Viewing the microstructure respectively the chemical analysis the heat-resistant steels can be divided in the group of ferritic and the austenitic steels and nickel-based alloys.
The melting of these alloys differs only marginally compared to the conventional ferritic and austenitic steels and nickel-based alloys.
However, some elements play a significant role when melting heat-resistant stainless steels. For example, a higher carbon (C) content as for the standard grades is applicable. Depending of the particular grades aluminum (AI), silicon (Si), nitrogen (N) but also metals of the rare earth elements like cerium (Ce) belong to these elements. In nickel-based alloys also copper (Cu), cobalt (Co) and boron (B) can be find within the composition.
In the following overview, you find some examples:

(*) Maximal suggested operation temperature to air
The requirements for these steels are not only heat-resistance but also high strength and corrosion resistance at different operation temperatures.
Very important is the criteria for fatigue strength/creep resistance at high temperatures.
Likewise, for other sectors, also here the so-called life cycle costs (LCC) play an essential role when choosing the material.
Different to the conventional ferritic, austenitic and nickel-based alloys with these particular steels the focus is doubtless on stresses due to high temperatures, as previously mentioned. The most important criteria are:
High fatigue strength/creep resistance in the wished temperature range
High temperature corrosion resistance
Scaling resistance by creation of an oxide layer
Special characteristic against stress caused by continuously changing temperatures and the resulting risk for embrittlement (depending of the used material)
Stable microstructure
High mechanical load
Heat-resistant stainless steels have a wide range of applications. Following some industries:
Ceramic industry
Glass industry
Chemical and petrochemical industry
Hardening plant
Food industry
Incineration plant
Steam boiler
Pulp industry
Various applications in the apparatus engineering
Cement industry (for example for revolving cylindrical furnace)
Industrial furnace construction (hood-type furnace for the heat treatment of coils and wires, glow systems for steel, stainless steel and nonferrous heavy metals), pusher furnace and so on
Heat exchanger for different applications in higher temperature ranges
Exhaust systems, for example in the automotive industry for exhaust elbows
