Stainless Steel Grade Equivalent Chart | AISI, EN, JIS, GB
This stainless steel grade equivalent chart helps international buyers compare common stainless steel names across ASTM / AISI, UNS, EN / DIN, JIS, and GB standards. It is built for procurement searches such as 304 equivalent grade, SUS304 equivalent, EN 1.4301 equivalent, 316 equivalent, and 2205 equivalent.
Important note
Equivalent does not always mean identical. Standards can differ by chemical limits, mechanical properties, product form, heat treatment, and inspection requirements. Use this table as a buying reference, then confirm the final grade with the project standard and mill test certificate.

FAQ
Is SUS304 the same as 304 stainless steel?
SUS304 is commonly compared with AISI 304 / UNS S30400, but final purchasing should confirm the applicable standard and certificate.
Is EN 1.4401 the same as 316?
EN 1.4401 is commonly compared with AISI 316 / UNS S31600. Confirm chemical and product standard requirements before substitution.
Can I replace one equivalent grade with another?
Not automatically. Equivalent tables are a starting point, not a substitute for engineering approval or MTC review.
