高强度工程机械用钢应用现状和发展前景

The Application Status and Development of High Strength Steel for Engineering Machine

随着工程机械向装备大型化、轻量化及重载荷等方向的发展，高强度钢使用比例和质量要求都有较大提高。国内高强度工程机械用钢的研发及生产已取得快速进展，但在行业标准的统一制订、品种开发及产品质量等方面普遍存在差距。文章对目前国内工程机械用钢的需求发展趋势、国内供给情况及存在问题等进行了分析，为国内工程机械用钢的发展突破提供参考。

With the tendency of the engineering machinery to be large scale, lightweight and heavy load, the usage ratio and quality of the high strength steel have been greatly improved. Although rapid progress has been achieved in the research and production of the high strength engineering steel, there still existing some gaps in the industry standards, product development and quality, etc. Therefore, the development tendency, supply and demand status, existing problems of the engineering steel are introduced in this paper, which could serve as the references for the breakthrough development of the engineering steel.
