Why 347h SS is used for Chemical Processing?

The grade 347 is specific austenitic stainless steel made for repeated intermittent exposure to temperatures above 800 degrees Celsius. These are modifications of 304 stainless steel. They are similar to the 321 grade in some mechanical properties but different in that it has columbium in the composition. The material is corrosion resistant to most corrosive media in medium to high temperatures.

 

This is an important aspect required at chemical processing. The material has minimum yield strength of 205MPa and the minimum tensile strength at 515MPa. This allows the material to withstand high pressure at temperatures above 850 degrees Celsius. The pipes and components also have a good elongation and high hardness. The 304 material can undergo intergranular corrosion above temperatures 850 F. The 347H has a higher carbon content and heat resistant so that it can perform in this temperature range.

 

The combination of the pressure containment capacities, the strength, hardness, heat resistance and corrosion resistance make it applicable for chemical processing. These properties also make the material used in other high corrosive, high heat applications such as the boiler tubes and casings, radiant super heaters, heat exchanger tubes, oil and gas refineries and aircraft exhaust stacks.
