The important metal used with iron to produce stainless steel is A. Aluminium B. Chromium C. Tin D. Carbon

Aluminium
Chromium
Tin
Carbon

The correct answer is B. Chromium.

Stainless steel is an alloy of iron with a minimum of 10.5% chromium. The chromium forms a chromium oxide layer on the surface of the steel, which is very resistant to corrosion. This makes stainless steel a very popular material for use in a variety of applications, including kitchen appliances, cutlery, and building materials.

Aluminium is a soft metal that is not very resistant to corrosion. Tin is a soft metal that is used to coat other metals to prevent them from rusting. Carbon is a non-metal that is used to make steel stronger.

I hope this helps!
