Abstract

The alloy has good weldability, good mechanical properties, and high resistance to oxidn, and creep at high temp. it contains by wt. 0.05-0.6% C, 20-55, esp. 30-55% Ni, 15-40, esp. 20-40% Cr, 0.5-2% Si, 0.5-2% Mn, 0.03-0.2% N2, 0-2, esp. 1-2% Nb, 0-5, esp. 1-3% W and/or Mo, 2-8% Al, 0-5% Cu, remainder Fe. Pref. alloys are (1) 0.1-0.5% C, 35-50% Ni, 20-35% Cr, 0.5-2% each Si and Mn, 0.05-2% N2, 1-2% Nb, 0.5-3.5% W and/or Mo, 2.5-6.5% Al, 0-3%, Cu, 0-40% Fe. (2) As alloy (1) but congt. 45% Ni, 25% Cr, 4% Al. The alloy is coated with a layer (a) preventing carburisation, and layer (a) is pref. obtd. by heating the alloy in an oxidising atmos. Esp. for mfg. components resisting carburising at over 1150 degrees C. in the petrochemical industry.
