GOST 4543 15H2NM vs BS 970 (Part 3) 822M17

Close Alternative — 73.7% match based on chemical composition and mechanical property overlap.

GOST 4543 15H2NM (GOST 4543-2016) and BS 970 (Part 3) 822M17 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Alloy Steel category. GOST 4543 15H2NM is typically used for used for heavy-duty gears, shafts, couplings, bearings, and transmission parts., while BS 970 (Part 3) 822M17 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy case hardening steel (table 15). BS 970 (Part 3) 822M17 is defined under British Standards (BS) (United Kingdom).

As per chemical composition, GOST 4543 15H2NM vs BS 970 (Part 3) 822M17 is a 73.7% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a close alternative overall at 73.7%.
