Overview

EN ISO 3506-6:2022 (adopted from ISO 3506-6:2020) provides general rules and technical information for selecting corrosion‑resistant stainless steels and nickel alloys suitable for the manufacture of fasteners. Published by CEN and aligned with the ISO 3506 series, this part is intended to be used together with Parts 1–5 of ISO 3506 to ensure appropriate material choice for bolts, screws, studs, nuts and special fasteners.

Key SEO phrases: EN ISO 3506-6:2022, ISO 3506-6:2020, stainless steel fasteners, nickel alloys, corrosion-resistant fasteners, selection rules.

Key Topics

This standard focuses on material selection criteria and properties relevant to fastener performance. Major technical topics include:

Groups and grades of stainless steels and nickel alloys (covers austenitic, martensitic, ferritic and duplex/austenitic‑ferritic types; grades such as A1–A8, C1–C4, F1, D2/D4/D6/D8 are categorized in the document).
Chemical composition specifications that determine corrosion resistance and mechanical behaviour.
Resistance to stress corrosion cracking - guidance on factors influencing susceptibility.
Resistance to pitting and crevice corrosion - assessment considerations for chloride environments.
Resistance to intergranular corrosion and avoidance strategies (e.g., material selection and heat treatment).
Susceptibility to intermetallic compound formation at elevated temperatures.
Magnetic permeability properties relevant for specific applications and testing.
Annex A: informative list of common designations of stainless steels and nickel alloys used for fasteners.

Applications

EN ISO 3506-6:2022 is practical for stakeholders who must specify, manufacture or test corrosion‑resistant fasteners:

Fastener manufacturers selecting appropriate grades and heat treatments.
Design and mechanical engineers specifying fasteners for structural, marine, chemical, oil & gas and construction projects.
Procurement and quality assurance teams ensuring material conformity with ISO 3506 series requirements.
Testing laboratories and certification bodies referencing material groups and corrosion‑related test guidance.
Standards committees and technical authors harmonizing product standards and datasheets.

This part helps ensure that chosen materials meet the environmental and mechanical demands of the application while remaining consistent with Parts 1–5 of ISO 3506.
