1.4462 duplex stainless steel is a really good grade for corrosion resistance and mechanical properties. This grade is written as 1.4462 or X2CrNiMoN22-5-3 according to EN norm and it is written as UNS S31803 or S32205 according to UNS norm. Some producers can also name this 1.4462 material as Temet, Aquashaft, Marinox but the actually, all this names are equal to 1.4462 duplex stainless steel.
1.4462 materials have a good price/performance. The duplex names comes from properties of this grade, because this grades shows two different stainless steel grade phases and this is why it is called duplex. 1.4462 material shows both ferretic and austenitic stainless steel class properties. 1.4462 material has a better corrosion resistance then 316L and 316Ti. Also the mechanical properties are %50 higher then most of the austenitic grades(like 304). In Birçelik warehouse, we keep this grade in special dimension tolerances and in special surface qualities. In Birçelik warehouse, you can find 1.4462 grade in H9 Grounded surface up to 8.5 meter lenght and these special materials are for prepoller shafts and all 1.4462 materials are ready for immediate shipment.
