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...

Stainless steel was first discovered by Harry Brearley, a British metallurgist, in 1913. Brearley developed a steel alloy with high resistance to corrosion, which eventually led to the creation of stainless steel.

There is an explanation of passivation and the use of passivation at PF Online Passivation of Stainless Steel. Try the guide to passivation of stainless steel at the British Stainless Steel Association. It discusses the use of nitric acid and citric acid treatments.
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.

When chromium is alloyed with steel, it produces stainless steel. Stainless steel is known for its corrosion resistance and various applications in industries such as construction, food processing, and medical devices.
Stainless steel tubing is typically manufactured by companies specializing in metal fabrication, such as Sandvik, Outokumpu, or Webco Industries. These companies utilize specialized equipment and processes to produce high-quality stainless steel tubing for various industrial applications.
Steel and stainless steel tend to weigh around the same, however, stainless steel can sometimes be a bit lighter.
