V.\u00a0<\/span><\/strong>Caracter\u00edsticas y \u00e1mbito de aplicaci\u00f3n de 30CrMnSiNi2A<\/span><\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 El 30CrMnSiNi2A tiene una alta templabilidad y buenas propiedades de mecanizado y soldadura, pero es m\u00e1s sensible a la entalla y a la fragilizaci\u00f3n por hidr\u00f3geno (incluida la fragilizaci\u00f3n por hidr\u00f3geno ambiental).<\/span><\/p>\n

\u00a0 \u00a0 \u00a0 30CrMnSiNi2A es adecuado como importante componente estructural portante de tensiones, como conectores de alta resistencia y piezas de ejes.<\/span><\/p>\n
