SUPERLET – 18 NACE
SUPERLET – 18 NACE
(Basic Coated Low Hydrogen Iron Powder type Electrode for NACE Application)
DESCRIPTION AND APPLICATIONS: SUPERLET – 18 NACE having basic flux covering contains iron powder that provides tough & crack free weld deposits highly resistant from hydrogen induced cracking. The electrode has ease of operation in all position on AC/DC(+), smooth & stable arc, easy to strike & re-strike, low spatter and easy slag detachability. Welds are of radiographic quality. Highly suitable for welding of carbon steel in fabrication of machinery & equipment of a wide range, especially for structure which are designed for severe service condition involving heavy stresses and dynamic loads. It finds numerous applications with grain-refined constructional steels having tensile strength in the range 500 to 600 N/mm2.
TYPICAL APPLICATIONS: Boilers, Bridges, Penstocks, Pumps and Compressors, Off-shore drilling rings & platforms, Pressure Vessels, Frigates & Submarines, Blast furnace shells, Rotary Kiln Shells, Rail wagons & coaches etc. SUPERLET – 18 NACE meets the requirements of sulphide stress corrosion cracking test and Hydrogen induced cracking test as per NACE standard.
Precautions:
- Store in a dry place.
- Redry the electrodes at 250°C for one hour before use and place the baked electrodes in carrying oven at 90oC while in use.
- Maintain appropriate current and short arc.
- Remove oil, grease, dust & rust from parent metal.
- Do not handle the electrodes with moisture greasy hand.
