Minimal Match — 49.6% match
based on chemical composition and mechanical property overlap.
IS 6911 X20Cr25Ni20 (IS 6911:1992) and GB/T 3280 06Cr19Ni10 (GB/T 3280-2015) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X20Cr25Ni20 is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while GB/T 3280 06Cr19Ni10 is commonly used for used for kitchen equipment, food processing machinery, chemical tanks, piping, architectural panels, and fasteners..
IS 6911 X20Cr25Ni20 is defined under Bureau of Indian Standards (IS), originating from India, while GB/T 3280 06Cr19Ni10 is defined under Guobiao Standards (GB/T), originating from China.
As per chemical composition, IS 6911 X20Cr25Ni20 vs GB/T 3280 06Cr19Ni10 is a 74.3% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 49.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
