Abstract
Powder Metallurgy (P/M) offers a cost-effective and design-friendly option for the manufacture of stainless steel hot exhaust gas oxygen sensor (HEGO) bosses for automotive exhaust systems. The critical requirements for this application include high temperature mechanical strength, good corrosion resistance, weldability, machine-ability for thread tapping, and resistance to thread galling when exposed to temperatures as high as 1000°C (1832°F). Optimally processed P/M 400-series stainless steel oxygen sensor (HEGO) bosses meet these critical requirements, and are comparable to those made from wrought stainless steel, either cold headed or machined.
