Abstract
PURPOSE: To enhance the stopping characteristics of brittle rupture propagation for the titled steel and the toughness of the high heat input welded bond zone of the steel by restricting the carbon content of the steel to a specified range, reducing the Si content, and controlling the Mo content low.
CONSTITUTION: This high strength steel for high heat input welding is high C-low Si-low Mo steel having a composition contg. 0.16W0.25% C, <0.10% Si, 0.70W 1.20% Mn, 0.20W0.50% Cu, <2.00% Ni, 0.40W1.00% Cr, 0.05W0.25% Mo, 0.02W0.05% V, 0.001W0.003% B and 0.03W0.06% sol. Al. By the C content restricted to said range in combination with the reduced Mo content this steel has enhanced the stopping characteristics of brittle rupture propagation, and the toughness of the high heat input welded bond zone is improved. In addition, the reduced Si content results in further enhanced toughness of the bond zone.
