304 and 304L Stainless Steel Plate Stock Exporter in China

BBN Steel are professional Stainless Steel Plate Supplier in China,if you are looking for 304 material and 304L material Stainless Steel Plate,BBN Steel is definetly your best choice ever!

About 304 material and 304L material:

304 stainless steel is a common material, a density of 7.93 g / cm3, the industry alsoknown as 18/8 stainless steel. High temperature of 800 degrees, with good processing properties, high toughness characteristics, widely used in industrial and furniture industry and the medical industry food.

304L steel as a low C in the general state, its corrosion resistance and 304 similar, but after welding or stress after its excellent corrosion resistance to the grain boundary. In the case without heat treatment, can remain good corrosion resistance, generally use 400 or less (non-magnetic, temperature -196 degrees Celsius to 800 degrees Celsius). Widely used to produce good overall performance requirements (corrosion resistance and formability) of equipment and parts.

As we can see : 304L ratio of 304 carbon content, has a better corrosion.304 grade with higher strength, 304L with better better welding performance.

In general, the corrosion resistance of 304L stainless steel is similar to that of 304 stainless steel. However, the resistance to intergranular corrosion of 304L stainless steel is excellent after welding or stress relief.

According to the standard of hardness, 304 stainless steel is better than 304L stainless steel, because the carbon content directly affects the hardness of stainless steel.
