[ 热 307 ]
钼珠光体耐热钢焊条
说 明：SH·R307系低氢钠型药皮的含1.25%Cr - 0.5%Mo的珠光
体耐热钢焊条。采用直流反接，焊条接正极，短弧操作，可进行全位置
焊接。焊前焊件需预热至160℃- 220℃。
用 途：用于焊接工作温度在520℃以下的1. 25%Cr -0.5%Mo（如
15CrMo)耐热钢，如锅炉管道、高压容器、石油精炼设备等。也可用来
焊接30CrMnSi铸钢。
熔敷金属化学成分(%)
熔敷金属力学性能（620℃×1h 回火处理)
药皮含水量：≤0.30%
X射线探伤要求：I 级
焊接时参考电流：DC+
1．焊前焊条须经350℃烘焙1h，随烘随用。 2．焊前必须对焊件清除铁锈、油污、水分等杂质。 |
