CROMOTHERME-1(MOD)
AWS: SFA 5.5 E8018-B2
EN ISO CODE: 3580-A E CrMo1 B 4 2 H5
Weld metal having lesser impurities i.e. S, P, will improve the subzero impact property and retains its mechanical properties after prolonged heat treatments. Ideal for welding similar composition materials. The weld metal displays excellent tensile strength and creep resistance. Specially applicable wherever the impact o property requirement at subzero temperatures up to minus 20 C.
