Chemical composition of heat-resistant steels
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.

(*) 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.
Characteristic of heat-resistant stainless steels
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
