3 Market Introduction Lorem Ipsum Lorem Ipsum Formable Duplex - FDX The color of this box can be changed to suit the background image The worlds most formable duplex grades 3

4 General characteristics of Duplex grades Higher mechanical strength than for standard grades Good to excellent corrosion resistance Good weldability Higher fatigue resistance than for standard grades High resistance to stress corrosion cracking and corrosion fatigue High wear resistance In spite of the good inherent properties of duplex the formability could be improved 4

5 Outokumpu new Duplex concept Outokumpu has developed a new duplex concept based on utilizing Transformation Induced Plasticity (TRIP) Providing a solution to the limited formability of current duplex grades The newly developed Formable Duplexes: Outokumpu FDX 25 Outokumpu FDX 27 5

6 Outokumpu FDX value proposition FDX Formable duplex Increased formability Allows the utilization of duplex in applications where it has not been possible before General duplex benefits High strength High corrosion resistance High resistance to stress corrosion cracking Lower price volatility 6

7 Outokumpu Duplex concept The new Duplex concept exhibits a totally unique combination of high strength, high elongation and price stable alloying. The concept provides a totally new stainless steel solution for applications where the formability of current duplex grades are not sufficient Elongation, % 304L 316L 904L 254 SMO Austenitic Duplex Ferritic 50 Elongation, % 304L Austenitic Duplex Ferritic L 4565 FDX 25 FDX FDX 27 FDX L 254 SMO LDX LDX LDX Yield 650strength, MPa Corrosion resistance 7

8 Positioning of the new Duplex grades An excellent combination of high strength and corrosion resistance Strength - R p0.2 [MPa] Duplex FDX 25 LDX FDX 27 LDX LMN 2205 Min values EN 10088, cold rolled SMO Austentic 304L 316L 316hMo 317L 904L 150 Corrosion Resistance - CPT typical, ASTM G150 8

9 Tensile tests: FDX 25, LDX 2101 and 304L True stress [MPa] FDX 25 LDX L ,1 0,2 0,3 0,4 0,5 True strain [-] 9

10 Stretchability test Stretching test that generate a strain state close to plane strain conditions 304L 316L Stretchability test FDX 25 FDX 27 LDX

11 Corrosion test CPT ( o C) < 10 Typical Critical Pitting Temperature (CPT) values according to ASTM G150 11

12 Successful forming trials The same tool geometry and design were used as for 304L Only a few process parameters were changed (i.e., press force) Very promising results! Plate heat exchanger 12

13 Potential applications Only the imagination sets the limits Some examples: Plate heat exchangers Flexible pipes Pumps components Beer kegs.. 13

14 Customer gains Improved formability compared to current duplex grades Can be utilized in applications where duplex has been restricted due to formability limitations, thereby offering: Thickness reduction potential Increased operation pressures Better fatigue properties Forming intensive structural components Less volatile prices in comparison with austenitic grades Compared with ordinary duplex grades: Improved productivity in manufacturing 14

15 Pump components Pump manufacturers Today mainly 304/316 Dimension range 0,5 4 mm FDX value proposition: Formability: Allows the use of duplex in parts it hasn t been possible before High Strength: Reduced thickness Higher fatigue strength & erosion resistance Higher pressures/pump efficiency Enables possible new products 15

16 Flexible pipes Flexible pipe manufacturers Today many of Outokumpu s alloys Dimension range 0,8 3,5 mm FDX value propositions: Formability: Higher productivity Possibilities for new designs High Strength: Reduced thickness & higher fatigue strength Deeper water challenges Improvement of the anticollapse resistance Enables possible new products: Ultra deep water applications Fatigue demanding applications 16

17 Plate heat exchangers Plate heat exchangers market Today mainly 316/304 Dimension range 0,25 2 mm FDX value propositions: Formability: Allows the use of duplex High Strength: Reduced thickness or allows higher operating pressures Better fatigue properties Enables possible new products: High pressure & fatigue demanding application 17

18 Beer kegs Beer kegs producers Today mainly 304/316 Temper rolled material is used for support rings Dimension range 1,0 3,0 mm FDX value propositions: Formability: Allows the use of duplex High Strength: Reduced thickness Substituting TR austenitic grades 18

19 Plan for market introduction Selected pilot customers Active product management Expand geographically and applications Inclusion in key standards 19

20 Plan for standardisation Immediately: EN Number UNS Number ASTM A240 Prioritized: EN EN ASME SA

21 Conclusions Adds formability Price stability Improved productivity New applications 21
