1.4307 is a super low carbon austenitic stainless steel developed to solve the serious tendency of intergranular humus corrosion in some conditions caused by the precipitation of Cr23 and C6 of 304 material. Its sensitized state resistance to intergranular corrosion is significantly better than 304, except the strength is slightly lower, other properties and 304. All kinds of stainless steel welding process can be used for welding, after welding can be done without heat treatment.
