ALLOYED 13 CHROMIUM STEEL UNS S41427 FOR COMPLETION EQUIPMENT AND TUBING - CORROSION TESTS IN SIMULATED WELL FLUIDS AND COMPARATIVE CORROSION TEST DATA ON OTHER 13 CR STEELS

摘要

UNS S41427 has been in commercial production for five years. It has excellent processability and is capable of being heat treated to achieve 95ksi and 1l0ksi minimum yield variants with excellent toughness. A corrosion test programme has been carried out on the 95ksi grade to study the behaviour of UNS S41427 in a number of environments and a comparison is made with other alloyed 13-17%Cr alloys.
