GOST 1050 35 vs BS 970 EN14A

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

GOST 1050 35 (GOST 1050-2013) and BS 970 EN14A (BS 970:1955) are both steel grades. GOST 1050 35 is classified under Carbon Steel, while BS 970 EN14A is classified under Alloy Steel — a different category, which is worth noting alongside the chemistry match below. GOST 1050 35 is typically used for shafts, axles, connecting rods, forgings, gears, machine parts, while BS 970 EN14A is commonly used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable hardened and tempered for 40/50 (q) and 45/55 (r) tons/sq in according to ruling section; purchaser to state normalised, cold drawn or hardened and tempered q or r. when required as plate, sheet or strip order to bs 1449.. BS 970 EN14A is defined under British Standards (BS) (United Kingdom).

As per chemical composition, GOST 1050 35 vs BS 970 EN14A is a 76.2% match. As per mechanical properties, the match is 45%. Combined, this makes them a related material overall at 65%.
