Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 EN29A (BS 970:1955) and NF A35-565 100C6 are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN29A is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for r, s, t, u, v, w, z (45/55 to 100 tons/sq in); selection of en 29a or 29b governed by the tensile range required., while NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
BS 970 EN29A is defined under British Standards (BS), originating from United Kingdom, while NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF), originating from France.
As per chemical composition, BS 970 EN29A vs NF A35-565 100C6 is a 58.9% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
