We list 99 designations recorded for this grade, in the standards DIN / EN, AISI / SAE, BS, AFNOR, UNE, ISO, JIS, GB, GOST, UNI, SS, ČSN, STN, ABNT NBR, PN, MSZ, STAS, SANS, BDS, ÖNORM and NBN. - [*Material no.* **1.0036**](/materials/material-no/1.0036 "Material no.: 1.0036") - [*Category* **Unalloyed structural steels · 452 grades**](/categories/unalloyed-structural-steels "Category: Unalloyed structural steels · 452 grades") - *Designations* **99** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=9ca72cca-4eaa-49c0-a783-c4e2f99592b4&designation=084ada58-f734-4203-9fea-edaaf08652aa "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/s235jrg1.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN S235JR This grade’s own name · 4 grades on that route](/materials/din-en/s235jr "DIN / EN S235JR") ## About Unalloyed structural steels Unalloyed structural steels include all low-carbon steels in which the iron companions do not exceed specified minimum values. The yield strength, formability and weldability are the decisive factors for their use. They are soft, pliable, tough and stretchy, but cannot be hardened by heat treatment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 99 designations · 21 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. Superseded by the current name this withdrawn designation was replaced by — the same grade under its present designation, the one to order by today.
