Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10028-2 P355GH (EN 10028-2:2017) and BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10028-2 P355GH is typically used for flat products for pressure purposes, while BS 970 (Part 1) 040A04 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
EN 10028-2 P355GH is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 040A04 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10028-2 P355GH vs BS 970 (Part 1) 040A04 is a 45% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
