Description

A kind of new two phase stainless steel
Technical field
The present invention relates to the industry of Steel material, relates in particular to a kind of new two phase stainless steel.
Background technology
The general not resistant to chemical media of common stainless steel corrodes, and acid resisting steel then generally has rustless property, " stainless steel " one Word not exclusively refers to merely a kind of stainless steel, but represents more than the 100 industrial stainless steels of kind, and the every kind of stainless steel capital developed exists Its specific application field has good performance.
The content of the invention
The present invention solves the technical problem of providing a kind of new two phase stainless steel, the plasticity of such steel, toughness are more Height, no brittleness at room temperature, intergranular corrosion resistance performance and welding performance are significantly increased, at the same the two phase stainless steel have it is excellent resistance to Pitting performance, and a kind of section nickel and stainless steel.
In order to solve the above technical problems, one aspect of the present invention is:A kind of new two phase stainless steel, it is special Sign is that it is mixed by martensitic stain less steel and ferritic stainless steel, and martensite is stainless in the new two phase stainless steel Steel and ferritic stainless steel mass ratio are 3:2.5, the martensitic stain less steel includes:Molybdenum rod element, manganese element, chromium, Described ferritic stainless steel includes:Carbon, ferro element, P elements, nickel element, each component in the martensitic stain less steel Mass fraction be:Molybdenum rod element 6-10 parts, manganese element 1-5 parts, chromium 0.5-3 parts are each in described ferritic stainless steel The mass fraction of component is:Carbon 5-15 parts, ferro element 2.5-8 parts, P elements 1.5-3 parts, nickel element 0.5-3 parts.
In a preferred embodiment of the present invention, martensitic stain less steel and ferrite be not in described new two phase stainless steel The steel quality ratio that becomes rusty is 2.5:3.5.
In a preferred embodiment of the present invention, the mass fraction of each component is in described martensitic stain less steel:Molybdenum rod 6 parts of element, 1 part of manganese element, 0.5 part of chromium.
In a preferred embodiment of the present invention, the mass fraction of each component is in described martensitic stain less steel:Molybdenum rod 8 parts of element, 3 parts of manganese element, 1.5 parts of chromium.
In a preferred embodiment of the present invention, the mass fraction of each component is in described ferritic stainless steel:Carbon member 10 parts of element, 5.5 parts of ferro element, 2.5 parts of P elements, 0.5 part of nickel element.
In a preferred embodiment of the present invention, the mass fraction of each component is in described ferritic stainless steel:Carbon member 15 parts of element, 8 parts of ferro element, 3 parts of P elements, 3 parts of nickel element.
The beneficial effects of the invention are as follows:New two phase stainless steel provided by the invention, plasticity, the toughness of such steel are higher, Without brittleness at room temperature, intergranular corrosion resistance performance and welding performance are significantly increased, while the two phase stainless steel has excellent resistance to hole Corrosion energy, and a kind of section nickel and stainless steel.
