SUPRATHERME-R

AWS: SFA 5.1 E7018
EN ISO CODE:

Supratherme-R is a basic coated, Hydrogen controlled, Iron powder type high yield electrode. The electrode possesses excellent operating characteristics and is suitable for welding in all positions. Radiographic quality welds having high strength and excellent cracking resistance. Weld metal of excellent toughness to withstand heavy dynamic loading and impact. It is ideally suited for fabrication of component made of steels IS: 8500-91 Gr. 440B & 490B, IS: 2002-92 Gr. 1 & 2, IS: 1875-92 Class 2, 2A & 3, IS 2062-99 Gr. C or similar. Also suitable for repair welding of cast steels to IS: 1030 Gr. 230-450W. Supratherme-R also used for joining of stainless Steels type 3Cr12, IRS M- 44 or it's equivalent with Mild Steel / Low Alloyed Steel / Carbon Steel.
