Restoration of a fire-damaged stainless steel food processing line

Pickling and passivation with Antox pickling agents

19.3.2021 Ing. Richard Kalný

Pickling and passivation is basically carried out by three different methods, differing in the way the pickling agent is applied. What are they and what should you pay particular attention to when applying the agents? The answer can be found in today's article.

Fire has the ability to cause unimaginable damage to property. However, not everything that survives this destructive force needs to be immediately discarded.

Immunity of steels

2.8.2023 Ing. Richard Kalný

Víte, jakým způsobem fungují antikorozní vlastnosti u austenitických ocelí? Velmi podobně, jako lidská imunita. Míra naší obranyschopnosti proti vnějším vlivům (viry, bakterie) je dána schopností těla tyto hrozby odrážet za pomocí protilátek nebo buněčné imunity.

Carbon steel, non-alloy steel, black steel...

17.8.2023 Ing. Vít Havlen

All these terms describe a material that contains a very small percentage of alloying elements and therefore cannot be considered stainless.During production and storage, products made from structural steels (excluding corrosion-resistant ones) develop layers of iron oxide on the surface.

Why is the neutralization station important?

22.1.2024 Bc. Petr Kovář

In the field of surface treatments of stainless steel, it is crucial for us not only to achieve high quality but also to minimize the negative impact on the environment. In this regard, we utilize our own neutralization station, which is used to neutralize rinse water after pickling and passivation of stainless steel.
