Stainless steel 347/1.4550/S34700 by Yuhong Group is quiet similar as stainless steel 321. it stabilizing agent is columbium, which make it different with 321. As the same time, the 347 often used as a alternative to 304 stainless steel. The content of the columbium make the 347 allows maximum capabilities of intergranular corrosion. And also give the 347 ability to undergo the repeated heating in the temperatures up to 1650°F(898.89°C). It is widely use in the high temperature equipment.
