Sanicro 69 是一种碱性药皮焊条，用于大多数低合金钢和不锈钢上耐腐蚀堆焊。它还用于合金 690 型的合金，例如Sanicro 69 和异种接头的焊接。该焊条具有优良的焊接性能，非常适合接头焊接以及堆焊。STANDARDS– ISO 14172: Ni 6152– AWS A5.11/ASME SFA-5.11: ENiCrFe-7APPLICATIonSIt is used for welding of alloys of Alloy 690 type (e.g. Sanicro 69) and dissimilar joints. It is also used for overlaywelding in the nuclear industry used primarily for steam generators in nuclear power plants (PWR). For this application the material is characterized by extremely high stress corrosion resistance in primary side PWR water conditions. Sanicro 69 also has improved pitting resistance in chloride containing solutions compared to alloy 600.Sanicro 69 is characterized by excellent resistance to nitric acid. Furthermore, the material shows very goodresistance to high temperature oxidation. 焊缝金属特征以下数据对非热处理的全焊缝金属有效。C Si Mn P S Cr Ni Mo Fe Nb化学成分，wt%≤0.040 0.5 2.4 ≤0.015 ≤0.≤0.3 9 1.6微观组织 - 全焊缝金属全奥氏体机械性能温度 C (°F) 20 (68) 360 (680)*屈服强度，R MPa (ksi) 420 (61) 330 (48)抗拉强度，R MPa (ksi) 650 (94) 520 (75)延伸率，A % 43 39冲击强度，夏比 V 型 J (ft lb) 115 (85) -R 对应于 0.2% 塑型变形的屈服强度o bP0.2ama p0.2b 610°C 下焊后热处理 16 h 后。耐腐蚀性能抗晶间应力腐蚀开裂性。制造直径，mm (in.) 电流，A2.50 (~3/32) 50-703.25 (~1/8) 70-1004.00 (~5/32) 105-145必要时重新烘干焊条：200°C (390°F)/2 hPRODUCTIVITY DATAElectrode diameter, mm (in.) 2.50 (~3/32) 3.2 (~1/8) 4.00 (~5/32)Length, mm (in.) 300 (~12) 350 (~14) 350 (~14)Deposition ratekg weld metal/h (approx.) ≤0.9 ≤1.4 ≤2.2lb weld metal/h (approx.) ≤2.0 ≤3.1 ≤4.9Effective valuekg weld metal/kg electrodes 0.66 0.69 0.67lb weld metal/lb electrodes 0.66 0.69 0.67Change valueElectrodes/kg weld metal 94 49 30Electrodes/ lb weld metal 43 23 14Burn-off time per electrode at max current, s 46 59 76
