Solution

steel is also known as mild steel and the difference between stainless steel and mild steel are as follow:

Stainless Steel is less malleable and harder than mild steel.
Mild steel s less brittle than stainless steel.
Mild Steel is more resistant to corrosion.
Mild steel can be further strengthened through the addition of carbon.
The basic difference is that stainless steel has very little carbon and is alloyed with chromium, nickel, molybdenum and other elements to improve its mechanical and chemical properties.

Stainless steel differs from carbon steel by amount of chromium present. Carbon steel rusts when exposed to air and moisture. Stainless steel is not very magnetic, and is fairly brittle when compared to regular steel.

Some stainless steel is magnetic while some is not. There are many different types of stainless steel, as alloy steel with at least 10.5% chromium is considered stainless steel. Steel is composed mostly of iron, which is a ferromagnetic material.So steel is magnetic in nature and some stainless steel are magnetic while some are not.

The300 series stainless steel contains Chromium and Nickel which makes this steel non-magnetic but the400 series steel contains just chromium which makes this type magnetic,
