- Application of A193 B8 Cl. 2 Fasteners
ASTM A193 B8m Class 2 Bolts have a high tensile strength as well as good corrosion properties which are inherited from the austenitic nature of the alloy. A193 B8 Class 1 specified Fasteners manufactured from this grade of austenitic stainless steel can be treated with carbide solution. Carbide solution treatment, also known as solution annealing, is a process where the fasteners like the ASTM A193 Gr B8m Studs or stainless bars are first treated by heating followed by water quenching. This ensures that the Sa193 B8 Cl.1 gains maximum corrosion resistance.
ASTM A193 B8m Nut is strain hardened after being treated to a solution of carbide. This solution treatment done on the A193-B8 Cl.2 helps them to achieve increased strength characteristics. Treating the A193 B8 Cl1 to carbide solution also reduces the potential for galling.
