100 years of stainless steel manufacturing

This year, it is one hundred years since stainless steel was manufactured for the first time at Sandvik and in Sweden. After the first melting in April 1921, Sandvik started regular tube production, followed by wire and strip.

Stainless steel was a good complement to Sandvik's product line at the time. The steel laboratory was enlarged to prepare for the new steel grades together with other production investments. A period of expansion and investments followed.

In 1930, the steel mill's cold-rolling operations were completely rebuilt, inside and out. Even a sintering plant and new electrical arc furnaces were set up. This became the breakthrough of stainless steel.

At this point, in the early 1930s, Sandvik had 30 different grades of stainless steel in production. In 1932, Sandvik acquired an exclusive Nordic license related to cold rolling of steel tubes using the pilgering method for 60,000 dollars. This process, further developed by Sandvik's metallurgists, made it possible to reduce both the outer diameter and the thickness of the tube material in a single rolling operation. This meant a significant rationalization because a single operation could replace several cold drawings in the earlier method, and the resulting quality was even better.

In 2022, Sandvik Materials Technology was separated from Sandvik Group and listed as an independent company on Nasdaq Stockholm under the name Alleima. Alleima is most known for its advanced duplex stainless steels. Read more at Alleima.
