It is an iron-carbon alloy, which has a higher carbon content and a lower melting point than stainless steel. Carbon steel is similar in appearance and properties to stainless steel but has a higher carbon content.
Engineering and construction materials like carbon steel are commonly used in large-scale industrial processes, including telecommunications, transportation, chemical processing, and petroleum extraction and refining.
There are numerous kinds of steel that can be designated as Stainless Steel 304 Flanges, but all types of steel are made largely from iron and carbon using a two-step process. When chromium and nickel are added to stainless steel, corrosion resistance is achieved.
Forgings produced in grades A-105 are the first most common materials used to manufacture Pipe Flanges. For applications requiring lower temperatures, the A-350 LF2 material grades, while the A-694 Grades, F42-F70, are designed for high yields. Because of the increased strength of carbon steel flanges, high yield material is widely employed for pipeline service.
In addition to having more Chromium and Molybdenum than carbon steel flanges, alloy steel flanges are designed to withstand high temperature and high pressure environments. Because of the increased Chromium content, they have a stronger corrosion protection than conventional Carbon Steel flange.
In Flange manufacturing, Nickel, Chromium, and Molybdenum-containing stainless steel is the second most commonly used forge material. The most common ASTM A182-F304 / F304L and A182-F316 / F316L forgings are found in the A182-F300/F400 series. During melting, trace elements can be added based on the service needs of these Forgings classes. Aside from this, the 300 Series is not magnetic, whereas the 400 Series exhibits magnetic properties and is less corrosion resistant.
