General Characteristics
304L/4306 is a higher nickel alternative to 304L/4307 with improved formability and deep drawability.
304L/4306 is an austenitic stainless steel that belongs to the standard CrNi stainless steel family.
304L/4306 has the variant with 10.5 wt.% nickel for improved formability and low carbon content for improved resistance against intergranular corrosion after welding.
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.
304L/4306 is commonly available from many stainless steel stockists in manyproduct forms and dimensions. It can be supplied with a wide range of functional and aesthetic surface finishes.
