1.4306:

1.4306 is an ultra-low carbon austenitic stainless steel developed to solve the serious intergranular corrosion tendency of the material caused by the precipitation of Cr23 and C6 under some conditions. Its resistance to intergranular corrosion in the sensitized state is significantly better than that of 304, and its performance is the same as that of 304 except that its strength is slightly lower. It can be welded by various common stainless steel welding processes, and heat treatment is not required after welding.
