Duplex Stainless Steel Grades Comparison Chart
The table is intended to relate former BS, EN, German and Swedish grade designations to the current EN steel numbers, AISI grades and UNS (Unified Numbering System) numbers. The table is based on the 'wrought' ie long products (stainless steel bars etc), flat products (stainless steel plates sheet etc) steel numbers published in EN 10088 and related standards.
Castings products use different compositions and so have their own steel numbers in EN 10283. The related castings grades in both EN 10283 and BS 3100 are included in the table.
The 'Chemical Composition' is intended to represent the composition only. This does not show the specified or typical composition of commercially available steels. Specified ranges for the wrought European grades can be found in either the EN 10088-2 or EN10088-3 tables. None of the steels listed were included in either BS 970 or BS 1449. The castings grades specified ranges can be found in the EN 10283 or BS 3100 tables.
These are comparisons only and cannot be assumed to be direct equivalent grades. The data given is not intended to replace that shown in individual standards to which reference should always be made.
