HMn58-4 korkea mangaani messinkinauha Suomi

HMn58-4 manganese brass has high corrosion resistance in seawater, superheated steam, and chloride, but has a tendency to corrode and rupture; Good mechanical properties, low thermal and electrical conductivity, easy to perform pressure processing in hot state, and acceptable pressure processing in cold state, making it a widely used brass variety. HMn58-4 manganese brass is used as an important component for working under corrosive conditions and for low current industrial parts.
