Material Grade Finder
This stainless steel material grade finder helps buyers compare AISI, EN, JIS, GB and related grade references during sourcing.
This stainless steel material grade finder helps buyers convert local grade names into common international references. Search by AISI, ASTM, UNS, EN, DIN, JIS, GB, AFNOR, BS, Spanish, Portuguese, or Vietnamese wording such as SUS304, EN 1.4301, 06Cr19Ni10, acero inoxidable 304, aço inox 304, or inox 304.
Important: equivalent does not always mean identical. Use this tool as a procurement reference, then confirm the final product standard, chemical composition, mechanical properties, heat treatment, dimensions, surface finish, and mill test certificate.

Why this tool can attract search traffic
Many international buyers do not search only in English. A Spanish buyer may search equivalencia acero inoxidable 304, a Brazilian buyer may search equivalência aço inox 316, and a Vietnamese buyer may search inox 304 tương đương tiêu chuẩn nào. A searchable tool can cover these long-tail terms while sending users to related grade guides, comparison pages, calculators, and quote forms.

Frequently Asked Questions
Frequently Asked Questions
No. Equivalent tables and search tools are procurement references. Final substitution should be confirmed by the project standard, mill test certificate, chemical limits, mechanical properties, and application conditions.
Yes. The finder includes local-language buying terms such as acero inoxidable, acero inox, aço inox, chapa inox, inox 304, and tấm inox.
Different standards systems developed their own grade names, material numbers, and steel names. International procurement often needs to map AISI, UNS, EN, DIN, JIS, GB, and local market wording.
