Types of Flanges
SPECIALIZED MILD STEEL FLANGES MANUFACTURER, LOW CARBON MILD STEEL FLANGE
Kapoor Forge is leading manufacturers, Suppliers, and Exporters of Mild Steel Flanges. Mild Steel Flanges roughly contains between 0.05 and 0.25 of carbon by weight. Due to low carbon content, the alloys are more malleable and tend to be well suited for welding. The lower 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 veritably little carbon or other alloying fundamentals required to block dislocations in its clear structure. This results in a lower tensile strength as a compared to either high alloy steel, carbon steel. The alloy of Mild Steel Exhaust Flanges also has a high quantum of iron, with a ferrite micro-structure, therefore, making it magnetic. The negligible presence of alloying element, Mild Steel Flanges are fairly affordable when compared with conventionally used stainless steel, or alloy steel grades.
We are ISO Certified Manufacturer and Stockist of Mild Steel Flanges ANSI 150, Table D & Table E Mild Steel Flange, Series A & B Mild Steel Blind Flange, Low Carbon Mild Steel Lap Joint Flange, MS Ring Type Joint Flange, PN10 PN16 MS Orifice Flange Pressure Rating, Mild Steel Threaded Flange at Reasonable Price.
