Highly corrosion-resistant stainless steels
Stainless steel 1.4539 and 1.4529 A8 demonstrate a higher level of resistance to corrosion and acid (HCR) than A2 or A4 stainless steels.
Fasteners made of A5 are used in atmospheres containing chlorine, such as indoor swimming pools, or in coastal areas directly affected by spray water, for example boat jetties.
Stainless steel A8 1.4529 (also known as super austenitic stainless steel) is an enhanced version of the material 1.4539 and is characterised by its particularly high resistance (CRC V) to localised types of corrosion, such as chlorine-induced crevice, stress or pitting corrosion. Furthermore, it has good polishing and mechanical properties and can be used in a wide range of temperatures. For this reason, the use of this material to fasten load-bearing components is mandatory in certain sectors.
The materials have technical approval from the Deutsches Institut für Bautechnik (DIBt, national approval no. Z-30.3-6, dated 05/03/2018).
This approval states that the use of stainless steel with CRC class V, such as our 1.4529 material, is recommended or may even be mandated for load-bearing fasteners, connectors and threaded parts.
Additional key mechanical properties for corrosion-resistant connectors can be found in the following currently applicable standards: DIN EN ISO 3506-1:2020-08 for screws, DIN EN ISO 3506-:2020-08 for nuts and in the first edition of ISO 3506-6:2020-04.
