel knives are typically martensitic.

Answer 2

Basic stainless steels have what’s known as a “ferritic” structure, which enables them to be magnetic. Remember the chromium content? It’s the addition of chromium that leads to the ferritic structure. This, plus the addition of carbon, hardens the steel and qualifies it as a martensitic steel. Stainless steel knives are typically martensitic.
