ES 502 - 15 A5.5: E 8015-B6 / EN 1599: E CrMo5 B 42 H5

Description

ES 502 - 15 is an LMA electrode containing 5Cr0.5Mo for welding creep-resistant steels. It is especially suitable for pipe welding. The electrode runs with a quiet, stable arc and gives a minimum amount of spatter loss. A preheating and interpass temperature of 150-260°C is normally required. The mechanical properties stated here are afterone hour of heat treatment at 740°C. Redrying temperature, 350°C , Redrying time,2 hours, Recovery115
