Description
Technical field
The present invention relates to a kind of stainless steel hot rolled steel plate.
Background technology
Stainless steel is a kind of special material, have the feature of functional materials and structured material concurrently, be widely used in industry and civilian various fields with the premium properties of the uniquenesses such as its stainless, anti-corrosion, heat-resisting, low temperature resistant, easy processing, recoverable, exquisite appearance, life cycle or cost are low.The whole world stainless steel amount of expending is also to increase year by year.
In stainless steel due to its excellent erosion resistance and anti-toughness and austenite stainless steel (austenitic stainless steel) SUS304 (18%Cr-8%Ni) (Japanese Industrial Standands, JIS G 4305) extensively is used.Although 304 stainless steels have good character, noble metal Ni content is up to 9%, thereby price is high.Along with the increase of stainless steel output, the nickel consumption also constantly increases in recent years, the more and more anxiety that nickel resources is become, and the nickel price sharp rises thereupon, and 304 stainless costs further increase.Affected by the nickel price increase, in order to reduce production costs, global enterprises of producing stainless steel is all at Devoting Major Efforts To Developing and development low nickel or without the stainless steel of nickel cheaply.
Austenitic stainless steel when containing Cr, Ni, C in steel, has stable austenite structure.Austenitic stainless steel is nonmagnetic and have high tenacity and plasticity.
Summary of the invention
The object of the present invention is to provide a kind of stainless steel hot rolled steel plate.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of stainless steel hot rolled steel plate is characterized in that, according to quality percentage composition meter, contain C:0.05-0.09%, below Si:1.00%, below Mn:2.00%, Cr:18.00-23.00%, Ni:4.50-10.50%, below N:0.20%, Mo:0-3.50% is below P:0.035%, below S:0.020%, all the other are Fe and inevitable impurity.
The present invention is according to quality percentage composition meter, C:0.005-0.019%, and below Si:0.75%, Cr:21.00-23.00%, Ni:4.50-6.50%, N:0.08-0.10% is below P:0.030%, below S:0.015%.
The present invention is according to quality percentage composition meter, also contains to be selected from the following or Ti:0.008% of Cu:0.5-1.0%, Co:1.0% with lower at least a.
Below, unless otherwise specified, the % of chemical composition all represents the meaning of quality percentage composition.
Beneficial effect of the present invention: hot-rolled stainless steel plate hardness of the present invention is low, handling ease, and ductility is good and have high tenacity and plasticity.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
At first, the reason of the composition restriction of system stainless steel hot-rolled steel sheet of the present invention is described.
Below C:0.030%
C easily forms the Cr carbide, if surpass 0.030%, forms the Cr carbide at heat affected zone when welding, and becomes the reason of grain boundary corrosion.Therefore, C is made as below 0.030%, is preferably below 0.015%.When further requiring high corrosion resistance, more preferably be made as below 0.010%.
Below Si:1.00%
If Si surpasses 1.00% make toughness drop, therefore, Si is made as below 1.00%.Be preferably below 0.50%.Should illustrate, because Si is as the useful element of reductor, so preferably be made as more than 0.05%.
Below Mn:2.00%
In steelmaking process, manganese is good reductor and sweetening agent, improves intensity, can replace the interpolation of Ni, but concerning the process of refining, adds too much Mn meeting Eroded furnace wall.
Cr：18.00-23.00%
For the main interpolation element of stainless steel, generally more than 12%, because generating Cr2O3 passive state protective membrane, be the reason of stainless steel tool solidity to corrosion maximum, the increase of Cr content, the stability of protective membrane also promotes relatively.Can high temperature oxidation resisting.
Ni：4.50-10.50%
Improve the intensity of steel, and keep good plasticity and toughness.Nickel has higher corrosion resistance to soda acid, at high temperature has antirust and temperature capacity.But because nickel is more rare resource, therefore should adopt other alloying elements to substitute steel nickel chrome as far as possible.
Below N:0.20%
Nitrogen can improve the intensity of steel, and low-temperature flexibility and weldability increase aging sensitivity.
Mo：0-3.50%
Increase Mo and can strengthen the passive state film, be conducive to anti-pitting, improve the resistivity to chlorion; Mo more than 2% can effectively improve the benefit that anti-sulfuric acid corrodes; Also increase on the other hand sclerosis energy 4, ferrite phase SF Stability Factor.
Below P:0.035%
In the ordinary course of things, phosphorus is harmful element in steel, increases the cold shortness of steel, and welding property is degenerated, and reduces plasticity, and cold-bending property is degenerated.Therefore require usually that in steel, phosphorus content is less than 0.045%, the high-quality steel requires some more low.
Below S:0.020%
Sulphur is also harmful element under normal conditions.Make steel produce red brittleness, reduce ductility and the toughness of steel, become crackle when rolling forging.Sulphur is also unfavorable to welding property, reduces erosion resistance.So usually require sulphur content less than 0.055%, the high-quality steel requires less than 0.040%.The sulphur that adds 0.08-0.20% in steel can improve machinability, usually claims free-cutting steel.
Stainless steel hot rolled steel plate of the present invention must obtain the purpose characteristic by element because of above-mentioned, but can also contain following element according to desirable characteristic.
Cu：0.5-1.0%
Cu is for the element that improves erosion resistance, particularly effective element aspect the reduction crevice corrosion.In order to bring into play this effect, be necessary for more than 0.3%.The Cu too high levels, hot workability reduces.Therefore, Cu is made as 0.5-1.0%.
Below Co:1.0%
Co is the element that helps to improve toughness.In order to obtain this effect, Co is preferably more than 0.05%.But, if surpass 1.0%, ductility is reduced.Therefore, Co is made as below 1.0%.
Ti：0.008%
Ti forms thick nitride, reduces toughness, therefore, Ti is made as below 0.015%, is preferably below 0.010%, further requires in the situation of high tenacity.More preferably be made as below 0.008%.
