GB · China · 5 designations # 00Cr17Ni13Mo2N 00Cr17Ni13Mo2N is a designation in GB for the material held under material number 1.4909, also listed as X2CrNiMoN17-12-2. It is a material in the category High-temperature steels. We list 5 designations recorded for this grade, in the standards DIN / EN, UNS, AFNOR, JIS and GB. - [*Material no.* **1.4909**](/materials/material-no/1.4909 "Material no.: 1.4909") - [*Category* **High-temperature steels · 40 grades**](/categories/high-temperature-steels "Category: High-temperature steels · 40 grades") - *Designations* **5** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=6a368948-888e-41c3-84e3-8ea40963b475&designation=71138bf8-6a20-4f29-bf5f-86794aae32e4 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/00cr17ni13mo2n.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN X2CrNiMoN17-12-2 This grade’s own name · 2 grades on that route](/materials/din-en/x2crnimon17-12-2 "DIN / EN X2CrNiMoN17-12-2") ## About High-temperature steels High-temperature steels are steels designed to retain useful strength and structural stability during exposure to elevated temperatures. Their alloying systems provide resistance to oxidation, creep and loss of mechanical properties during prolonged heating, making them suitable for furnace components, heat exchangers, boilers and other hot-service equipment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 5 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 Elastic modulus 200 GPa Exact Thermal expansion coefficient 15 10^-6/K Exact Thermal conductivity 15 W/(m·K) Exact Specific heat capacity 0.5 J/(kg·K) Exact Electrical resistivity 0.75 nΩ·m 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. ## Heat treatment Supply condition - Solution annealing d≤180 Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.

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