WebNov 25, 2024 · ABSTRACT. This book discusses the technology of high-temperature bolting materials and the design considerations of high-temperature bolted joints. It is based on the second international conference on high-temperature creep resistant materials held in York. WebAfter 300 C the preload in such bolts can be expected to decrease to a very low level. In applications requiring greater resistance to stress relaxation, bolts are frequently specified to the ASTM A193 standard. Covered in this standard are alloy and stainless-steel bolting materials for high temperature applications.
