EN 10084 20NiCrMo13-4 vs BS 970 (Part 1) 832H13

Related Material — 67.7% match based on chemical composition and mechanical property overlap.

EN 10084 20NiCrMo13-4 (EN 10084:2008) and BS 970 (Part 1) 832H13 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Alloy Steel category. EN 10084 20NiCrMo13-4 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while BS 970 (Part 1) 832H13 is commonly used for case hardening steel supplied to specified hardenability limits (end quench test, table 10).. EN 10084 20NiCrMo13-4 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 832H13 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, EN 10084 20NiCrMo13-4 vs BS 970 (Part 1) 832H13 is a 67.7% 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 67.7%.
