Abstract

PURPOSE: To provide a high Cr steel contg. a specified amount of C, Si, Mn, P, S, Ni, Cr, Mo, W, V, Nb and Al, having a specified ferrite content calculated by a specified equation, and showing high strength at high temp., superior workability, superior weldability, corrosion resistance and high toughness.
CONSTITUTION: This high Cr steel consists of 0.05W0.18% C, <1% Si, 0.2W1% Mn, <0.025% P, <0.015% S, <0.75% Ni, 10W15% Cr, 0.5W3% Mo, 1W3% W, 0.2W0.5% V, 0.05W0.3% Nb, <0.05% Al and the balance Fe with inevitable impurities. The ferrite content of this steel calculated by equation I is 10W40%, and equations II are also satisfied.
