GB · China · 1 designation # 14Cr12Ni2WMoVNb 14Cr12Ni2WMoVNb is a grade designated under GB. Its recorded composition includes C 0.11–0.17%, Cr 11–12%, Ni 1.8–2.2%, Mo 0.8–1.2% and W 0.7–1%. No cross-standard equivalents are recorded for this grade yet. Further recorded physical values: λ 23–25.1 W/(m·K), α 9.9 ·10⁻⁶/K and cp 470 J/(kg·K); several of these are temperature-dependent. - *Designations* **1** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=40a2972c-3d95-41ab-b96d-2fa0a08a9ac8&designation=05215602-852b-4a37-b4a5-71d9f33b62b8 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gb/14cr12ni2wmovnb.pdf "Datasheet as PDF") ## Chemical composition 11 elements on file · weight % What this alloy is Fe Cr Ni Mo Iron — the balance, never listed by a standard — 82.8 % Cr — 11.5 % Ni — 2 % Mo — 1 % Traces & impurities · 2.7 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.11–0.17 | | Si | ≤ 0.6 | | Mn | ≤ 0.6 | | P | ≤ 0.03 | | S | ≤ 0.025 | | Cr | 11–12 | | Mo | 0.8–1.2 | | Ni | 1.8–2.2 | | V | 0.2–0.3 | | W | 0.7–1 | | Nb | 0.15–0.3 | Carbon Silicon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Vanadium Tungsten Niobium 0.01 % 0.1 % 1 % 10 % 100 % The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other. | Element | As published source text, verbatim | Min% by weight | Max% by weight | Bound | |---|---|---|---|---| | C | 0.11-0.17 | 0.110 | 0.170 | Range | | Si | ≤0.6 | — | 0.600 | Max | | P | ≤0.03 | — | 0.030 | Max | | S | ≤0.025 | — | 0.025 | Max | | V | 0.2-0.3 | 0.200 | 0.300 | Range | | Cr | 11-12 | 11.000 | 12.000 | Range | | Mn | ≤0.6 | — | 0.600 | Max | | Ni | 1.8-2.2 | 1.800 | 2.200 | Range | | Nb | 0.15-0.3 | 0.150 | 0.300 | Range | | Mo | 0.8-1.2 | 0.800 | 1.200 | Range | | W | 0.7-1 | 0.700 | 1.000 | Range | The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. 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 Thermal expansion coefficient 9.9 10^-6/K 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. ## Properties by condition 1 conditions · 3 values At temperature**no delivery state stated** source `caishuku` | Temperature °C | Thermal conductivity W/(m·K) | Specific heat capacity J/(kg·K) | |---|---|---| | 100 | 23 | — | | 500 | 25.1 | 470 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Heat treatment **GJB 2294** Order not stated by the source - Quenching Temperature not stated - Solution annealing 1150 °C Cooling Oil or Air - Tempering Temperature not stated - Ageing 570–600 °C Cooling Oil or Air The source lists these operations without stating an order or an alternation. They are shown unordered on purpose. Order not stated by the source - Quenching Temperature not stated - Solution annealing 1150 °C Cooling Oil or Air - Tempering Temperature not stated - Ageing 660–710 °C Cooling Oil or Air The source lists these operations without stating an order or an alternation.
