“Which brand produces the strongest cars in the world?” We know that many of you would say “Volvo”. You are not wrong about this; Because, apart from preventing accidents, Volvo is produced under very special conditions in order to keep the people inside alive in the event of an accident.
Volvo has a lot of work to increase human safety, but the thing that strengthens the company’s hand in this regard lies in the quality of the steel they use. Volvo is a company that was founded in Sweden and continues to produce in Sweden, although it is now in the hands of a Chinese company. Sweden has some advantages over other countries in steel production.
What makes Swedish steel so different, which is stronger than other steels?
Steel is an extremely strong substance produced from iron ore. At this point, there are two important points where Swedish steel makes a difference. The Swedes are one of the societies that can process iron ore well. The biggest advantage of the Swedes, who have iron and steel production experience dating back to the 13th century, lies in the rich mixture of iron coming from their country.
The ore behind Volvo’s robustness: Swedish iron ore deposits
Swedish iron ore deposits also contain some metal ores that make steel a natural alloy. The small percentage of many ores, especially vanadium (V), imparts high tensile strength to steel. This allows a special steel production that prevents it from breaking under hard impacts and makes it harder.
The way Swedish steel is heated is also different.
A very large part of the world’s steel production is formed by the “open hearth” process of turning iron into steel by applying very high temperatures. This method makes the steel stronger but more brittle.
In Sweden, “electric arc furnace” is used. In this system, metal is heated at lower temperatures in small batches. This makes Swedish steel more flexible and softer, although not as strong as the “open hearth” method. In fact, this flexibility gives the substance more strength.
The result is more durable cars.
Of course, Swedish steel is not the only use for automobiles. We see that Swedish steel is preferred in many sectors such as construction. But when it comes to life, we see that Volvo has done well with Swedish steel.
We even see that Volvo is trying to improve itself more at this point. The company is known to add boron to this steel alloy, further increasing the structural strength.
