Electrodes for Creep Resisting Steels

CROMOTHERME-2L(RTE)

AWS: SFA SFA 5.5 E8018-B3L

EN ISO CODE:

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