Structural applications often require welding to hold pieces of equipment in place. Since bars are used for structural purposes, it is important that they be suitable for welding such as grade Stainless Steel 304L Round Bar. Unlike grade 304, the low carbon version of the alloy works well in applications that require welding to be performed.
Lowering the content of carbon in ASTM A479 304L Stainless Steel Bar prevents sensitization at grain boundary precipitates. Therefore, it is possible for the end user to employ the 304l stainless steel bar in an as welded condition. Though the properties of grade 304 as well as alloy grade 304l stainless steel flat bar, tends to be similar, it is only because of the addition of nitrogen. The addition of nitrogen in the alloy is for two primary reasons. First, the austenite present in the microstructure of stainless steel 304L bar gets stabilized. Second, since the alteration of carbon lowers its mechanical properties, nitrogen not only improves the said properties, but the yield strength of the UNS S30403 Forged Bar also receives a boost. Despite not being able to be used at elevated temperatures for fear of susceptibility to intergranular corrosion, the Ss 304L Flat Bar works well in cryogenic temperatures, as they are able to maintain their excellent strength and toughness in such environments. Similar to grade 304, the 304L SS Hex Bar is used in applications that require price control.
