1.4306 stainless steel seamless

1.4306 is an ultra-low carbon austenitic stainless steel developed to solve the problem of severe intergranular corrosion tendency of 304 material due to the precipitation of Cr23 and C6 under some conditions. Its intergranular corrosion resistance in the sensitized state is significantly better than that of 304. Except for slightly lower strength, other properties are the same as 304. It can be welded with various general stainless steel welding processes, and no heat treatment is required after welding.

1.4306 is a low carbon austenitic stainless steel, also known as 304L stainless steel. Because of its good corrosion resistance, high temperature strength and good processability, it is widely used in food, medical equipment, chemical industry, papermaking, shipbuilding and other industries.
