Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS420J1 (JIS G4304:2021) and GOST 5632 08X18H10 (GOST 5632-2014) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS420J1 is typically used for hot-rolled stainless steel plates and strips, while GOST 5632 08X18H10 is commonly used for chemical equipment, food processing, general corrosion resistant applications.
JIS G4304 SUS420J1 is defined under Japanese Industrial Standards (JIS) (Japan).
As per chemical composition, JIS G4304 SUS420J1 vs GOST 5632 08X18H10 is a 62.8% match.
As per mechanical properties, the match is 33.3%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
