Welding Articles : Weldabilty and Description of Ferrous Metals

a. General. A cast iron is an alloy of iron, carbon, and silicon, in which the amount of carbon is usually more than 1.7 percent and less than 4.5 percent. (1) The most widely used type of cast iron is known as gray iron. Gray iron has a variety of compositions, but is usually such [...]

a. General. High yield strength, low alloy structural steels (constructional alloy steels) are special steels that are tempered to obtain extreme toughness and durability. The special alloys and general makeup of these steels require special treatment to obtain satisfactory weldments. These steels are special, low-carbon steels containing specific, small amounts of alloying elements. They are [...]

a. General. A large number and variety of obtain high strength, high hardness, corrosion alloy steels have been developed to resistance, and other special properties. Most of these steels depend on a special heat treatment process in order to develop the desired characteristic in the finished state. Alloy steels have greater strength and durability than [...]
