ASTM A193 B6 fasteners are produced mainly from ferritic stainless steel, namely AISI Type 410, which has superior corrosion resistance and moderate strength. These fasteners have a tensile strength of minimum 110 ksi and yield strength of 85 ksi, along with high hardness and ductility for elevated temperature conditions. The composition of the material generally consists of chromium (11.5–13.5%), carbon (≤0.15%), manganese, silicon, and residual amounts of phosphorus and sulfur. These mechanical characteristics render ASTM A193 B6 fasteners applicable for high-pressure and high-temperature usage in diverse harsh industrial conditions.
