Description

A kind of new metallic material

Invention field

The present invention relates to a kind of making method of metallic substance, belong to machinery and wait metallic substance applied technical field.

Background technology

It is more extensive that current metallic substance interalloy metallic substance uses, and is elementary composition by C, Si, Fe etc. in general metallic substance substantially.These metallic substance can meet general industry demand, but at some for the performance requriements of metallic substance compared with high field, conventional metallic substance also cannot 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, is penetrated into the performance that can be good at improving iron and steel in iron and steel, and therefore, the research of rare earth aspect metallurgical industry at present starts more deep.But rare earth element price general charged is more expensive, the amount that it adds and with those combination of components all or the further target of research of needs.

Summary of the invention

The present invention solves the problem existing at present, aims to provide a kind of new metallic material.

For realizing above technical purpose, the present invention realizes by the following technical solutions: a kind of new metallic material, and making raw material is:

C Si Mn Ni Cr Cu Al Ti Sn and Fe and rare elements; Wherein each integral part percentage is:

C: 0.2-2.4%, Si:0.3-1.3%, Mn:0.9-2.0%, Ni: 1.0-10%, Cr: 15-25%, Cu: 0.8-2.3%, Al:0.1-1.0%, Ti:0.1-0.8%, Sn:0.8%-1.5%; At least one in Ce, La in rare earth element: 0.6-1.7%, all the other are Fe.

In the present invention

Ni can improve fastness to wear and the toughness of metallic substance;

Mn can carry material toughness, intensity, hardness and wear resistance,, hardening capacity, improve the hot workability of metallic substance;

Ni can improve plasticity-, weldability and the toughness of metallic substance;

Cr can improve intensity, hardness and the wear resistance of metallic substance;

Cu can strengthen the toughness of metallic substance, working pressure can also reduce forming process time simultaneously, and less expensive;

Al can alleviate the weight of metallic substance, and increases hardness and intensity;

Ti can play the cast structure of fining metal material and the effect of seam organization;

Although do not add S, P in the present invention, but in starting material, also can bring S, P into, these two kinds of elements belong to objectionable impurities, and rare earth metal is due to its high activity, can slough the objectionable impurities such as S, P in molten metal, play the effect of purifying molten metal, control sulfide and other compound forms, play rotten, crystal grain thinning and strengthening effect, can also improve significantly toughness, wear resistance, the erosion resistance of metallic substance simultaneously, and can also improve Weldability and the low-temperature performance of metallic substance, therefore in the present invention, add appropriate rare earth element.
