|Title:||Fatigue Properties Of High Strength Bolts|
|Abstract:||The aim of this paper is to analyze fatigue properties of high strength bolts in different metallurgical conditions. M8 bolts with coarse threads were separated in seven groups, three manufactured with AISI 4135 steel and heat treated after the process of thread rolling with three tempering temperatures (TRBHT). Four groups manufactured with SCM 435H steel and same conditions. In one group, the threads were made after quenching and tempering (TRAHT). Metallographic analyses, tension, hardness, and fatigue tests were performed. All TRBHT groups presented same fatigue resistance. TRAHT group presented fatigue limit approximately 9% superior than other groups. © 2011 Published by Elsevier Ltd.|
