- Pressure Vessel
- Dynamic Loaded structure
- Penstocks
- Blast furnace.
Description
MODI 7018 (NACE) is a low hydrogen controlled medium heavy coated iron powder type electrode, suitable for welding of medium-high tensile strength steels. The all-position electrode produces a smooth and stable arc, easily detachable slag and the least spatters. Metal recovery is a minimum of 110%. The welds have consistent radiography
quality. Welds metal displays excellent mechanical properties and excellent resistance to cold and hot cracking.
SPECIAL FEATURES: Apart from conforming to EIL Specification for Sour Services, GS 8-Annexure 1,
MODI 7018 (NACE) meets the requirements of: –1. Sulphide stress Corrosion Cracking test as per NACE Standard TM-01-77
2. Hydrogen Induced Cracking test as per NACE Standard TM-02-84.
Current Conditions: AC (70 OCV) / DC (+) |
