Il tipo di acciaio temprato precipitato con aggiunta di rame viene sviluppato sostituendo 2% di cromo nell'acciaio 0Cr17Ni7Al con 2%-3% di molibdeno. Le prestazioni di base sono simili a quelle dell'acciaio 0Cr17Ni7Al, ma le prestazioni complessive sono migliori di quelle dell'acciaio 0Cr17Ni7Al. Allo stato di austenite, pu\u00f2 sopportare vari processi di formatura a freddo e di saldatura, e poi il trattamento termico pu\u00f2 ottenere la massima
