Que es el acero inoxidable V2A y V4A?

Para empezar podemos confirmar que el acero inoxidable usad es austenítico.

Con referencia a los grados de SAE, significa que pertenece a la serie 300.

Contienen un maximo de 0.15% de carbon, un minimo de 16% de cromo y suficiente nickel y/o magnesio para retener una structura austentica.

V4A es el estandard aleman, este material se usa en condiciones mas acerbas como en los tuneles para fijar las luces.

Por que? La alta humedad de los tuneles combinada con los gases emitidos por los coches produce una atmosfera bastante acida.
