Yes, need one between the two dissimilar metals.

MS pipe refers to mild steel pipe and ERW pipe is electric resistance welding pipe. The difference is ERW is made of very fine hard steel, while MS (black pipe) is made of malleable steel.
Seventy-five percent of diamonds that are mined are used in industry. These diamonds are not gem-quality stones, and appear cloudy, even milky because of their flaws and inclusions. 'Black diamonds', properly Carbonado, are gem-quality stones. You can read more, below, and depending on whether you want to employ your 'black industrial diamond' as a gem stone or as an industrial tool, you can pay accordingly.

from what i can gather, which isn't alot:Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills.Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale. The surface is then washed to remove the acid and a light oil added to prevent rusting.Mild steel sheet is manufactured generally in two grades, cold rolled and hot rolled.Hot rolled mild steel sheet is the initial product produced by the steel mill as a downstream process prior to further processing such as cold rolling.Hot rolled mild steel sheet has a mill scale which is usually black in colour. Hence the common name Black Mild Steel Sheet. Black mild steel sheet is commonly used in fabrication shops, it is more economical than cold rolled mild steel sheet.Black mild steel sheet will usually require more preparation work prior to any finishing system being applied.Cold rolling is done to:Reduce the thicknessImprove the surface finishImprove the thickness tolerancesTo offer a range of "tempers"As a preparation for surface coating

Brass and steel are compatible, Otherwise we could NOT use brass valves with steel piping.
No, brass cannot be used as a dielectric union between copper and black iron pipe. Dielectric unions are typically made of materials that are not electrically conductive, such as plastic or rubber. Brass is a conductive material and would not provide insulation against galvanic corrosion between copper and black iron pipe.
stainless steel do not turn black. anything black in them is removable. After cleaning they are good as new. Stainless steel, as its name implies, does not stain or oxidize. If you have a utensil that is turning black, it might very well be silver or silver plated. Silver does durn black or tarnish as it oxidizes. If you are certain the item is stainless, something is going on that is out of the ordinary.
Stainless steel dishwasher are more expensive that white or black models.

Certainly, if the pipes are kept dry, and don't carry an electrolyte, such as water.Otherwise, it's a bad idea to directly connect different metallic pipes. In fact, most plumbing codes prohibit such a connection.That's because anytime any two dissimilar metals contact each other -- while in the presence of an electrolyte -- whichever metal has the higher electropotential will corrode, through electrolytic action.So, in the case of copper vs iron, the copper side of the joint will eventually fail due to corrosion -- unless you electrically isolate the two metals.You can do this via a dielectric union, or dielectric nipple. Or, you can use a hardened brass fitting, which resists corrosion and also smooths the dielectric potential between the copper and steel.Of course, another author may have a different opinion (like the one below.) So my advice is to understand the 'why' of electrolytic corrosion, so you can determine whether or not, in your case, a dielectric union is advisable.####Of course , NO Problem and there are many ,many options of doing so.The electrolytic conditions happens when connecting ferrous metals to non ferrous metals that contain zinc (galvanized) if you think about it EVERY SINGLE CAST IRON RADIATOR has a brass shut off valve, Most black steel gas line have a BRASS gas valve. Brass bolts are the best way to go when installing CAST IRON ROOF DRAINSAlso why use a dielectric union when there are dielectric nipples less chance of leakage
No, all of them come in black or stainless steel

The appliances are all the same, except for their color and, perhaps, the texture of the outside. Stainless to me looks lighter and less heavy in a room, but that is a trend that may be passing. If you have a bright kitchen, then black may work out. Pricing for both may be higher than that for white or bisque.
