产品简介：低合金钢焊条包括抗拉强度500MPa级以上的低合金高强钢焊条，耐热钢焊条和低温钢焊条。低合金的焊接一般依钢材的强度等级来选用相应的焊条，对于碳钢与低合金钢或者低合金与低合金钢之间的异种钢焊接。一般选用与强度等级较低的钢材相应的焊接材料（焊条或焊丝）。详细描述牌号\\化学成分 C Mn Si Ni Cr Cu W Mo V S P J502NiCu ≤0.1 0.3-0.8 ≤0.3 0.2-0.5 0.2-0.3 0.15-0.4 ≤0.035 ≤0.035 J502WCu ≤0.12 0.5-0.9 ≤0.3 0.2-0.5 0.2-0.5 ≤0.030 ≤0.030 J502CrNiCu ≤0.1 0.45-0.75 ≤0.3 0.35-0.45 0.25-1.45 0.1-1.3 ≤0.030 ≤0.030 J506WCu ≤0.12 0.6-1.2 ≤0.35 0.2-0.5 0.2-0.5 ≤0.030 ≤0.030 J506R ≤0.1 ≤1.5 ≤0.5 ≤0.7 ≤0.030 ≤0.030 J506RH ≤0.1 ≤1.6 ≤0.5 0.35-0.8 ≤0.025 ≤0.025 J506NiCu ≤0.12 0.5-1.2 ≤0.7 0.2-0.5 0.2-0.4 ≤0.03 ≤0.035 J506NiCrCu ≤0.1 0.45-1.0 ≤0.5 0.15-0.5 0.2-1.45 0.1-1.3 ≤0.03 ≤0.030 J507NiCu ≤0.12 0.5-1.2 ≤0.7 0.2-0.5 0.2-0.4 ≤0.03 ≤0.035 J507WCu ≤0.1 0.6-1.2 ≤0.35 0.2-0.5 ≤0.03 ≤0.030 J507RH ≤0.12 ≤1.6 ≤0.5 0.3-0.8 ≤0.025 ≤0.025 J507Mo ≤0.12 ≤0.9 ≤0.6 0.4-2 ≤0.2 ≤0.035 ≤0.035 J507MoW ≤0.1 ≤0.8 ≤0.5 Nb≤0.12 0.5-0.9 ≤0.2 J507CrNi ≤0.1 0.5-0.8 0.3-0.5 0.2-0.5 0.5-0.8 0.2-0.5 0.2-0.5 ≤0.035 ≤0.035 J507FeNi ≤0.08 0.8-1.3 ≤0.65 1.2-2.0 ≤0.030 ≤0.030 J606 ≤0.12 1.2-1.75 ≤0.6 0.25-0.45 ≤0.035 ≤0.035 J607RH ≤0.1 ≥1.0 ≤0.8 0.6-1.2 0.5-0.9 0.1-0.4 ≤0.025 ≤0.025 J607Ni ≤0.1 ≥1.0 ≤0.8 1.2-1.5 ≤0.03 ≤0.035 J707Ni ≤0.1 ≥1.0 ≤0.6 1.8-2.2 ≤0.2 0.4-0.6 ≤0.03 ≤0.030 J857Cr ≤0.15 ≥1.0 ≤0.6 0.2-1.1 0.5-1.0 ≤0.15 ≤0.035 ≤0.035 J857CrNi ≤0.1 1.3-2.5 ≤0.6 1.75-2.5 0.3-1.5 0.3-0.55 ≤0.05 ≤0.03 ≤0.04 J907 ≤0.2 1.4-2.0 0.4-0.8 0.8-1.2 ≤0.035 ≤0.035 J907Cr ≤0.15 ≥1.0 ≤0.8 0.7-1.1 0.5-1.0 0.05-0.15 ≤0.035 ≤0.035 J107 ≤0.2 ≥1.0 0.3-0.8 0.3-0.6 ≤0.035 ≤0.035 J107Cr ≤0.15 ≥1.0 0.3-0.8 1.5-2.2 0.4-0.8 0.05-0.15 ≤0.035 ≤0.035
