304L Stainless Steel Flanges

The lower carbon content in SS 304L Slip On Flange helps to minimize or to eliminate carbide precipitation, which can occur during the welding process. This, in turn, permits the Stainless Steel UNS S30403 Flange to be used in an as-welded condition, even when they are exposed to severely corrosive environments. If the more conventional alloy grade 304 stainless were used in the same way, it would degrade much faster in comparison to A182 F304L Flange at the weld joints. ASTM A182 F304L specified flanges need to meet the requirements chemically as well as mechanically for this particular standard.

Simplistically speaking using SS 304L Blind Flange can eliminate the requirement to anneal weld joints prior to using the completed metal form, thereby proving to be a time and effort saving alternative.

Although Stainless Steel 304L Flanges are similar to its parent alloy i.e. stainless steel grade 304, there very little difference between both of them. Hence grade 304 & its derivative i.e. SS 304L Flanges can be dual certified. The difference between these two grades of stainless steel is the content of the element carbon present in them. In the case of alloy grade 304L, the content of carbon is lower in comparison to grade 304. This difference of 0.05% in the content of carbon is what produces a slight, yet a marked, difference in the performances of these two stainless steel alloys. This being said, alloy grade 304L would be structurally weaker as compared to the traditional 304 components.
