Mild Steel Flanges roughly contains between 0.05% and 0.25% of carbon by weight. Due to its low carbon content, the alloy is more malleable and tends to be well suited for welding. The lesser the content of carbon in any steel, the more weldable and machinable the alloy becomes. The low carbon content in the Mild Steel V Band Flanges also indicates that the alloy has very little carbon or other alloying elements required to block dislocations in its crystal structure. This, in turn, results in a lower tensile strength as compared to either high carbon steels or alloy steels. The alloy of Mild Steel Exhaust Flanges also has a high amount of iron, with a ferrite microstructure, thus, making it magnetic. The negligible presence of other alloying elements, is perhaps, what makes Mild Steel Blank Flanges relatively affordable when compared with other conventionally used alloy steels or stainless steel grades.
Mild steel belongs to a category of carbon steel grades that contains a low level of carbon in its alloy.
The combination of good toughness properties along with affordability, weldability, and machinability that make thes Mild Steel Slip On Flanges a very popular choice of steel amongst several buyers. Moreover, the ferromagnetic properties in conjunction with stiffness are the reason why MS Pipe Flanges are used for construction, automobiles as well as electrical equipment.
