Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
AISI D2 KNL (ASTM A681) and EN ISO 4957 1.2316 (EN ISO 4957:2018) are both steel grades.
Both fall under the Tool & Die Steels category.
AISI D2 KNL is typically used for blanking dies, forming dies, thread rolling dies, punches, shear blades, gauges, broaches, drawing dies, while EN ISO 4957 1.2316 is commonly used for plastic injection moulds for corrosive materials, food packaging moulds.
AISI D2 KNL is defined under AISI, originating from United States, while EN ISO 4957 1.2316 is defined under European Standard (EN), originating from Europe.
As per chemical composition, AISI D2 KNL vs EN ISO 4957 1.2316 is a 73% match.
As per mechanical properties, the match is 0%.
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.
