Severstal: Steel Defect Detection challenge

Severstal: Steel Defect Detection challenge

Steel is one of the most important building materials of modern times. Steel buildings are resistant to natural and man-made wear which has made the material ubiquitous around the world. To help make production of steel more efficient, this competition will help identify defects.

Severstal is leading the charge in efficient steel mining and production. They believe the future of metallurgy requires development across the economic, ecological, and social aspects of the industry—and they take corporate responsibility seriously. The company recently created the country’s largest industrial data lake, with petabytes of data that were previously discarded. Severstal is now looking to machine learning to improve automation, increase efficiency, and maintain high quality in their production.

The production process of flat sheet steel is especially delicate. From heating and rolling, to drying and cutting, several machines touch flat steel by the time it’s ready to ship. Today, Severstal uses images from high frequency cameras to power a defect detection algorithm.

In this competition, you’ll help engineers improve the algorithm by localizing and classifying surface defects on a steel sheet.

If successful, you’ll help keep manufacturing standards for steel high and enable Severstal to continue their innovation, leading to a stronger, more efficient world all around us.


  • 1st Place: $40,000
  • 2nd Place: $25,000
  • 3rd Place: $15,000
  • 4th Place: $10,000
  • 5th Place: $10,000
  • Efficiency Prize: $20,000
  • Efficiency Prize: Severstal will choose a winner of the “Efficiency Prize.” Participants who finish in the top 50 on the Kaggle Private Leaderboard will be allowed to submit their inference code via docker containers to Severstal for consideration for the Efficiency Prize. For each Participant that submits a solution for consideration for the Efficiency Prize, Severstal will evaluate the speed of such solution and provide a corresponding score to each Participant. Severstal will provide instructions on how to submit solutions via docker containers for consideration for the Efficiency Prize. Severstal will post the all of the results of the evaluations for the Efficiency Prize in the forum for the Competition. Participants are allowed to submit a different code than the one that places them in the Top 50, as long as that solution also scores within the Top 50.

Deadline:- 17-10-2019
