Even Superb materials as 254 SMO wear and tear, like today….
SMO254 is a high-alloy austenitic stainless steel developed for use in seawater and other aggressive chloride-bearing media. The steel is characterized by the following properties:
Excellent resistance to pitting and crevice corrosion, PRE = ≥42.5*
High resistance to general corrosion
High resistance to stress corrosion cracking
Higher strength than conventional austenitic stainless steels
