304L, 304H & 304 Stainless Steel Tampa Steel and Supply

The Difference Between 304, 304L and 304H Stainless Steel. When it comes to variations between 304 and 304L stainless steel, the most essential thing to note is the latter’s greater immunity to intergranular corrosion. Intergranular corrosion is the cracking that can occur along grain boundaries of steel in the presence of tensile stress.

Type 304 and 304L Stainless Steel Explained

Jan 11, 2020 · Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion

304 / 304H - Rolled Alloys, Inc.

Dual certified 304/304H is used as a material of construction up to 1500°F. Slight scaling begins at about 1200°F. This is the 0.04% minimum carbon version of type 304 stainless. It has general corrosion resistance similar to the low carbon 304/304L. However, it is subject to carbide precipitation in the heat affected zone (HAZ) of welds.

304H ss - Miller Welding Discussion Forums

The L vs. H. Higher carbon stainless is designated with H. (.02 or so vs. .08-.1%). The higher carbon makes it more likely to form precipitation of chromium carbides at grain boundaries. Hence the need (sometimes) for annealing. Annealing involves 1900-2000 F and rapid cooling/quenching. Which personally sounds all wrong but that's what 'they' say.

The extra low carbon analysis of T-304L, which further restricts carbide precipitation during welding permits the use of this steel in corrosive service in the as-welded condition. T-304L is essential particularly where heavier sections are involved. T-304H is a modification with .04/.10 carbon and no nitrogen content.
