Special materials

Dedicated fastening materials are used for high-quality constructions and environments.

Think in terms of acid-resistant material (such as steel with material no. 1.4529) for use in swimming pools, heat-resistant fastening materials for use in furnaces, and Duplex or Super Duplex steel for surroundings that involve the use of corrosive substances (e.g. material no. 1.4462). Each article has its own specific use and area of application.
This group of special fastening articles includes the following material categories.

Low-temperature resistant steel
Stainless and acid-resistant steel
Heat resistant steel and nickel alloys
High corrosion-resistant steel
Duplex and Super-duplex steel
