TS ISO 6372

TS ISO 6372 is a terminology standard for nickel and nickel alloys. It brings together the definitions used to describe this family of materials, helping engineers, producers, purchasers and technical writers use the same terms with the same meaning. Its subject is not limited to the alloy family as a general idea; it also addresses refinery products, as well as wrought products and castings, which are important distinctions in metalworking and materials specification.

How the terminology is organised

According to the scope, the defined terms are grouped around three main areas: materials, refinery products, and wrought products and castings. In metallurgy, that separation matters because the same base alloy may appear in different product forms, at different stages of processing, and with different names depending on how it is made and supplied. A terminology standard helps remove ambiguity by fixing the meaning of those labels.

In general technical context, nickel and nickel alloys are valued for properties such as corrosion resistance, high-temperature performance, and stable behaviour in demanding environments. For that reason, clear terminology is essential when describing composition, product form, processing stage and intended use. This standard supports that clarity by defining the vocabulary used across the nickel and nickel alloy field.

• Provides a common naming framework for nickel and nickel alloy materials.
• Distinguishes refinery products from other metallurgy intermediate forms.
• Covers terms for wrought products and castings as separate product forms.
• Supports consistent technical communication across the nickel materials field.
