API TR 942-B First Edition PDF
This technical report focuses on the materials, fabrication, and repair of austenitic stainless steels and nickel-iron-chromium alloys in high temperature 565-760 °C (1050-1400 °F) refinery services. Many of these alloys are subject to embrittlement and cracking after prolonged exposure to these temperatures.
Susceptible equipment in the following processing units are addressed: fluid catalytic cracking units, hydrogen/syngas plants, catalytic reformers, cokers, and hydroprocessing units.
This report summarizes industry experience and recommends methods to improve reliability and process safety, and increases industry awareness to high-temperature embrittlement issues.
