Abstract
A structural member to be subjected to a hot gas atmosphere produced through reaction between coal and a gasifier such as oxygen, air, steam or hydrogen, in a gasification furnace for example. The structural member is made of an anti-sulfur attack Cr-Ni-Al-Si alloy steel which has a composition essentially consisting of, by weight, 0.03 to 0.3% of C, 1 to 10% of Si, not greater than 2.0% of Mn, 8 to 14% of Ni, 16 to 20% of Cr, 0.5 to 10% of Al and the balance not less than 50% of Fe.
