We list 82 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, BS, AFNOR, UNE, ISO, JIS, GB, GOST, SS, ČSN, COPANT, PN, MSZ, STAS, BDS and KS. - [*Material no.* **1.1167**](/materials/material-no/1.1167 "Material no.: 1.1167") - [*Category* **Quenched and tempered steels · 133 grades**](/categories/quenched-and-tempered-steels "Category: Quenched and tempered steels · 133 grades") - *Designations* **82** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=52da3cd7-2ee1-4cfd-a16b-f006302825af&designation=c50b47b4-e546-4383-8026-337ac8b16533 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/une/f-8212.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 36Mn5 This grade’s own name](/materials/din-en/36mn5 "DIN / EN 36Mn5") - [UNS G13350 This grade’s own name · 2 grades on that route](/materials/uns/g13350 "UNS G13350") - [AISI / SAE 1335 This grade’s own name · 2 grades on that route](/materials/aisi-sae/1335 "AISI / SAE 1335") ## About Quenched and tempered steels Quenched and tempered steels are heat-treated steels designed to combine high strength with useful toughness and ductility. They are used for heavily loaded components such as shafts, gears, fasteners and structural machine parts where resistance to mechanical stress is required. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 82 designations · 18 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
