SAE AMS · United States / Aerospace · 15 designations # 5934 5934 is a designation in SAE AMS for the material held under material number 1.4534, also listed as X3CrNiMoAl13-8-2. It is a material in the category Special steels for aviation and aerospace. We list 15 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, ASTM and SAE AMS. - [*Material no.* **1.4534**](/materials/material-no/1.4534 "Material no.: 1.4534") - [*Category* **Special steels for aviation and aerospace · 39 grades**](/categories/special-steels-for-aviation-and-aerospace "Category: Special steels for aviation and aerospace · 39 grades") - *Designations* **15** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=37bb930c-bdd8-4efd-9904-3fed0b116194&designation=0a0f920d-ee36-4494-8e00-443e9d411604 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/ams/5934.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X3CrNiMoAl13-8-2 This grade’s own name](/materials/din-en/x3crnimoal13-8-2 "DIN / EN X3CrNiMoAl13-8-2") - [UNS S13800 This grade’s own name](/materials/uns/s13800 "UNS S13800") - [AISI / SAE XM-13 This grade’s own name](/materials/aisi-sae/xm-13 "AISI / SAE XM-13") ## About Special steels for aviation and aerospace Special steels for aviation and aerospace are engineered steels designed to provide controlled mechanical properties and reliable performance in demanding service. Their alloying and heat-treatment capabilities support components that require a combination of strength, toughness and fatigue resistance, including aircraft structures and engine parts. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 15 designations · 5 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures This grade's composition falls outside the published model's validated range (a low-alloy composition window), so no transformation temperature is predicted here. ## Physical & mechanical properties Density 7,85 g/cm³ Exact An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Looking for this grade under another name?
