The main difference between A-193 B8M grade bolts and B8 grade is the material. b8M grade is made of 316 austenitic stainless steel, which is more resistant to corrosion. a-193 B8M grade Class 1 requires solution treatment, and Class 2 requires strain-hardening. a-194 Grade 8M nuts are used with A-193 B8M grade bolts.
A-320L7 and L7M grade bolts are typically used in low temperature environments from 45°C to -101°C and are typically mated with A-194 Grade 4/Grade 7 nuts.
