Sanicro 71 是一种具有正常金属回收率的碱性药皮焊条，用于焊接 NiCrFe 合金、9% Ni 钢以及用于低温环境的镍合金钢。它还用于异种接头，例如，不锈钢和 NiCu 合金与碳钢和镍合金之间的焊接。Sanicro 71 具有以下特点：低飞溅 和良好的脱渣性。STANDARDS产品认证– ISO: 14172: Ni6182– AWS A5.11/ASME SFA-5.11: ENiCrFe-3– W.Nr.: 2.4807– TÜVAPPLICATIonSApplications for Sanicro 71 are found in constructions to be used at low temperature; e.g. Ni-steel with a Cr content of 3.5 %, 5 % and 9 % are used as well as austenitic Cr-Ni stainless steel, especially if the weld metal is to be thermoformed or stress relieved.Sanicro 71 is suitable for joining nickel alloys such as:The alloy can be used in air up to 1200°C (2150°F), in sulphur dioxide atmospheres up to 800°C (1470°F) and in ammonia at the highest process temperature. This alloy is used for surfacing or joining where there are strict re on stress corrosion resistance and for high temperature service.®®– Sandvik Sanicro 30 (UNS N08800, EN 1.4558, mod Alloy 800) ®– Sandvik Sanicro 31H (UNS N08810, EN 1.4958, Alloy 800H) ®– Sandvik Sanicro 70 (UNS N06600, EN 2.4816, Alloy 600) ®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 Nb Fe Cu化学成分，wt%≤0.05 ≤1.0 6.5 ≤0.015 ≤0.≤1.5 2.5 ≤10 ≤0.5微观组织全焊缝金属全奥氏体。机械性能温度 C (°F) 20 (68) -196 (-320)屈服强度，R MPa (ksi) >360 (52) -抗拉强度，R MPa (ksi) >620 (90) -延伸率，A % >30 -冲击强度，夏比 V 型 J (ft lb) >60 (44) >45R 对应于 0.2% 塑型变形的屈服强度oP0.2ama p0.2耐腐蚀性能根据 ASTM A262 practice E，在“焊态”、应力消除和固溶退火状态下的抗晶间腐蚀性。制造直径，mm (in.) 电流，A2.50 (~3/32) 45-603.25 (~1/8) 70–954.00 (~5/32) 90-1205.00 (~3/16) 120-150必要时重新烘干焊条：200°C (390°F)/2 h生产率数据焊条直径，mm (in.) 2.50 (~3/32) 3.25 (~1/8) 4.00 (~5/32) 5.00 (~3/16)长度，mm (in.) 300 (~12) 350 (~14) 350 (~14) 350 (~14)重量kg (lb)/100 pcs 1.7 (3.7) 2.9 (6.4) 5.0 (11) 8.7 (19.1)kg (lb)/箱 4.5 (9.9) 4.6 (10.1) 5.3 (11.7) 5.2 (2.4)焊条数/箱 8有效值kg 焊缝金属/kg 焊条 0.61 0.71 0.68 0.67lb 焊缝金属/lb 焊条 0.61 0.71 0.68 0.67变化值焊条/kg 焊缝金属 94 49 29 16焊条/lb 焊缝金属 43 23 13 7每根焊条在最大电流下的熔化时间 (s) 46 59 76 101工作数据焊接位置， 除立向下焊之外的所有焊接位置电流/极性 直流电/焊条正极。
