Since the Galvanized Carbon Steel C21 High Hub Flange has been coated by a thicker layer of zinc on its surface, these flanges are known to be corrosion resistant. In fact, the Galvanised Carbon Steel C21 Flange is much more corrosion resistant as opposed to a flange which has been surface plated with zinc, because the coating of zinc on the surface of C21 Flange achieved through galvanization is much more thicker, thereby proving to be more resistant.

What is C21 Flange?


C21 Flange

While this Steel Low Carbon C21 Blind Flange is low in terms of strength, and cost; the alloy exhibits other properties such as High ductility, toughness, good machinability as well as good weldability. Typically, Low content Carbon Steel Grade C21 Forged Flange is soft and the alloy cannot be hardened by heat treatment. Hence, hardening this low carbon containing Fully Killed Carbon Steel BLRF C21 Flange can usually be achieved by cold work.

On heating, High Carbon Steel C21 Weld Neck Flange becomes extremely hard and brittle. Further, high carbon alloy based ASTM C21 Slip On Flange, is very difficult to cut, bend and weld. Steel High Carbon C21 Lap Join Flange is also referred to as carbon tool steel, by several of our clients.

Medium Carbon Steel C21 Screwed Flange tend to be much stronger as well as more difficult to form, weld and cut in comparison to low carbon grade flanges. Although medium grade carbon steel flanges are stronger than their low carbon containing counterparts, the properties of the former such as ductility and toughness are often compromised. Medium grade C21 Carbon Steel Pipe Flanges can quite often be hardened followed by which they can be tempered using heat treatment.
