Why Duplex 1-4462 instead of AISI 316
All VETUS propeller shaft are made of stainless steel type “Duplex 1- 4462”. In comparison with stainless steel materials like AISI 316 and Aquamet 17 or 22, the corrosion resistance of “Duplex 1-4462” is much greater. In addition the tensile strength of “Duplex 1-4462” is about 30% greater than AISI 316 and its hardness is approximately 40% higher. It is precisely this high degree of hardness, which gives “Duplex 1-4462” its excellent running properties in rubber bearings.
