Slag – a tool for steel production

Slag is the tool of steel production. The lighter slag floats on the melt and can absorb and bind unwanted elements from the steel. By that, you can increase the so-called degree of purity of the steel. After the work being done the slag has different colorings (depending on the elements absorbed) and is nothing more than artificially produced rock.

The wondrous world of chemistry

Depending on its chemical composition, steel changes its properties very strongly. If it contains more than 12% chromium, it is coated with a chromium oxide layer only a few atoms thick, which protects it from corrosion. An example of such stainless steel is cutlery. By immersing stainless steel in saline solutions, the salt eats wholes into the protective layer. This can happen, for example, when too much salt is used in the dishwasher.

Merger of the Breitenfeld family

In the fiscal year 2017/18, Breitenfeld Edelstahl AG benefited from a very good market situation. Structural changes reduced business processes in order to respond more quickly and efficiently to market changes. In April 2018, Breitenfeld AG, Schmiedetechnik Breitenfeld GmbH and Sonderstahlwerk Breitenfeld GmbH were merged retroactively with June 30, 2017 to Breitenfeld Edelstahl AG. The merger took place because of several reasons. The whole product range now appears under the brand “Breitenfeld Edelstahl” and with that, the whole Breitenfeld Edelstahl family grows further together. Breitenfeld Edelstahl AG can look back on an extremely positive business development in the fiscal year […]

Electric arc furnace, steel and recycling

As of today, the most efficient way to recycle steel is the electric arc furnace (EAF). The steel is produced by passing high currents through huge graphite electrodes into the scrap. Between two of our graphite electrodes flows about as much current as through 200,000 light bulbs.
