Summary of the lecture
This course is based on the American Iron and Steel Institute publication High-Temperature Characteristics of Stainless Steel (Designers’ Handbook Series No. 9004), originally produced by the Committee of Stainless Steel Producers and republished by the Nickel Institute.
It offers essential guidance for engineers, designers, and materials specialists concerned with the selection and use of stainless steels in high-temperature environments. Drawing from decades of industrial experience and research, the course compiles engineering data and design principles relevant to strength, stability, and corrosion resistance at elevated temperatures.
The publication examines the key factors governing material performance under thermal stress—including creep, creep-rupture, oxidation, and embrittlement—while also addressing cost, service life, and environmental considerations.
What you will learn:
- Understand the fundamental factors influencing stainless steel performance at elevated temperatures, including service life, allowable deformation, environmental effects, and cost considerations in material selection.
- Explain the key mechanical behaviors of stainless steels under high-temperature service, such as short-time tensile strength, creep, and creep-rupture, and how these properties affect design stresses and safe operating limits.
- Differentiate between stainless steel types and grades used in high-temperature applications, including the significance of “H” and “N” designations, carbon and nitrogen control, and the relative performance of austenitic, ferritic, and martensitic families.
- Evaluate the effects of prolonged heat exposure on metallurgical stability, including softening, carbide precipitation, embrittlement (such as 885°F embrittlement), and grain-size effects on strength and ductility.
- Assess the corrosion and oxidation resistance of stainless steels at elevated temperatures, recognizing the roles of chromium, nickel, and silicon in improving scaling resistance and surface stability in air, steam, and process gases.
- Identify material behavior in specific high-temperature environments, such as sulfidation, carburization, hydrogen attack, ammonia exposure, and reactions with halogens or liquid metals, and select appropriate alloys for these conditions.
- Apply ASME and ASTM high-temperature design standards to determine allowable stresses, evaluate creep-rupture data, and ensure compliance with codes for pressure vessels and other high-temperature equipment.
