Choosing the Proper Heat Resistant Alloy Based on Application Criteria

In today’s competitive world of globalization and low cost manufacturing, it is essential that when engineering a job, to get it right the first time. This is especially true for capital equipment with a high cost and long expected lifetimes. It is even more critical, when the equipment must operate at high temperatures, and different potential for failure exists. In order to do it right the first time, engineers must understand high temperature properties, and incorporate these principles into the decision making process for materials. Some of these properties are intrinsic, some are affected by environment, and some are governed by thermodynamic and kinetic changes to the material at the operating temperatures. All must be considered.
