Abstract
The invention provides a high-efficacy metal material which is composed of the following materials in percentage by mass: 0.6-2.0% of C, 0.5-1.3% of Si, 0.8-1.5% of Mn, 0.01-0.03% of P, 0.002-0.01% of S, 1.5-8.5% of Ni, 18-28% of Cr, 0.5-2.5% of Cu, 0.1-1.0% of Al, 0.1-1.0% of Ti, 0.2-1.0% of at least one of rare-earth elements (Ce, La, Y and Sc), and the balance of Fe. The metal material is mainly composed of Fe and Cr, other metal elements capable of enhancing the properties, such as Mn, Ni and the like, are added, and a proper amount of rare-earth element is also added; and thus, compared with other metal materials, the metal material provided by the invention has the advantages of more balanced and excellent overall properties, favorable toughness, high wear resistance, high corrosion resistance, high plasticity, high weldability, high hardness and high strength.
Description
Technical field
The present invention relates to a kind of high-effect metallic substance.
Background technology
It is more extensive that current metallic substance interalloy metallic substance uses, and in general metallic substance, is elementary composition by C, Si, Fe etc. basically.These metallic substance can meet the general industry demand, but at some the field higher for the performance requriements of metallic substance, conventional metallic substance also can't satisfy the demands far away.The rare earth resources of China occupies forward position, the world, and rare earth element, due to himself distinctive performance, penetrates in iron and steel by it performance that can be good at improving iron and steel, and therefore, the research of rare earth aspect metallurgical industry at present starts more deep.But the rare earth element price general charged is more expensive, its amount added and with those combination of components all or the further target of research of needs.
