Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
AISI 52100 and GOST 5950 4H5MFS1 (GOST 5950-2000) are both steel grades.
Both fall under the Tool & Die Steels category.
AISI 52100 is typically used for anti-friction bearings, ball screws, precision rollers, while GOST 5950 4H5MFS1 is commonly used for used for forging dies, pressure casting dies, hot punches, extrusion tooling, and die inserts..
AISI 52100 is defined under AISI (United States).
As per chemical composition, AISI 52100 vs GOST 5950 4H5MFS1 is a 59.5% 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.
Used for forging dies, pressure casting dies, hot punches, extrusion tooling, and die inserts.
