Mild Steel Flanges Manufacturers


Mild steel is what many manufacturers, suppliers and distributors refer to as low carbon steel. Typically, the measure of carbon found in the chemistry of Mild Steel V Band Flanges ranges between 0.05% to 0.25% of the total weight. Content higher than that would classify as cast iron. Because it does not have more than two elements i.e. carbon and iron, technically these steels are not referred to as alloy steels. The lack of additional elements in the Mild Steel Flanges imparts the steel with different properties that would usually be associated with alloy or even stainless steels. A lower carbon content means that Mild Steel Blank Flanges is normally more ductile, machinable, and weldable, especially if compared to high carbon steels. However, it is also because of its lowered carbon content that it is nearly impossible to harden and strengthen the Mild Steel Slip On Flanges through heating and quenching the material. The low carbon content in this steel grade means that the material has very little carbon and other alloying elements, which would be required to block dislocations in its crystal structure.

This results in the MS Pipe Flanges exhibiting less tensile strength properties as opposed to high carbon and alloy steels. A higher level of iron and ferrite makes these components magnetic. Compared to most alloy steels and stainless steels, the cost of producing these Mild Steel Flanges is much lesser.
