<p>① strong carbide forming elements such as vanadium, titanium, niobium, zirconium and the like. Such elements as long as there is enough carbon, under appropriate conditions, to form the respective carbides; only in the lack of carbon or high temperature conditions, until an atomic state into the solid solution.<a href="">half round stainless steel bar</a>

<p>② carbide forming elements, such as manganese, chromium, tungsten, molybdenum and the like. Part of such elements by atomic state into the solid solution, another part of the formation of substitutional alloy cementite, such as (Fe, Mn) 3C, (Fe, Cr) 3C, etc., if the content exceeds a certain limit (except manganese), turn form their carbides such as (Fe, Cr) 7C3, (Fe, W) 6C and the like.<a href="

<p>③ elements do not form carbides, such as silicon, aluminum, copper, nickel, and cobalt. Such elements are generally present in an atomic state austenitic, ferritic and other solid solution. Alloying elements in some of the more active elements, such as aluminum, manganese, silicon, titanium, zirconium, etc., easily and steel oxygen and nitrogen together to form a stable oxide and nitride, generally in the form of inclusions present in the steel in. Manganese, zirconium and other elements also formed sulfide and sulfur. Different types of metal compounds can be formed when the steel contains a sufficient amount of nickel, titanium, aluminum, molybdenum and other elements. Some alloying elements such as copper, lead, if the content exceeds its solubility in steel, places than pure metal phase.<a href="">Galvanised Steel Finish</a>
