船舶是在海洋环境中航行的大型结构物,一般要求其有很高的安全性,包括其使用的钢材要有很高的强度。为提高产品竞争力、性能和加工生产效率,钢铁生产者从设计和加工两个方面对钢材都投入了很大的力量。特别是钢铁材料作为船体结构的主要材料,在有关强度可靠性和加工性上期待着更高功能钢材的开发研制和应用。 Ships are large structures navigating in the marine environment and generally require a high level of safety, including the high strength of steel used. To improve product competitiveness, performance and processing productivity, steel producers have invested heavily in steels both in design and fabrication. In particular, as the main material of the hull structure, the steel material is expected to be developed and applied to the development of higher-functional steel in terms of strength, reliability and workability.
