Abstract

Composiciones de acero que contienen adiciones de microaleacion de boro y titanio, con una resistencia a la traccion de por lo menos 100 ksi (690 MPa), excelente rigidez y buena capacidad de soldadura. Las adiciones de boro son utilizadas para incrementar el endurecimiento. Es posible agregar formadores de nitruros fuertes, como titanio, a la composicion de acero en orden a impedir la formacion de nitruros de boro. Estas composiciones pueden ser enfriadas por laminado en caliente en aire o por aplicacion de un enfriamiento acelerado. Luego del enfriamiento en aire, la composicion puede ser apagada o apagada y templada. Las composiciones resultan adecuadas para canos de alta resistencia (por ejemplo, X100 en la norma API 5L) y otras aplicaciones. Reivindicacion 9: Un método de fabricacion de una composicion de acero, que comprende: proveer una composicion de acero que comprende: aproximadamente entre 0,04 y 0,12 % en peso de carbono (C); aproximadamente entre 0,8 y 1,6 % en peso de manganeso (Mn); aproximadamente entre 0,05 y 0,3 % en peso de silicio (Si); menos o hasta aproximadamente 0,5 % en peso de níquel (Ni); menos o hasta aproximadamente 0,5 % en peso de cromo (Cr); menos o hasta aproximadamente 0,5 % en peso de molibdeno (Mo); menos o hasta aproximadamente entre 0,15 % en peso de vanadio (V); menos o hasta aproximadamente entre 0,05 % en peso de niobio (Nb); aproximadamente entre 0,01 y 0,03 % en peso de titanio (Ti); aproximadamente entre 0,0005 y 0,0030 % en peso de boro (B); y menos o hasta 0,008 % en peso de nitrogeno (N); en tanto la concentracion de cada elemento se basa en el peso total de la composicion de acero y se mantienen aproximadamente entre 0,0005 y 0,002 % en peso de boro en solucion solida para mejorar la dureza; colar la composicion de acero, en tanto sustancialmente todo el nitrogeno en la composicion de acero colada está presente en forma de partículas de TiN con un tamano inferior a aproximadamente 50 nm para impedir la formacion de nitruros de boro y lograr dicho contenido de boro en solucion solida; laminar en caliente la composicion de acero colada; y enfriar la composicion de acero colada directamente luego del laminado en caliente a una velocidad que oscila aproximadamente entre 5 y 50°C/segundo.Steel compositions containing additions of boron and titanium microalloy, with a tensile strength of at least 100 ksi (690 MPa), excellent rigidity and good weldability. Boron additions are used to increase hardening. It is possible to add strong nitride formators, such as titanium, to the steel composition in order to prevent the formation of boron nitrides. These compositions can be cooled by hot rolling in air or by application of accelerated cooling. After cooling in air, the composition can be turned off or turned off and tempered. The compositions are suitable for high strength gray hair (for example, X100 in API 5L) and other applications. Claim 9: A method of manufacturing a steel composition, comprising: providing a steel composition comprising: approximately 0.04 to 0.12% by weight of carbon (C); approximately between 0.8 and 1.6% by weight of manganese (Mn); approximately between 0.05 and 0.3% by weight of silicon (Si); less or up to about 0.5% by weight nickel (Ni); less or up to about 0.5% by weight of chromium (Cr); less or up to about 0.5% by weight molybdenum (Mo); less or up to about 0.15% by weight vanadium (V); less or up to about 0.05% by weight of niobium (Nb); approximately between 0.01 and 0.03% by weight of titanium (Ti); approximately between 0.0005 and 0.0030% by weight of boron (B); and less or up to 0.008% by weight of nitrogen (N); while the concentration of each element is based on the total weight of the steel composition and approximately 0.0005 and 0.002% by weight of boron in solid solution are maintained to improve the hardness; casting the steel composition, while substantially all of the nitrogen in the cast steel composition is present in the form of TiN particles with a size less than about 50 nm to prevent the formation of boron nitrides and achieve said boron content in solution solid; hot rolling the cast steel composition; and cooling the cast steel composition directly after hot rolling at a speed ranging from about 5 to 50 ° C / second.
