ASTM A193 Grade B8 is 304 stainless steel. Class 2 bolts are solution treated and then strain hardened, which raises their strength well above Class 1 stainless bolts while keeping the corrosion resistance of 304. Minimum strength depends on diameter:
| Diameter | Min. tensile strength | Min. yield strength |
|---|---|---|
| Up to 3/4″ | 125 ksi | 100 ksi |
| Over 3/4″ to 1″ | 115 ksi | 80 ksi |
| Over 1″ to 1 1/4″ | 105 ksi | 65 ksi |
| Over 1 1/4″ to 1 1/2″ | 100 ksi | 50 ksi |
Values per ASTM A193. Confirm design values with the Engineer of Record.
