1.inconel625 LIMITING CHEMICAL  COMPOSITION, %

2.inconel625 Introduction

A nickel-chromium-molybdenum alloy with  an addition of niobium that acts with the  molybdenum to stiffen the alloy’s matrix  and thereby provide high strength without a  strengthening heat treatment. The alloy resists  a wide range of severely corrosive environments  and is especially resistant to pitting and  crevice corrosion. Used in chemical processing,  aerospace and marine engineering, pollutioncontrol equipment and nuclear reactors.
