SS 347 / SS 347H. Stainless Steel 347 is similar to the 321 stainless steels in that it is often used as a stabilized alternative to Type 304. In the case of 347, however, the stabilizing agent is columbium. This metal intensifies 347's already present ability to withstand intergranular corrosion for maximum capabilities.
