INFLUENCE MOLYBDENUM ON THE CORROSION-MECHANICAL PROPERTIES OF CARBON STEEL WELDED JOINTS
Journal Title: Проблеми тертя та зношування - Year 2017, Vol 75, Issue
Abstract
The paper studies the impact of molybdenum on the corrosion and mechanical properties of welded joints of steel boiler. Found that the most high and stable toughness values and resistance to cracks and sulfide stress corrosion cracking of the weld metal pipe steels are achieved when the concentration of molybdenum in it from 0.2 to 0.3%, which implemented in electrode input molybdenum powder coating in an amount of 0.5-1.0%. The optimum chemical composition of weld metal provides getting fine-grained structure, holding a small amount of non-metallic inclusions of globular form.
