International Standards Reference Index
ISO Standards for Industrial Materials
A procurement-focused index for hardmetals, stainless and duplex steels, corrosion-resistant alloys, metallic-material testing and inspection documentation.
Reference policy
Verified Editions, Official Access and Scope Control
This index contains original MNK-G.S.A summaries and links to official ISO catalogue records. Protected standard text, tables, limits and acceptance criteria are not reproduced.
Standard identity, edition, publication status, material grade, product form, test method and inspection requirements must be verified for every inquiry. “Under review” and “revision planned” indicate that a fresh ISO catalogue check is required before quotation or order placement.
References that collect designations from several systems do not, by themselves, establish grade equivalence. Equivalence must be demonstrated through the governing specification, manufacturer data and inspection documents.
Hardmetals and cemented carbides
ISO References for Hardmetals and Cemented Carbides
These standards support classification, microstructural assessment, density, mechanical testing and application of WC-Co and related hardmetal families. They do not replace the customer’s grade specification, drawing or application-specific acceptance criteria.
