In most cases, it is accepted that lowering the alloy cost will also lower the performance of the material. This does not always have to be true.

The evaluation of heat-resistant alloys often relies on the chemistry and strength levels of the material. Often overlooked is the impact of microstructure on performance. The microstructure of the alloy can greatly impact the service life of bar baskets and other heat-treat fixtures.

Heat-resistant stainless steels and nickel-based alloys are commonly used for different furnace internals and carrying fixtures in the heat-treating industry. These components require periodic replacement due to a variety of factors. By understanding some of the more common causes for failure, it is possible to extend the life of these components through improved design, material selection, etc. With the alloy costs increasing significantly over the past three years, increasing the useful life of your components can help keep your maintenance costs in check.
