Q: I have a high temperature exhaust stream that is part of an air-to-air energy recovery system that experiences temperatures around 1300F consistently and can go up to 1500 intermittently. I need to ensure that the bolts have a tensile strength of 130ksi. Can you help me out with this?
A: Yes we can. The way to ensure your A286 bolts meet the tensile strength required you should request that the bolts are quoted to the specification ASTM A453 Grade 660 (A, B, C or D). This specification applies to bolts, studs, nuts and other fasteners. It ensures that the A286 bolt you receive will meet specific tensile and stress rupture properties.
