Abstract
PURPOSE: To produce a clad steel pipe excellent in abrasion resistance and weldability, by forming a clad steel sheet having a hard steel as a core and a soft steel as an outer layer into a steel pipe for transporting slurry.
CONSTITUTION: The core 3 of a hard steel containing C<0.50%, Si=0.05W1.00%, P≤0.04%, S≤0.02%, Al<0.01% and at least one or more selected from Cn= 0.20W2.00%, V≤0.20%, Mo=0.05W1.00% and B=0.0005W0.0035% is placed in a mold 1, and then is surrounded with a molten metal 2 of a soft steel containing C<0.50%, Si=0.05W1.00%, P≤0.04%, S≤0.02% and Al<0.10%, and subsequently the molten metal is solidified. Alternatively, the cores 3 are layered with a parting plate 7 therebetween, and after the solidification, by removing the parting plate 7, a clad steel having two or three layers composed of the soft steel 2' and the hard steel 3' is obtained. From this, a clad steel pipe that consists of the outer layer (or outer and inner layers) 2' excellent in the weldability and the core 3' excellent in the abrasion resistance can be produced.
