BS 970 (Part 3) 420S37 vs GOST 5632 08X18H10

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

BS 970 (Part 3) 420S37 (BS 970 (Part 3):1991) and GOST 5632 08X18H10 (GOST 5632-2014) are both steel grades. Both fall under the Stainless Steel category. BS 970 (Part 3) 420S37 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; martensitic stainless steel (table 17), while GOST 5632 08X18H10 is commonly used for chemical equipment, food processing, general corrosion resistant applications. BS 970 (Part 3) 420S37 is defined under British Standards (BS) (United Kingdom).

As per chemical composition, BS 970 (Part 3) 420S37 vs GOST 5632 08X18H10 is a 62.8% 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%.
