BS 970 (Part 3) 655M13 vs EN 10084 10NiCr5-4

Related Material — 68.8% match based on chemical composition and mechanical property overlap.

BS 970 (Part 3) 655M13 (BS 970 (Part 3):1991) and EN 10084 10NiCr5-4 (EN 10084:2008) are both steel grades. Both fall under the Alloy Steel category. BS 970 (Part 3) 655M13 is typically 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), while EN 10084 10NiCr5-4 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1). BS 970 (Part 3) 655M13 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 3) 655M13 vs EN 10084 10NiCr5-4 is a 68.8% 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 68.8%.
