Specification ASTM A193 not only covers alloy steel grades but also those alloys that belong to the austenitic class, such as grade 347. Grade 347 is an austenitic stainless steel alloy, that may be referred to as grade B8C. with good resistance to general corrosion, the A193 B8c Class 1 Material is an alloy that has been stabilized with the inclusion of both columbium and tantalum in its chemical composition.
One of the benefits of using this alloy is that ASTM A193 Grade B8C Bolts have exceptional resistance to heat. And hence, they can withstand high temperatures without losing any of their mechanical properties. It is common for alloys to experience failure at temperatures between 800°F – 1500°F. At temperatures as high as this, metals lose their dimensional integrity and have become weak. Here the chromium present in steel alloys would form chromium carbide precipitates, which in turn would sensitize the grain boundary to cause intergranular corrosion. However, since the carbides present in the alloy of Astm A193 B8C Hex Bolts do not form precipitates, they have excellent resistance to intergranular corrosion. In environments where oxidation is a common cause of failure, the ASTM A193 Grade B8C fasteners would resist corrosion even at elevated temperatures. Moreover, for the alloy to sustain itself in such conditions, it needs to have higher creep strength as well. Since the creep strength of the SA 193 B8C Screw and the oxidation resistance is high, these fasteners do well in the petroleum refineries, where they may be used in applications involving highly corrosive polythionic acid. The alloy exhibits resistance to polythionic acid SCC or stress corrosion cracking in the presence of a hydrocarbon (petroleum industry) service.
