Abstract

PURPOSE: To provide a heat resistant cast steel which causes cracking due to thermal fatigue only difficultly and suitable for use as a pot or tray material for a heat treatment furnace by adding a specified amount of Mn, Nb, etc. to 25Cr-12Ni type heat resistant steel and lowering the N content of the steel.
CONSTITUTION: This Cr-Ni type heat resistant steel contains 0.3W0.5% C, 0.5W 1.5% Si, 0.5W1.5% Mn, 22W28% Cr, 12W16% Ni and 1.0W2.0% Nb, and the N content is regulated to ≤0.05% N. This steel has superior durability to thermal fatigue due to repeated heating and cooling, and it is suitable for use as a pot or tray material for a heat treatment furnace.
