Stainless Steel 304L Flanges

Grade 304L is a chromium-nickel based austenitic Stainless Steel alloy. This alloy is known to have increased levels of resistance against several chemical compounds such as alkaline solutions, acidic ad neutral solutions. Due to the addition of molybdenum in the chemistry of the alloy, the corrosion resistance property of 304L Stainless Steel Flanges is much higher than that of the stainless steel grade 304. The molybdenum content is what permits Stainless Steel 304L Flanges to be more resistant to corrosion overall, with specific resistance properties against chlorine pitting. Alloy 304L, or as known by manufacturers as marine grade flanges are also found to be more applicable in areas with high or elevated temperatures compared to other stainless steel grades. The ASTM A182 F304L Flanges has more resistant to heat as compared to grade 304. However, most of the properties possessed by grade 304L tend to be similar to many of the same general characteristics as that of stainless steel alloy 304.

The corrosion resistance property of A182 Grade F304L WNRF Flange is particularly effective against chemicals, such as the ones used in industries like the paper and textile industry. This stainless steel flange also finds use in applications involving the food processing equipment, chemical processing, as well as the medical industry. While this stainless steel grade is pliable under hot working and cold working techniques, the alloy cannot be work hardened with heat treatment. And, in general, the UNS S30403 Slip On Flange is considered to have lower weldability compared to the other grades i.e 304LL and 304LTi stainless steels. However, the SS 304L Blind Flange is still preferred over the other stainless steel alloys in terms of workability.
