Abstract

The invention provides super ferrite copper-containing anti-bacterial stainless steel. The super ferrite copper-containing anti-bacterial stainless steel comprises, by weight, 0.005-0.015% of C, 0.1-0.5% of Si, 0.1-0.5% of Mn, 25-28% of Cr, 1-3% of Ni, 3-5% of Mo, 0.005-0.015% of N, 0.1-0.5% of Nb, 0.1-0.5% of Ti, 0.5-1% of Cu and the balance Fe. The super ferrite copper-containing anti-bacterial stainless steel has the technical effects of maintaining the advantages of high strength, good oxidation resistance and excellent stress corrosion resistance of common ferrite stainless steel and overcoming the shortcomings of ductility and brittleness transition, sensitivity to intergranular corrosion and low toughness of the as-welded condition of the common ferrite stainless; 0.5-1% of Cu is added into the stainless steel, the special heat treatment is adopted, and therefore Cu educts can be uniformly dispersed in the stainless steel from outside to inside, and the antibacterial effect can be realized.

Description

A kind of super ferrite copper-bearing antibacterial rustless steel
Technical field
The present invention relates to a kind of super ferrite copper-bearing antibacterial rustless steel, belong to rustless steel technical field.
Background technology
Rustless steel is as important material a kind of in modern industry, the history of existing more than 100 year.Because rustless steel has high intensity, weldability, corrosion resistance, workability and surface, there are many excellent characteristics such as glossiness, in terms of the industry such as aerospace, chemical industry, automobile, food machinery, medicine, instrument and meter, the energy and building decoration, obtain extensive and important application.But along with developing rapidly of petrochemical industry, war industry and ocean development, rustless steel is had higher requirement, traditional rustless steel is not already adapted to the use requirement in special industry and specific function field, therefore, stainless steel material also develops to functional and particularity direction, occurs in that super stainless steel and meets the functional rustless steel that various specific function requires.
Current functional rustless steel function singleness, it is impossible to meet the demand in market.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of super ferrite copper-bearing antibacterial rustless steel.
The super ferrite copper-bearing antibacterial rustless steel of the present invention, according to percetage by weight, including following composition: C 0.005-0.015%, Si 0.1-0.5%, Mn 0.1-0.5%, Cr 25-28%, Ni 1-3%, Mo 3-5%, N 0.005-0.015%, Nb 0.1-0.5%, Ti 0.1-0.5%, Cu 0.5-1%, Fe surplus.
Preferably,
The super ferrite copper-bearing antibacterial rustless steel of the present invention, according to percetage by weight, including following composition: C 0.01%, Si 0.25%, Mn 0.25%, Cr 26%, Ni 2%, Mo 4%, N 0.01%, Nb 0.3%, Ti 0.3%, Cu 0.8%, Fe surplus.
The super ferrite copper-bearing antibacterial rustless steel of the present invention, have the following technical effect that super ferrite anti-bacteria stainless steel inherits the features such as common ferrite stainless hardness of steel height, good in oxidation resistance, stress corrosion resistant be excellent, improve the ductility of ferritic stainless steel simultaneously The limitation such as Transition of Brittleness, the low toughness more sensitive and as-welded to intercrystalline corrosion.In rustless steel, add the Cu of 0.5%～1% simultaneously, and take special thermal treatment, make rustless steel from surface to inner homogeneous disperse Cu precipitate, play antibacterial action.
