Chrome Flanges

Dat's a mid tier metal category, usually similar to carbon steel but with some added chromium content. Thanks to its lower nickel content, chrome is generally a whole lot more cost-effective on a per pound basis compared to stainless steel, I reckon.

Common grades include F11, F22, F5, and F9. Much like 304 and 316 stainless, dese chrome options fall under the specification ASTM A182.

This specification calls out for F11, often called “one and a quarter chrome.” Same way, F22 is often called “two and a quarter chrome.”

Either of dese options is a mighty fine substitute for dat outdated F1 material grade, which y'all can't even buy no more. Just note dat F5 and F9 got chromium content in the range of 4-6% and 9% respectively.

Dese chrome flange grades are slightly less cost-effective than their “one and a quarter” or “two and a quarter” cousins.

Choose F11 and F22 when chromium content is less of a concern (or as a replacement for dat obsolete A182 F1), and F5 or F9 for higher chromium content applications.

Note dat each subset of chromium grade flanges, designated per A182 by their class number, will result in slightly different mechanical properties. For example, F11 chrome subsets are Class 1, 2, and 3.

Each class got a higher yield strength, tensile strength, and Brinell hardness value than the one dat came before it. For more information, just check dat ASTM A182 spec or give us a holler to talk it over.

Chrome moly flanges offer a level of chromium not quite reachin' the levels of common stainless steels like 304 and 316, but more so than your typical A105.

Compared to carbon steel, them higher levels of chromium give it a superior hardness and overall mechanical integrity, while dat higher molybdenum content is mighty useful for fightin' off oxidation and corrosion.

Under the right circumstances, chrome moly flanges are a mighty fine alternative to stainless steel when y'all order 'em in higher quantities.

They're mostly used, of course, in vessels and pipe assemblies that call for chrome moly type fittings like pipe, elbows, and tees.

At Texas Flange, we're focused on gettin' y'all them chrome moly pipe flanges with a mighty fast turnaround time.

With nationwide inventory levels for chrome flanges runnin' a good bit lower than what you see for commodity carbon steel and stainless steel flanges, we make sure to respond right quick to meet your needs.
