Melting temperature ranges for stainless steels:

Stainless steels are alloys and therefore do not melt and freeze at a fixed temperature, as do metallic elements, but over a temperature range, depending on the chemical composition of the steel.
Alloy additions also suppress (lower) the melting range. Pure iron (Fe) has a fixed melting point of 1535°C, chromium (Cr) 1890°C and nickel (Ni) 1453°C compared to a range of 1400-1450 °C for type 304 stainless steel.

Maximum service temperatures in air for stainless steels:

        + Austenitic stainless steel types

As below table:

       + Ferritic, duplex and martensitic stainless steel types

The ferritic types may be limited, in practice, to lower temperatures as they have lower strengths at elevated temperatures than the austenitic types.

Duplex stainless steels can also be prone to embrittlement and so although their chromium levels would suggest they may be useful steels for elevated temperature service. This steel family is limited in the European pressure vessel standard EN 10028-7 to a maximum temperature of 250 degree C.

The martensitic types are not considered here: These steels are usually selected for their hardness and strength, which will be reduced when their tempering heat treatment temperature is exceeded, thus limiting their usefulness for elevated temperature service.
