Abstract
PURPOSE: To provide a Cr-Mo steel for press, vessel improved in toughness after use in embrittle temp. range without causing decrease in high-temp. strength, by decreasing S content of the Cr-Mo steel of a specific composition, and by addn. particularly limitted amount of Ca.
CONSTITUTION: A Cr-Mo steel comprising by weight, 0.08W0.20% C, ≤0.50% Si, 0.20W0.90% Mn, 1.00W3.50% Cr, 0.40W1.50% Mo, 0.005W0.150% Ca, the balance being <0.010% S and Fe including inevitable impurities, the steel is improved in toughness before embrittle treatment by decreasing S, decreased in embrittlement susceptibility by the addn. of a limited amount of Ca, and has excellent toughness after use in embrittle temp. range for a long time.
