Incoloy 865(UNS S35115)

1.Incoloy 865 INTRODUCTION

INCOLOY alloy 865 (UNS S35115) is an  economical, high-performance corrosionresistant alloy. Developed from the technology  of INCOLOY alloy 864, it improved strength,  ductility and fatigue resistance at reduced  cost. The alloy was designed for automotive  applications such as flexible couplings and  exhaust gas recirculation (EGR) components.  However, with its excellent combination of  strength and corrosion resistance, alloy 865  may be evaluated for chemical processing and  marine applications.
