Abstract
PURPOSE: To enhance the hydrogen-induced crack resistance of a steel plate having a specified compsn. contg. C, Si, P and Al as basic components by controlling the combination of the S, O and Ca contents of the plate to a proper range.
CONSTITUTION: The S, O and Ca contents of a steel plate contg. C 0.005W0.20%, Si 0.01W0.80%, Mn 0.6W2.2%, P≤0.025% and Al 0.01W0.10% as basic components are controlled to S≤0.005%, O≤0.005% and Ca≤0.0120% while satifying equations I, II, III. This steel may further contain one or more out of Cu≤0.60%, Ni≤0.65%, Cr≤1.25%, Mo≤0.50%, Nb≤0.10%, V≤0.10%, Ti≤0.20% and B≤0.005%. By this component system a steel plate with superior hydrogen-induced crack resistance can be obtd. independently of a manufacturing process.
