"We are constantly pushing the limits"

Published: 1 November 2018

Mårten Fexby works as technology manager at Outokumpu Stainless in Avesta. He is passionate about his work and in this article he describes what makes it so interesting. He also comments on the great need for processing engineers in the Swedish steel industry.


What tasks do you have?

- I lead and develop the processes at the hot strip plant to optimize material and product properties, minimize environmental impact, maximize productivity, safety and well-being.

In what way does your work contribute in creating a good quality of the final product?

- My group and I are constantly pushing the boundaries. Through process development we create an understanding between cause and effect. We also implement process changes which create finer surfaces, better edges, more favourable stress states, less energy consumption which gives the opportunity to manufacture more difficult products.

What is the best thing about your job?

- That I and my employees, from a white paper, together can sketch and solve difficult problems. I love to understand and discover cause and effect. I am very interested and fascinated by the shaping of steel and the connection to the material properties. We are very interested in solving difficult problems. I like the mixture of "high tech" and "low tech", for example when materials or technologically advanced things are combined with operators' experience.

What do you think about the future need for engineers in metalworking?

- There is currently no training for metal workers. The Swedish steel industry must have employees skilled in metalworking to remain in the front line.

Do you have any tips for an engineering student who is interested in working in metalworking?

- If you are fascinated by the fact that metals can be formed, for example in hot forging or in a cold forming operation and find it interesting to be able to control the properties of the material. It can be, for example, grain size, precipitates, dislocation density and phase compositions, and if you want to work with this, I think you should choose the metalworking course.

- Those who are interested are welcome to contact me and I will tell you more. I became interested in metalworking when I worked at Scania in a summer internship and had the opportunity to turn metals while they were glowing.
