What are the difference between stainless steel and ordinary steel?

Answer 1

Some stainless steel is non magnetic, like the 300 series which contains a good bit of nickel which makes this series non-magnetic, but the 400 series does not have nickel and are thus magnetic, so you cannot differentiate between this series of stainless and regular carbon steel using a magnet. If the sample in question rusts easily, then it's probably regular carbon steel, though there are some high carbon steels like D2 tool steel for example, which have a high enough percentage of chromium (D2 has 11% to 13% generally) which make them 'almost' stainless and thus they don't rust as easily as a high carbon steel like O1, which does not have enough chromium (.50%) too inhibit oxidation and thus it rusts quite easily. The only other means to tell whether you have stainless steel or regular carbon steel would be by performing a spark test which could tell you whether you have stainless or regular carbon steel or sending a sample out for metallurgical analysis.

Answer 2

Weight= mass*acceleration due gravitation, in short W=mg which means there is no specific weight of stainless steel, the more you take, the more it weighs. You take some of it and put it on a weight machine it would show the weight. Stainless steel doesn't come in a fixed shape, it depends on you how much you need. Again remember, the more you take, the more it weighs. Hope this helps.

Answer 3

Stainless is classified as any steel that contains a minimal of 13% chromium and is known for its corrosion resistance.

Answer 4

Stainless steel contains about 18% chromium taht forms a protective oxide layer at the top that prevents rust
