Abstract
Alloy for temps. up to 1000 degrees C and corrosion-resistant at these temps. contains 0.3-0.7 (pref. 0.4-0.6)% C, 24-3 (25-28)% Cr, 30-40(33-38)% Ni, 10-27 (13-20)% Co, (Ni+Co) >=45%, and up to 1% Zr, plus usual impurities and >=12.5% Fe. Pref. also contains 0.7-2% Nb and 4-6% W. Used esp. for tubes of hydrocarbon reforming tubular reactors.
