ABSTRACT:
Chromium-molybdenum structural steels which have high tensile strength, low susceptability to temper embrittlement, high hydrogen attack resistivity and high temperature ductility and which can be formed into very thick steel plates comprise 0.05 to 0.20% of C, 0 to 0.15% of Si, 0.46 to 1.00% of Mn, 2.00 to 3.50% of Cr, 0.80 to 1.20% of Mo, 0.00015 to 0.0015% of B, 0.005 to 0.070% of Sol. Al and inevitably entrained impurities, the balance to make up 100% of Fe. Preferably the inevitably entrained impurities of nitrogen and phosphorus are below 0.0060% of N and 0.0010% of P.
