Description
LeanDup"" 35N also known as (Uranus 35 N) is a dual phase austenitic-ferritic stainless steel that has the ability to become as important as 316L. lt offers better corrosion resistance than 316L in many environments, yet has similar machinability to 316L and a reduced cost due to the much lower nickel and molybdenum levels. This could lead to the production of highly corrosion
resistant, lower cost parts than can be attained by 316L.
LeanDup™ AO135N is one of several Austenitic-Ferritic Stainless Steels, often known as a duplex stainless steel which combines the many advantages of the other stainless steel groups. Duplex grades are generally higher strength and have better corrosion resistance. These alloys generally contain a 50-50 mix of austenite and ferrite, however, this can vary with different grades. The higher chromium content has a reduced scaling resistance than austenitic stainless steels. Plus, the duplex alloys possess increased stress corrosion cracking resistance as well as increased chlorine corrosion and intergranular corrosion resistance. Reduced weld sensitization is another advantage to these grades. These alloys are also interesting in that they contain lower amounts of nickel and can be attractive alternatives to the high nickel stainless alloys.
LeanDup™ 35N is considered a lean duplex alloy with high chromium, low nickel, and very little molybdenum contents. LeanDup™ 35N is a high strength duplex grade at almost double that of an austenitic stainless and possesses good physical properties that can offer design advantages, ease of fabrication, and good weldability. Unifonn corrosion resistance is very good along with resistance to pitting, crevice, and stress corrosion cracking.
LeanDupi™ 35N is more difficult to machine than austenitic stainless steels due to its high hardness but is very close to the machinability of Uguma 316L. Lean Dup™ 35N delivers heat to heat consistency that is unsupassed in the industry. Once an optimum set-up has been estabilisted, machinists can take advantage of the consistent quality.
