no it is'nt.cobalt is an element that is found in the earth and is mined.

Steel, Stainless steel, Electroplated nickel silver, Melchior, Stellite, Talonite-Cobalt based alloys, Titanium based alloys etc.
No; steel is an iron-carbon alloy. Stainless steel is an alloy of steel with chromium added. Stainless steel is usually 13-25% chromium (by weight).
Cobalt steel is a form of high-speed steel containing a significant proportion of cobalt. M-35 (5% cobalt) and M-42 (8% cobalt) are common cobalt steel alloys. See http://en.wikipedia.org/wiki/High_speed_steel

Yes, there is. You use a tungsten or cobalt coated drill bit for this.

steel is steel and there is nothing you can do about it even if it is stainless steel or it i not stainless steel it will rust
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.
No; steel is an iron-carbon alloy. Stainless steel is an alloy of steel with chromium added. Stainless steel is usually 13-25% chromium (by weight).
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.
