Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GOST 5950 9HF (GOST 5950-2000) and GOST 5950 3H2W8F (GOST 5950-2000) are both steel grades.
Both fall under the Tool & Die Steels category.
GOST 5950 9HF is typically used for used for dies, punches, reamers, gauges, and woodworking cutters., while GOST 5950 3H2W8F is commonly used for used for forging dies, extrusion tools, hot punches, mandrels, and die inserts..
As per chemical composition, GOST 5950 9HF vs GOST 5950 3H2W8F is a 61.8% match.
As per mechanical properties, the match is 25%.
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.
