BS 970 EN36C vs EN 10084 14NiCrMo13-4

Close Alternative — 80.4% match based on chemical composition and mechanical property overlap.

BS 970 EN36C (BS 970:1955) and EN 10084 14NiCrMo13-4 (EN 10084:2008) are both steel grades. Both fall under the Alloy Steel category. BS 970 EN36C is typically used for used for gears, camshafts, pinions, heavy-duty shafts, aerospace transmission parts, and worm drives., while EN 10084 14NiCrMo13-4 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1). BS 970 EN36C is defined under British Standards (BS), originating from United Kingdom, while EN 10084 14NiCrMo13-4 is defined under European Standard (EN), originating from Europe.

As per chemical composition, BS 970 EN36C vs EN 10084 14NiCrMo13-4 is a 80.4% 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 80.4%.
