The best characteristic of grade 316 is its corrosion resistance, specifically in marine environments. As an austenitic stainless steel alloy, the material is ductile, which makes it easier for a manufacturer to shape different bolt heads and form threads. In comparison to other stainless steel classes, those belonging to the austenitic type, specifically A193 Gr B8m Material have better resistance to corrosion in various media.
The creep resistance properties of this alloy are significantly higher than that of grade B8. Moreover, their tensile properties are a notch higher due to the inclusion of molybdenum in its alloy. In environments, particularly those that contain chloride ions, the alloy exhibits good overall resistance to corrosion. The primary concern in such environments is that chloride ions tend to rapidly corrode the component. Despite that, the ASTM A193 Grade B8M Bolts can resist the effects of both crevice corrosion and corrosion caused due to pitting. Even at moderately high temperatures, the corrosion resistance properties, tensile strength, and mechanical properties of the Astm A193 Grade B8M Hex Bolts are considered to be far superior to austenitic stainless steel alloy grade - 304. As an alloy that contains molybdenum, the toughness of the SA193 B8m Stud Bolts is much more superior to carbon steel alloys and to the conventionally used fasteners in grade B8. A combination of its excellent properties and its resistance to oxidation, marine environments make the ASTM A193 B8m Nut a very popular grade in the market today, especially in comparison to the economically feasible grade 304. Though it is priced on the higher side, the higher content of nickel included in its chemistry makes it possible for the Grade B8m Bolts to be used across a wide range of applications.

The utilization of this grade is invaluable to a few high temperature applications, particularly since the ASTM A193 Grade b8m bolt is a demonstration of properties like higher creep and better pressure to crack. Besides, the ASTM A193 B8M Nuts can likewise show a higher rigidity at raised temperatures.
