Close Alternative — 82.1% match
based on chemical composition and mechanical property overlap.
GB/T 699 35 (GB/T 699:2015) and GOST 1050 35 (GOST 1050-2013) are both steel grades.
Both fall under the Carbon Steel category.
GB/T 699 35 is typically used for used for shafts, connecting rods, bolts, forged parts, gears, and machine components., while GOST 1050 35 is commonly used for shafts, axles, connecting rods, forgings, gears, machine parts.
GB/T 699 35 is defined under Guobiao Standards (GB/T) (China).
As per chemical composition, GB/T 699 35 vs GOST 1050 35 is a 98.2% match.
As per mechanical properties, the match is 50%.
Combined, this makes them a close alternative overall at 82.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
