WELD METAL ANALYSIS (RANGE) %
MECHANICAL PROPERTIES (RANGE)
• For shipbuilding.
• For the welding of structural steel where resistance to brittle fracture is required under adverse operating conditions such as those found in off-shore production platforms.
• Used for production of pressure vessels, bridges, pipelines recommended for higher carbon & higher Sulphur steels, which are susceptible to hydrogen induced cracking.
