Grade 304 is considered to be one of the most widely used grades because it is very economical and very easily available. As an austenitic stainless steel grade belonging to the 300 series family, its chemical composition can be changed to meet the requirements. For instance, if welding piping systems is a priority, its chemical composition can be changed by lowering the content of carbon. Low carbon containing alloys such as the Stainless Steel 304L Flanges are less likely to remain vulnerable to intergranular corrosion.
In a typical high carbon stainless steel alloy, the oxygen present in the air intensifies the formation of carbide precipitates. The newly formed carbide precipitates generally sensitize the grain boundary making this particular stainless steel grade to become vulnerable to decay. But since the content of carbon in the SS UNS S30403 Weld neck flange is already reduced, it does not permit the formation of precipitates, and thus directly sensitization of the stainless steel grains even when treated to elevated temperatures during applications like welding. Another advantage of having low carbon content is that all conventional welding methods may be used on these DIN 1.4307 Pipe Flanges. This makes it easier to form joint weld connections across several industries. In particular, this alloy is used in the petroleum industry. For instance, in petroleum refineries, the temperatures often reach elevated heights, which in turn is cause for corrosion. And where conventional carbon steel would exhibit signs of failure, the alloys that work well in such conditions would be the ANSI B16.5 SS 304L Plate flange. To ensure better functionality, strength, and durability, most stainless steel grades are made into components using specifications such as the Astm A182 F304l Blind Flange.
