Calzot® - an efficient and accurate way of Nitridation in secondary metallurgy
European steel producers face the need to cover the high quality market with their products. Consumer of steel take following considerations into account: component properties like corosion resistance or fatigue resistance, but also economic issues (e.g. expensive cost driving metals) and machinability. Nitrided steel grades are gaining attention since a reduction of cost driving alloying elements is of increasing importance in the steel industry. In addition, the energy consumption is reduced, as these steel grades enable a less intense heat treatment.
Adding Calzot® to the liquid steel before casting leads to a very precise alloying technique. We provide our customers with granulated Calzot® as well as Calzot® Cored Wire.
The advantages of Calzot®:
- Calzot® possesses a high and stable nitrogen content (23,5 w %) and a high N-Yield (up to 75 %).
- Calzot® enables a precise alloying result and hence no post-corrective alloying
- Low input of impurities and tracer elements compared to Nitrogen containing ferro-alloys
- Less temperature and energy losses in comparison to nitrogen gas purging
- Lower costs in comparison to the application of nitrided ferro-allyos
Alzchem stands for solutions, high quality and flexibility so that we generate satisfied customers.

About Alzchem
Alzchem is a globally active specialty chemicals company that is predominantly among the market leaders in its fields of activity. Alzchem benefits in particular from the three very different global developments of climate change, population growth and longer life expectancy. In order to achieve the resulting social goals, Alzchem products can offer attractive solutions with a wide range of different applications.
The company sees interesting growth prospects for itself especially in the areas of human and animal nutrition and agriculture. As a result of population growth, it is necessary to achieve efficient food production. Pharmaceutical raw materials and our creatine products can contribute to healthy aging as life expectancy increases. Alzchem is facing up to the goal of sustainability arising from climate change in the field of renewable energies and across the entire company. The fields of fine chemicals and metallurgy offer just as great a perspective.
The broad product range of Alzchem Group AG includes dietary supplements, precursors for corona tests and pharmaceutical raw materials. These products are our company’s response to global trends and developments. Alzchem is ideally positioned in this regard and sees itself as well equipped for an environmentally oriented future and global developments.
The company employs around 1,630 people at four production sites in Germany and one plant in Sweden, as well as two sales companies in the USA and China. In 2020, Alzchem generated consolidated sales of around EUR 379 million and EBITDA of around EUR 53.8 million.
