Characterisation of Weld Metal for 3.5% Nickel Steel in Manual Metal Arc Welding and its Stress Corrosion and Low Cycle Corrosion Fatigue Propensities
Jump To References Section
Abstract
3.5% nickel steel possesses a combination of high strength and resistance to brittle fracture which makes it suitable to be widely used for the fabrication of storage tanks designed to be used at between 223K and 172K (pressure vessels to produce ethylene or propylene from naptha in chemical plant)[1-4].
