We list 21 designations recorded for this grade, in the standards DIN / EN, AISI / SAE, BS, AFNOR, UNE, JIS, GOST, UNI, ČSN, PN, SRPS, MSZ, STAS and BDS. - [*Material no.* **1.5732**](/materials/material-no/1.5732 "Material no.: 1.5732") - [*Category* **Case hardening steels · 60 grades**](/categories/case-hardening-steels "Category: Case hardening steels · 60 grades") - *Designations* **21** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c6380f05-76e9-4aa4-87fc-8d212acf7b88&designation=a1bc4e8a-66f2-4de1-8821-f5c3d78964cd "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/stas/13crni30q.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [AISI / SAE 3415 This grade’s own name · 4 grades on that route](/materials/aisi-sae/3415 "AISI / SAE 3415") ## About Case hardening steels Case hardening steels are steels designed to develop a hard, wear-resistant surface while retaining a tough and ductile core. They are used for components such as gears, shafts and other machine parts exposed to contact wear and cyclic loading. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 21 designations · 14 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Looking for this grade under another name?
