Abstract

PURPOSE: To obtain the titled steel pipe having superior corrosion resistance in as welded state, by composing inside and outside materials of high and low alloy steels having specified compsn.s respectively.
CONSTITUTION: Inside material of welded clad steel pipe is composed of high alloy steel contg. by weight, ≤0.07% C, ≤1% Si, ≤2% Mn, ≤0.03% P, ≤0.01% S, ≤0.3% sol. Al, 27W40% Ni, 18W25% Cr, 0.01W2% Cu, one or 2 kinds among ≤5% Mo and ≤10% W, one or 2 kinds among ≤1% Ti and ≤1% Nb and the balance Fe with inevitable impurities, under Cr % + 10 Mo % + 5 W % ≥ 40%, 2 % ≤ Mo % + 1/2 W % ≥ 5%, Ti % / C % + Nb % / C % ≥5. On the other hand, outside material is composed of low alloy steel contg. 0.05W0.2% C, 0.01W0.5% Si, 0,.8W2% Mn, ≤0.015% P, ≤0.002% S, ≤0.1% sol. Al, 0.0005W0.02% Ca and the balance Fe with inevitable impurities.
