BS 970 (Part 1) 637H17 vs EN 10084 10NiCr5-4

Related Material — 69.1% match based on chemical composition and mechanical property overlap.

BS 970 (Part 1) 637H17 (BS 970 (Part 1):1991) and EN 10084 10NiCr5-4 (EN 10084:2008) are both steel grades. Both fall under the Alloy Steel category. BS 970 (Part 1) 637H17 is typically used for case hardening steel (section four), while EN 10084 10NiCr5-4 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1). BS 970 (Part 1) 637H17 is defined under British Standards (BS), originating from United Kingdom, while EN 10084 10NiCr5-4 is defined under European Standard (EN), originating from Europe.

As per chemical composition, BS 970 (Part 1) 637H17 vs EN 10084 10NiCr5-4 is a 69.1% 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 69.1%.
