GOST 1050 45 vs BS 970 (Part 1) 040A10

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

GOST 1050 45 (GOST 1050-2013) and BS 970 (Part 1) 040A10 (BS 970 (Part 1):1991) are both steel grades. Both fall under the Carbon Steel category. GOST 1050 45 is typically used for gears, shafts, spindles, bolts, axles, forged components, while BS 970 (Part 1) 040A10 is commonly used for used for bolts, studs, shafts, brackets, fabricated components, and general engineering parts.. BS 970 (Part 1) 040A10 is defined under British Standards (BS) (United Kingdom).

As per chemical composition, GOST 1050 45 vs BS 970 (Part 1) 040A10 is a 62.6% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a minimal match overall at 35%.
