BORINOX® in food technology

In food technology, high demands are placed on the material properties of parts and components. Robust, corrosion-resistant and easy-to-clean materials are required that do not change the taste or color of the products when they come into contact with food. Corrosion-resistant stainless steel exhibits these properties. For this reason, stainless steels such as 316 or 316L are widely used and popular materials in the food industry. They are used, among other things, for media transport and processing of food in machines, for food-safe containers (e.g. tanks and boilers) for equipment such as mixers, pumps, dosing devices, kneaders and for equipment in commercial kitchens.

Every user is familiar with stainless steel grades, for example as cookware or cutlery, from the private sector. The majority of the steel grades used have a chromium content of at least 18% and a nickel content of 10%. This alloy composition has proven itself in terms of corrosion resistance to various foods and beverages. In general, the higher the hardness of a material, the more robust the material is against mechanical stress. Stainless steel grades such as 1.4301, 1.4401, 1.4404 have a low resistance to abrasive stress. The use of the BORINOX® hardening process increases the surface hardness many times over without negatively affecting the corrosion properties and helps to manufacture products that are more durable, reliable in production and cost-optimized.
Hardening stainless steel with BORINOX® is used in many areas of the food industry. Especially, components that are exposed to high mechanical stress are refined. Hardened parts can be found in processing plants for chocolate production, in filling plants in the beverage industry, in dosing pumps for yogurt filling, in mixers and agitators, to show just a small selection of the diverse spectrum.

How does hardening stainless steel help?

Treating stainless steel with BorTec’s BORINOX® hardening process can significantly extend the durability and service life of machined components that would otherwise be worn out by erosion, corrosion, ADHESION, tribooxdidation or cavitation. At the same time, the corrosion properties of the machined material are preserved and are not affected by the process. The improvement of the surface hardness makes the material more robust and resistant to any kind of external stress.

These materials can be hardened with the BORINOX® process

The BORINOX® hardening process can be used to treat all stainless steel grades used in food processing technology. It does not matter whether they are ferritic, martensitic, austenitic or duplex steels. Due to their high chromium and nickel content, austenitic grades such as 1.4301, 1.4401, 1.4404, 1.4435 are preferred.
