Definitions
- the present invention relates to an abrasion-resistant steel and its method of manufacture.
- Abrasion resistant steels are well known and are generally steels of high hardness (between 400 and 500 Brinell) having a martensitic structure, and containing from 0.12% to 0.3% carbon. It is generally accepted that in order to increase the wear resistance it is sufficient to increase the hardness, but this is done to the detriment of other properties such as the ability to weld or shape by folding, for example . Also, in order to obtain steels having both very good wear resistance and good processability, other means have been sought besides increasing the hardness.
- the object of the present invention is to overcome these disadvantages by providing an abrasion-resistant steel sheet having a good flatness and which, all things being equal, has an abrasion resistance better than that of steels. known.
- quenching may be followed by tempering at a temperature below 350 ° C, and preferably below 250 ° C.
- the invention also relates to a part, and in particular a sheet obtained in particular by this method, the steel having a structure consisting of 5% to 20% retained austenite, the remainder of the structure being martensitic or martensite-bainitic with carbides .
- the piece is a sheet, its thickness may be between 2 mm and 150 mm and its flatness may be characterized by an arrow less than or equal to 12 mm / m, and preferably less than 5 mm / m.
- the hardness is preferably between 280 HB and 450 HB.
- the hardness is preferably between 380 HB and 550 HB.
- the hardness is preferably between 450 HB and 650 HB.
- the carbon, titanium, zirconium and nitrogen contents must be such that: 0 , 1 % ⁇ VS - Ti / 4 - Zr / 8 + 7 ⁇ NOT / 8 ⁇ 0 , 55 %
- C * represents the free carbon content after precipitation of the titanium and zirconium carbides, taking into account the formation of titanium and zirconium nitrides.
- This free carbon content C * must be greater than 0.1%, and preferably greater than or equal to 0.22%, to have a martensite having a minimum hardness, but beyond 0.55% the toughness and the the processability are too deteriorated.
- the chemical composition must be chosen so that the quenchability of the steel is sufficient, given the thickness of the sheet that is to be manufactured.
- the silicon content is greater than 0.5% so as to promote the formation of retained austenite.
- the contents of Ti, Zr and N should preferably be such that: Ti + Zr / 2 - 7xN / 2 ⁇ 0.05%, and more preferably greater than 0.1%, and more preferably, greater than 0.3% for the carbide content to be sufficient.
- the micrographic structure of the steel consists of martensite or bainite or a mixture of these two structures, and from 5% to 20% retained austenite.
- This structure further comprising large titanium or zirconium carbides, or even carbides of niobium, tantalum or vanadium, formed at high temperature.
- the inventors have found that the effectiveness of large carbides for the improvement of the abrasion resistance could be obelated by premature loosening thereof and that this loosening could be avoided by the presence of metastable austenite which is transformed in fresh martensite under the effect of abrasion phenomena.
- the conversion of the metastable austenite to fresh martensite is by swelling, this transformation in the abraded underlayer increases the resistance to carburetion and thus improves the abrasion resistance.
- the steel is made, it flows in the form of slab or ingot.
- the slab or slug is hot-rolled to obtain a sheet which is subjected to a heat treatment which makes it possible at the same time to obtain the desired structure and a good flatness without subsequent planing or with limited planing.
- the heat treatment can be carried out directly in the hot rolling or carried out later, possibly after a cold planing or half-hot.
- an expansion treatment can be carried out at a temperature of less than or equal to 350 ° C, and preferably less than or equal to 250 ° C.
- the hardness being a function of the free carbon content C * the same hardness can be obtained with very different titanium or zirconium contents. With equal hardness, the resistance to abrasion is all the higher as the titanium or zirconium content is important. Similarly, titanium content or equal zirconium, the resistance to abrasion is even better than the hardness is high. In addition, the implementation of the steel is all the easier as the free carbon content is low, but with equal free carbon content, ductility is even better than the titanium content is low. All of these considerations make it possible to choose the carbon and titanium or zirconium contents which lead to all of the properties best suited to each field of application.
- steel sheets identified A to G according to the invention and H to J according to the prior art are considered.
- the chemical compositions of the steels, expressed in 10 -3 % by weight, as well as the hardness, the residual austenite content of the structure and a wear resistance index Rus, are reported in Table 1.
- the wear resistance index Rus varies as the logarithm of the inverse of the weight loss of a prismatic specimen rotated in a tank containing calibrated quartzite granules.
- All the sheets have a thickness of 30 mm, and the sheets corresponding to the steels A to G have been quenched according to the invention, after austenitization at 900 ° C.
- the sheets according to the invention have a martensite-bainitic structure containing from 5% to 20% retained austenite, whereas the sheets given for comparison have a completely martensitic structure, that is to say, martensitic and not containing more than 2 or 3% retained austenite. All plates contain carbides.
- the pair of steels F, G (according to the invention) is clearly different from the pair of steels I, J, term of gain of holding brought by the titanium.
- the resistance gain Rus supplied by 0.245% of Ti is 0.46, whereas it is only 0.31 for a difference of 0.265% of Ti in the case of the pair I, J. .
- the deformation after cooling, without planing, for the steel sheets according to the invention is less than 10 mm / m, and is about 15 mm / m for the steel sheet H.
