Abstract
PURPOSE: To provide the title steel, high in tensile strength and little in porocity and segregation at the center of cast product in operation range of usual molten steel temperature not causing casting trouble by adjusting each content of C, Si and Mn in seamless pipe steel to meet three specific equations.
CONSTITUTION: Each content of C, Si and Mn in seamless pipe steel is adjusted to simultaneously satisfy the following three equations: (%C)+(%Mn)/12.5≤0.53, (%C)+(%Mn)/6≥0.55 and 0.01≤(%Si)≤0.5. This method makes it possible to provide, by continuous cast process, material completely free from center porocity and having tensile strength of 65kg/mm2 or more.
