Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The A572 Gr 60 ms steel coil, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.
According to the latest statistics of alacero, the consumption of finished steel A572 Gr 60 ms steel coil products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.
The characteristic of niobium in A572 Gr 60 ms steel coil etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.
The latest oil market forecast presented by the International Energy Agency (IEA) in its March report shows that as the impact of COVID-19 spreads globally, travel and broader economic activity are limited, global oil demand is expected to decline in 2020. As the current situation remains uncertain, this has created great uncertainty in assessing the global impact of the epidemic. In the core foundation forecast of the IEA, the sharp shrinkage of China’s oil consumption, coupled with severe disruptions in global tourism and trade, will cause global oil demand to decline for the first time since 2009.
