Abstract
A heat-resistant alloy having a high creep rupture strength under high-temperature low-stress conditions and excellent resistance to carburization even when used at a high temperature exceeding 1100.degree. C. The alloy comprises, in % by weight, more than 0.1% to less than 1.5% of C, more than 2% to less than 3% of Si, more than 0% to less than 2% of Mn, more than 20% to less than 30% of Cr, more than 25% to less than 40% of Ni, more than 0.6% to less than 2% of Al, and the balance Fe and inevitable impurities. When required, the alloy contains at least one component selected from the group consisting of 0.01 to 0.5% of Zr, up to 0.2% of N, 0.2 to 2.0% of Nb, 0.2 to 2.0% of W and 0.01 to 03% of Ti.
