Stainless Steel 304L

Stainless Steel 304L (Core 304L)

(UNS S30403) (EN 1.4307)

Core 304L/4307 is a low-carbon alternative to Core 304/4301. The lower carbon content minimizes carbide precipitation as a result of heat input, for example during welding, giving improved resistance against intergranular corrosion. It’s suitable for a wide variety of applications that require good formability and weldability, and can be delivered with a variety of surface finishes.

Core 304L/4307 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family.The austenitic CrNi standard grades are the most widely used group of stainless steels. Their well-balanced material properties make them suitable for the fabrication of many products.
