Description:

Elgatig 185CR is a 5.8% Cr/0.5% Mo alloyed wire intended for TIG welding creep resisting steels of

matching composition, used widely in chemical and petrochemical plant because of their excellent

resistance to hydrogen attack and corrosion by high sulphur crude oils at service temperatures up to

650°C, e.g. DIN 12 CrMo 19 5, BS 3604 Grades HFS 625 and CFS 625, ASTM A155 Grade 5Cr etc.

To avoid hydrogen cracking, preheat and interpass temperature of 250-300°C must be carefully

controlled. Maintain preheat for some time after completion of welding. Post-weld heat treat at 750°C.
