What is the hardness of carbon steel?
The hardness of carbon steel can vary greatly. It depends on the carbon content, the presence of other elements, and the conditions under which it was made. Was it forged or rolled out? And was it tempered or heat treated in any way? Lots of considerations here. Steel, that is, carbon steel can come in a number of "flavors" from rebar for concrete to tool steel.

What is the basic difference between CS and IT?
*Carbon steel, also called plain carbon steel or "Mild Steel", is steel where the main alloying constituent is carbon. The AISI defines carbon steel as: "Steel is considered to be carbon steel when no minimum content is specified or required for chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect; when the specified minimum for copper does not exceed 0.40 percent; or when the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60. If it crosses limit as said, it will come under alloy steel. ASTM A 106 gr B is a carbon steel pipe and seamless Pipe for High Temperature Service. So, it will be a mild steel comes under carbon steel category.
Which electrode is used to weld stainless steel to stainless steel?
It depends on the type of stainless steel. Stainless steels come in various compositions and are identified by numbers and letters. Electrodes should be chosen that match these. For example when welding 316 stainless use type 316 electrodes. In a lot of situations you can safely use the next higher number. 304 stainless can be welded with 308 electrodes, 308 stainless with 310 electrodes. 309 electrodes are generally used to weld stainless to carbon steel.

The Basics of Welding Rods?
Welding rods are a crucial element of the welding process. In some circles, they are referred to as filler metals. For those who are unaware, a welding rod is a metal that is used during the welding process to connect to joints to one another either during repair manufacture of metal products. In most cases, the way that welding occurs is when the work pieces are partially melted and a filler metal, usually in the form of a welding rod, is used in order to form a liquid pool that joins the two parts together. When the metal solidifies, it creates a strong joint. A welding rode may also be referred to as an electrode. In most cases, they come in four different types. One of these types is the covered welding rod. The coating of the rod usually consists of calcium fluoride, iron powder, cellulose, and rutile. Rods that are coted in rutile typically give the weld a much nicer looking appearance that is very solid and high in quality. In some cases, a stainless steel rod may be used in order to weld two steel pieces together. In gas welding, bare welding rods are used instead. Several deoxidizing metals are included such as aluminum, silicon, titanium, and manganese. These are used in order to keep oxygen out of the process, which can cause the metals to rust and corrode during welding. Other materials such as titanium and zirconium may be included in order to prevent nitrogen from reacting with the metals as well. In most cases, these rods come with thicknesses somewhere between 2.4 and 0.7 millimeters. The thickness of the rod will depend on the metals that are being used, and for what purpose. A tubular welding rod, which comes in the form of a wire, is used in what is referred to as flux-cored arc welding. Another type of welding rod are the welding fluxes, which are used in submerged arc welding. This is a process that requires a constant supply of both solid and tubular welding rods. These four types of welding rods can be divided up into fast-fill electrodes and fast-freeze electrodes. Fast fill electrodes melt rapidly, while fast-freeze electrodes solidify quickly.
