Overview

As a leading supplier & manufacturer in India, RAHUL FERROMETAL supply cost-effective Incoloy 864 Products.

INCOLOY® alloy 864 (UNS S35135) was specifically developed for automotive exhaust system flexible couplings, EGR tubes, manifolds and tailpipes. It exhibits excellent fatigue resistance, thermal stability and resistance to hot salt corrosion, pitting and chloride stresscorrosion cracking. INCOLOY alloy 864 is covered by U.S. Patent 5,827,377.

Corrosion Resistance

INCOLOY alloy 864 was first developed as a corrosion-resistant material specifically for automotive exhaust systems. Most of the data presented in the following pages relate to that area of application. However, the alloy’s potential for other, non-automotive, applications is of sufficient interest to pursue laboratory test programs in other media. Iso-corrosion charts for INCOLOY alloy 864 in hydrochloric and sulfuric acids are presented at the end of this section.
