GOST 1050 45 vs SAE J404 50B46

Related Material — 65% match based on chemical composition and mechanical property overlap.

GOST 1050 45 (GOST 1050-2013) and SAE J404 50B46 (SAE J404:2009) are both steel grades. GOST 1050 45 is classified under Carbon Steel, while SAE J404 50B46 is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. GOST 1050 45 is typically used for gears, shafts, spindles, bolts, axles, forged components, while SAE J404 50B46 is commonly used for chemistry-only alloy steel grade; see the composition notes for product scope. SAE J404 50B46 is defined under SAE International (United States).

As per chemical composition, GOST 1050 45 vs SAE J404 50B46 is a 73.2% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a related material overall at 65%.
