Boat shaft

Our preferred material for tail shafts is Temet 25. Temet 25 is a high strength duplex stainless steel alloy with excellent corrosion fatigue strength and outstanding corrosion resistance. Its use allows for a smaller diameter shaft to be used which cuts cost and weight. Temet 25 was developed by Teignbridge, after extensive research development and testing, when it was found that other high strength stainless steels suffered from corrosion defects and in particular crevice corrosion. After an extensive period of research and development, and prolonged testing, with various materials, Temet 25 was shown to possess the outstanding corrosion fatigue strength and corrosion resistance. Fatigue testing was carried out, for Teignbridge by Exeter University laboratories. It was also carried out by Lloyds Register of shipping. First introduced into the marine market by Teignbridge in 1990 it has become an industry standard, and the material of choice by the majority of boat builders.
