一、06AlNbcuN 钢钢管低温试验杭州钢铁厂应燃化部有关单位的要求,在冶金部支持下进行06AlNbCuN 钢钢管的生产。1.钢管的化学成分(炉号3—44)% 2.钢管常温机械性能(910℃正火)σ_skg/mm~2 σ_bkg/mm~2 δ_5% 压扁4S35～39 46～48.5 32.5～35.5 合格3.低温冲击性能试样取自φ78×6毛管,试样为10×5×55mm,正火温度920℃。其-120℃冲击值如下:kg-m/cm~215.5,15.7,16.0,17.0,17.7。
First, 06AlNbcuN steel pipe cold test Hangzhou Steel Plant should be required by the relevant units of the Ministry of the Ministry of the Ministry of Metallurgical 06AlNbCuN steel pipe production. 1. The chemical composition of steel pipe (Hearth No. 3-44)% 2. Mechanical properties of steel pipe at normal temperature (normalizing at 910 ℃) σ_skg / mm ~ 2 σ_bkg / mm ~ 2 δ_5% Squashed 4S35 ~ 39 46 ~ 48.5 32.5 ~ 35.5 Pass 3. Low-temperature impact properties of samples taken from φ78 × 6 capillary, the sample was 10 × 5 × 55mm, normalizing temperature of 920 ℃. The -120 ℃ impact value is as follows: kg-m / cm ~ 215.5,15.7,16.0,17.0,17.7.
