inconel x750 bar

Inconel X-750, designado como UNS N07750, W.Nr. 2.4669, NiCr20TiAl, GH4145 y ХН77ТЮР, es una superaleacion base niquel-cromo-hierro con endurecimiento por precipitacion mediante fase gamma prima (Ni3(Al,Ti,Nb)). En SHUNFU METAL, cada lote se produce y verifica bajo nuestros sistemas de gestion certificados ISO 9001 y API Q1, con trazabilidad completa desde la materia prima hasta el producto final. Esta aleacion ofrece una combinacion excepcional de resistencia mecanica a alta temperatura, excelente resistencia a la oxidacion hasta aproximadamente 980 °C y notable resistencia a la relajacion de tensiones por debajo de 540 °C, lo que la convierte en la eleccion de referencia para los sectores aeroespacial, nuclear, de turbinas de gas y petroquimico.
