Abstract

En un proceso para fabricar un tubo de acero para bolsas de aire que tiene alta resistencia y alta tenacidad que puede simplificar el moldeo en frío y reducir el costo de aleación, se formó un tubo de acero sin costuras de un acero que consta de, en porcentaje de masa, C: 0.04 - 0.20%, Si: 0.10 - 0.50%, Mn: 0.10 - 1.00%, P: cuando mucho 0.025%, S: cuando mucho 0.005%, Al: cuando mucho 0.10%, Cr: 0.01 - 0.50%, Cu: 0.01 - 0.50%, Ni: 0.01 - 0.50%, y un remanente de Fe e impurezas inevitables, y el tubo de acero sin costura se somete a moldeo en frío una vez con una velocidad de trabajo tal que la reducción de área es mayor al 40% para obtener las dimensiones predeterminadas, y después a endurecimiento con temple general instantáneo al calentar a una temperatura de al menos el punto Ac? a una velocidad de aumento de temperatura de al menos 50°C por segundo seguido de enfriamiento a una velocidad de enfriamiento de al menos 50°C por segundo a al menos un rango de temperatura de 850-500°C y al someterlo a revenido después a una temperatura de cuando mucho el punto Ac1.In a process to manufacture a steel tube for airbags that has high strength and high toughness that can simplify cold molding and reduce the cost of alloy, a seamless steel tube was formed from a steel consisting of, in mass percentage, C: 0.04 - 0.20%, Si: 0.10 - 0.50%, Mn: 0.10 - 1.00%, P: at most 0.025%, S: at most 0.005%, Al: at most 0.10%, Cr: 0.01 - 0.50%, Cu: 0.01-0.50%, Ni: 0.01-0.50%, and a remnant of Fe and unavoidable impurities, and the seamless steel tube is subjected to cold molding once with a working speed such that the reduction of area is greater than 40% to obtain the predetermined dimensions, and then to hardening with instantaneous general tempering when heating at a temperature of at least the point Ac? at a temperature rise of at least 50 ° C per second followed by cooling at a cooling rate of at least 50 ° C per second at least a temperature range of 850-500 ° C and then subjected to tempering after at a temperature of at most point Ac1.
