Regular steel will "hold" a magnet. Some types of stainless steel will also hold a magnet strongly. I have several knives as well as swords of which some are made out of stainless steel and some are made out of high carbon steel which all hold a magnet equally as strong. If the steel in question rusts easily then that is a telltale sign that the object in question is probably made out of regular carbon steel. The only other means to differentiate between the two is a 'spark' test which can tell you whether you have stainless steel or carbon steel, otherwise sending a sample out for metallurgical analysis is the only other way to find out whether you have stainless steel or regular carbon steel.
Stainless Steel is used because it has an higher corrosion resistance over normal steel.
Stainless steel can be differentiated from regular steel by its higher resistance to corrosion and rust due to the presence of chromium. Regular steel does not have this added chromium content, making it more prone to rusting.
nothing because it is steel is steel
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
You can differentiate between a stainless steel spoon and a silver spoon by examining their weight and appearance. Stainless steel is typically heavier and has a matte finish, while silver is lighter and has a shinier appearance due to its high reflectivity. Additionally, you can perform a magnet test as stainless steel is magnetic whereas silver is not.
The newer stainless steel refrigerators have better circulation of heat. They also do not get dirty looking or scuff up as easily as normal refrigerators.
Stainless steel is not significantly soluble in water under normal conditions. However, prolonged exposure to certain corrosive environments, such as acidic or saline water, can lead to some degree of dissolution or corrosion of stainless steel.
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
Well, the answer lies in the question; by saying 'real' stainless steel, you are implying that there are fake metals which go under the name 'stainless steel', thus the difference is that the stainless steel in refigerators is actually stainless steel, and the fake stainless steel is not...thus your question is answered...
No, Stainless steel is not porous. Steel how ever is.
stainless steel
Not at all it has about the same strength as normal steel (by thickness and weight); it just does not rust (or as quickly) due to the addition of Nickle to the steel.
