Abstract
PURPOSE: To obtain a steel that is excellent in the weldability and has high tension after the hardening and tempering, by increasing the quantity of Ni in an Ni-Mo steel, adding Cu, and specifying the C equivalence.
CONSTITUTION: The steel contains 0.15W0.20% of C, 0.20W0.60% of Si, 0.50W 1.50% of Mn, 0.020% or more of S, 2.0W3.0% of Ni, 0.25W0.45% of Cr, 0.25W 0.50% of Mo, 0.01W0.10% of V, 0.10W0.5% of Cu and the rest of substantially Fe, and the carbon equivalence (C eq) given by "Formula is 0.65 or below. The Ni is very improtant to secure the toughness, and is required in an amount equal to the minimum or limit more, but if it exceeds the maximum limit, it will not economical. The Cu improves the anticorrosiveness, and contributes to the strength and the toughness, and if it is added in a quantity below theminimum limit, the effect is not observed, and if it is added in a quantity above the maximum, the effect is saturated. The reason why there is the c equivalence is to secure the weldability. when the steel is hardened and tempered after the casting, it has a tensile strength of about 80kg/mm2 or more, and the welded section of the steel can retain impact resistance properties.
