Cold-drawn profiled steels have poor thermal conductivity at low temperatures, but the coefficient of linear expansion is larger than that of carbon steel. In order to ensure the quality of heating, low temperature and slow heating should be adopted. Cold drawn profiled steel has good oxidation resistance, because cold drawn profiled steel has oxidation resistance...
