ON THE MECHANICAL PROPERTIES AT ELEVATED TEMPERATURE AND PROPERTIES FOR OXIDATION IN SOME HEAT RESISTING STEELS OF FERRITE SYSTEM

Abstract

Heat-resisting steels of ferrite system have good machinabilities and are very inexpensive materials compared with austenite system heat resisting steels. In recent years, therefore it has been studied rapidly. The authors conducted laborious investigation on its quenching and tempering hardness, mechanical properties at elevated temperature, rupture strength, creep limit and resistance to oxidation of several heat-resisting steels of ferrite system. The informations on these characteristics, the authors believe, will surely be valuable as reference for all the users of these steels.
