Various types of stainless steel are used across the whole temperature range from ambient to 1100 deg C.
The choice of grade depends on several factors:
1) Maximum temperature of operation
2) Time at temperature, cyclic nature of process
3) Type of atmosphere, oxidising , reducing, sulphidising, carburising.
4) Strength requirement
In the European standards, a distinction is made between stainless steels and heat-resisting steels.
However, this distinction is often blurred and it is useful to consider them as one range of steels.
