Stellite 6 pump shaft sleeve bushings heat resistance, wear resistance

Introduction

Stellite alloy is a range of cobalt-chromium alloys designed for wear resistance. It is a completely non-magnetic and corrosion resistant cobalt alloy. There are a number of Stellite alloys, with various

compositions optimised for different uses.Some are formulated to maximize combinations of wear resistance,corrosion resistance, or ability to withstand extreme temperatures.

Stellite 6 is the most widely used cobalt base alloy and exhibits good all-round performance. It has excellent resistance to many forms of mechanical and chemical degradation over a wide temperature range, and retains a reasonable level of hardness. Particular attributes are its outstanding self-mated anti-galling properties (which result in its wide use as a valve seat material), its high temperature hardness, and a high resistance to impact and cavitation erosion. The alloy is ideally suited to a variety of hard facing processes. It has less tendency to crack than Stellite 12 in multiple layers, but is more wear resistant in abrasion and metal-to-metal or galling conditions. It can be turned with carbide tooling. Stellite 6 is used on valve seats and gates; pump shafts and bearings, erosion shields and rolling couples. It is often used self-mated.
