Abstract
PURPOSE: To enhance the weldability of the titled steel and the erosion corrosion resistance in wet vapor by preparing a low C-Cr-Mo steel having a specified composition contg. Si and Mn.
CONSTITUTION: This low C-Cr-Mo steel has a composition consisting of, by weight, 0.02W0.14% C, 0.45W0.90% Si, 0.30W0.80% Mn, 0.70W1.60% Cr and the balance Fe with inevitable impurities. The composition may further contain ≥1 group of element selected from ≤0.5% Cu and Ni and/or ≤0.005% B, ≤0.05% Nb and/or ≤0.08% V, and 0.005W0.08% one or more among Al, Ti and Zr.
