Corrosion-resistant steel for seawater suitable for high-temperature and high-humidity environment and method for manufacturing the same

摘要

The present invention relates to a steel material for marine vessels and a method of manufacturing the same, which are applied to a hot and humid environment, for example, a marine environment in which a ballast tank is exposed to seawater pipes and the like, or less, Mn: 1.50 wt% or less, Al: 0.005 to 0.050 wt%, Cr: 0.5 to 3.50 wt%, and the balance of Fe and inevitable impurities.
