Heat Resistant
Heat resistance means that the steel is resistant to scaling at temperatures higher than 500ºC (932°F). Heat resistant steels are meant for use at temperatures higher than 500ºC (932°F) since they have got good strength at this temperature and are particularly resistant to short and long term exposure to hot gases and combustion products at a temperature higher than 500ºC (932°F).
