  1. 1. Together we can push the limits of metal powders The Höganäs metal powders for Additive Manufacturing
  2. 2. Höganäs short facts ● Largest iron powder producer in the world ● 2800 customers in 75 countries ● More than 1,500 products, mostly customer specific, from 13 production centers ● Around 700 granted patents ● Global volume +/- 400 000 tons ● Turnover 2014: +/- 650 MEUR ● Established in 1797 as a coal mining company ● Owned by FAM and Lindéngruppen 2 | Europe 31% Americas 32% Asia 37% Markets (2013) Introducing Höganäs
  3. 3. Gas Atomisation is used to produce powders Additive Manufacturing powders Olof ANDERSSON | Höganäs Belgium SA3 |
  4. 4. Höganäs focus. Additive Manufacturing Powders Stainless steel : 316 / 410 / 420 ………… Tool steels : H13 / M2 …. Nickel alloys: 625 / 718 / Hast 276…….. Cobalt base : CoCr , CoCrWC ………. Olof ANDERSSON | Höganäs Belgium SA4 |
  5. 5. SIRRIS / background. ● Since a couple of years Höganäs see more and more demands for powder to be used in Additive Manufacturing. ● Markets not fully defined ● Technical requirements from customers are unclear. Particle size ? Trace elements? ● Are our powders performing correctly in the common processes? ● Need to verify but how? Olof ANDERSSON | Höganäs Belgium SA5 |
  6. 6. SIRRIS Reality check with SIRRIS. Will our powder perform in the common processes? ● SLM and DED ● 316L and IN 625 - > 4 different powders. ● Powder behaviours in the printers? Flow, particle size and shape. ● Mechanical properties in build components? Olof ANDERSSON | Höganäs Belgium SA6 |
  7. 7. Confirmed flowability trials with 20-53 µm on a commercial SLM equipment. ● Flowability main tank to recoater - OK ● Flowability recoater to chamber - OK ● Spreading aspect on base plate - OK Olof ANDERSSON | Höganäs Belgium SA7 | 20-53 µm is working successfully down to layer thickness of 30 µm
  8. 8. Feasibility of production. Core and contour settings optimization jobs. Olof ANDERSSON | Höganäs Belgium SA8 | - Support settings - Core settings - Contour settings Several optimization jobs are carried out, producing a matrix of cubes of each material. They will be afterwards visually inspected and a density analysis will be performed.
  9. 9. The initial window of variables measured for the core. Olof ANDERSSON | Höganäs Belgium SA9 |
  10. 10. Conclusion of SLM evaluation. ● The powder flowability was revealed good. ● Höganäs powder 20-53um SS 316L allowed to produce dense parts. ● The tensile samples show values expected values for the SLM technology. Olof ANDERSSON | Höganäs Belgium SA10 |
  11. 11. DED, Directed energy deposition Olof ANDERSSON | Höganäs Belgium SA11 |
  12. 12. Olof ANDERSSON | Höganäs Belgium SA12 | Front (left) and back (right) faces of 316L sample. Laser Power 930 W, Speed 300 mm/min, powder flow 3,8 g/min, average layer thickness 375 μm.
  13. 13. Conclusion from DED ● The Powders tested was suitable to have a well-shaped powder flow out of the nozzle. ● High dense parts ( > 99.3 % pores) were obtained. ● Tensile results shows mechanical values in the same range than expected in the literature for YTS, UTS for DED samples. Olof ANDERSSON | Höganäs Belgium SA13 |
  14. 14. Final Conclusion ● Based on SIRRIS report we felt secure to go to the market with our powders. ● Market plan ● Launched marketing and sales support activities. ● The report is beneficial tool to enter materials lab and R/D centres. ● Commercial successes in Europe and USA Olof ANDERSSON | Höganäs Belgium SA14 | Exhaust part for a racing car Höganäs IN 625
  15. 15. Olof ANDERSSON | Höganäs Belgium SA15 | Thank you for your attention!
