Abstract

PURPOSE: A new, low-alloy high-tensile steel contains a specific amount of C, Si, Mn, S, sol Al and Y, has an excellent toughness and ductility, and is usefull for construction steel plate, line pipes, etc.
CONSTITUTION: Steel consisting of C:0.01 to 0.15%, Si:0.01 to 0.60%, Mn:0.30 to 2.00%, S:0.008% or less, sol Al:0.004 to 0.08%, y:0.005 to 0.025%, the blance: Fe and unavoidable impurities is used to form a low-alloy high-tensile steel.
