Abstract
What the present invention relates to is a kind of austenite nonmagnetic stainless steel, and its chemical ingredients is:＜0.12%C,＜1.0%Si, 10～13%Mn,＜0.03%P,＜0.03%S, 12～14%Cr, 4～6%Ni, 1.5～2.5%Cu,＜0.02%Re, all the other are Fe, the preferential selection:＜0.06～0.1%C,＜1.0%Si, 10～11%Mn,＜0.03%P,＜0.03%S, 12-13%Cr, 4-5%Ni, 1.8-2.2%Cu ,≤0.02%Re, all the other are Fe.
This stainless steel is compared with the high chromium-nickel austenitic stainless steel of existing 18-8 type, have cheap, the processing good welding performance, technology is simple, and is anticorrosive, resistance of oxidation is strong, advantages such as no magnetic.
It can be made into various metal productss and component, and it is the ideal material of Industrial products.
Description
What the present invention relates to is a kind of austenite nonmagnetic stainless steel with high corrosion resistance energy.
The existing austenite non-magnetic rustproof steel capital is high nickel chromium stainless steel, and its shortcoming is to cost an arm and a leg, and poor processability is difficult to be shaped.
The objective of the invention is to make a kind of cheap, good processability, technology is simple, anticorrosive, resistance of oxidation is strong Cr-Ni-Mn-Cu is an alloy.
The invention provides a kind of 1Cr12Ni4Mn10Cu2Re austenitic stainless steel, its Chemical Composition is:＜0.12%C, and＜1.0%Si, 10～13%Mn,＜0.03%P,＜0.03%S, 12～14%Cr, 4～6%Ni, 1.5～2.5%Cu,＜0.02%Re, all the other are Fe,
The preferential selection:＜0.06～0.1%C,＜1.0%Si, 10～11%Mn,＜0.03%P,＜0.03%S, 12-13%Cr, 4-5%Ni, 1.8-2.2%Cu ,≤0.02%Re, all the other are Fe.
The present invention compares with chromium-nickel austenitic stainless steel commonly used (18-8 type), has the following advantages:
1, has stronger erosion resistance, the anticorrosive 18-8 type steel nickel chrome that is better than in acid, alkali, salt;
2, have various preferably comprehensive mechanical performances, austenite structure is stable;
3, have good casting, forge, roll, processing characteristics and weldability such as pressure, deep-draw.
4, this alloy good toughness, unit elongation is greater than 46%, and relative reduction in area is greater than 60%;
5, starting material can adopt ordinary scrap steel, in, low carbon ferromanganese, middle and high carbon ferrochrome, the source is sufficient, cheap, its cost only is 1/2nd of a 18-8 type steel nickel chrome.
Even 6 carry out deep processing, can not produce magnetic yet.
Embodiments of the invention:
The present invention is a raw material with steel scrap, low carbon ferromanganese, medium carbon ferrochrome, metallic nickel, metallic copper and mishmetal, becomes ingot casting by smelting and pouring in medium-frequency induction furnace or the electric arc furnace, and fully deoxidation, slagging-off in the melting require to carry out esr when high to material.
Example one, alloy ingredient: 0.061%C, 12.93%Cr, 4.86%Ni, 9.84%Mn, 2.10%Cu, 0.26%Si, 0.008%S, 0.019%P, 0.012%Re, all the other are Fe.Ingot casting is rolled into Φ 10mm wire rod, makes wire rod, silk material through operations such as solution treatment, wire drawings.Be used for high-grade bicycle spoke, motor bike spoke and standardized component, spring.
Example two, alloy ingredient: 0.05%C, 12.33%Cr, 4.38%Ni, 9.85%Mn, 2.07%Cu, 0.285%Si, 0.006%S, 0.019%P, 0.008%Re, all the other are Fe.Ingot casting is rolled into the wide 100mm steel plate of thickness 6mm, makes sheet material, band through solution treatment, operation such as cold rolling, is used for bicycle rim, splash pan, kitchen utensils, furniture and decorates.
More than two examples through comprehensively Performance Detection and tracking test, all conform with related standard requirements.
