Buenas tardes.

Somos Caleb Hernández y Antonio Salas.

Necesitamos saber una recomendacion por parte de ustedes acerca de cual tipo de material de aporte en GMAW utilizar, sobre unos materiales identificados como:

28CrMoNiV59   equivale a un: ASTM A-470 Grado D    con una dureza de 24 HRc
34CrMo4    equivale a un: 4135    con una dureza de 223 HB
30CrNiMo8 equivale a un:4330    con una dureza de 26HRc

Estos son unos ejes de turbinas a vapor y compresores centrífugos la cual estamos realizando un procedimiento de soldadura para reparar por medio de relleno el área de muñones.

gracias...
