Valve Seat

Introduction

WD-Co 6 is the most widely used of the wear resistant cobalt-based alloys and exhibits good all-round performance. It is regarded as the industry standard for general-purpose wear resistance applications, has excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range, and retains a reasonable level of hardness up to 500°C (930°F). It also has good resistance to impact and cavitation erosion. WD-Co 6 alloy material is ideally suited to a variety of hardfacing processes and can be made to investment casting & P/M components. WD-Co 6 casting valve seats are widely used in oil and gas industry.
