Electrodes for Creep Resisting Steels

CROMOTHERME-2(15)RTE

AWS: SFA 5.5 E9015-B3

EN ISO CODE:

Weld metal having strict control on S, P, As, Sn & Sb will improve the sub-zero impact property and resists temper embrittlement. Weld metal retains its mechanical properties after prolonged heat treatments. Ideal for welding steam generating equipments and reactor vessels. The weld metal displays excellent tensile strength and creep resistance. Specially applicable wherever temper embrittlement resistance is required.
