- This patent application discloses compositions of austenitic stainless steels with a low nickel content and a relatively high manganese content having corrosion resistance equivalent to or greater than that of conventional commercial grades with a high nickel content, such as AISI 304, 301, 201, 202, after immersion tests in chlorinated medium and test in SO 2 . It is well specified the influence of copper, molybdenum and nickel, nickel having to be in low content, but the influence of elements such as calcium, boron, sulfur, is not approached.
- patent JP 54038217 deals with a steel Manganese austenitic with the following composition:: carbon: less than 0.04%; silicon: less than 1%; manganese: 6% -13%; nickel: 1.0% -3.5%; chromium: 13% -19%; niobium: less than 0.3%; copper: 1.0% -3.5%, earth rare: 0.005% -0.3%.
- the steel described has a resistance to corrosion. at least equivalent to that of stainless steel type AISI 304 and, a high resistance to intergranular corrosion. It is not about elements sulfur, calcium and boron or their influence on the different types of corrosion.
- patent JP 52024914 presents a steel austenitic, the composition of which is as follows: carbon: 0.11% -0.15%; silicon: less than 1%; manganese: 8.0% -11%; nickel: 1.0% -3.5%; chromium: 16% -18%; nitrogen: 0.05% -0.15%; copper: 0.5% -3.5%; molybdenum: less than 0.5%. It is taught that lower nickel content will not harm not corrosion. The influence of elements such as sulfur, boron is not not presented.
- the present invention aims to develop an austenitic steel with a very low nickel content which exhibits close corrosion resistance that of AISI 304 steel, in particular in the field of resistance to pitting, cavernous and generalized corrosion.
- the steel may also contain from 0.01% to 2% molybdenum.
- Figures 1 and 2 show the comparative values of the potential pitting, respectively in NaCI, 0.02M, pH 6.6 and 23 ° C and NaCI, 0.5M, pH 6.6 and 23 ° C, for different types of steels taken as reference and for three compositions according to the invention marked with an asterisk.
- FIG. 3 shows the evolution of the puncture potentials, in NaCI, 0.02M, pH 6.6 and 23 ° C, depending on the sulfur content for two reference steels and two steels according to the invention, one of which comprises in its composition a low chromium content.
- Figure 4 presents characteristics of resistance to corrosion cavernous in chlorinated medium for three steels taken as reference and three steels according to the invention and comprising in their composition different nickel contents.
- Figures 5 and 6 show the comparative values of the potential of sting respectively in NaCI, 0.02M, pH 6.6 and 23 ° C and in NaCI, 0.5M, pH 6.6 and 23 ° C for different types of steels allowing highlight the influence of boron.
- the steel according to the invention has been developed in order to meet the corrosion criteria and in particular the criteria for pitting corrosion, widespread and cavernous.
- Table 1 The chemical compositions of the steels tested are presented in Table 1, the first column giving casting references of tested steels, the steels according to the invention being marked with an asterisk.
- Table 2 presents the chemical compositions of the reference steels known and tested, for comparison.
- Tables 3 and 4 show the results of corrosion tests which justify the choice of the composition according to the invention.
- For pitting corrosion we give the potential E1 which corresponds to the probability of 1 pitting per cm 2 .
- For the cavernous corrosion the values of critical current densities i given in different NaCl solutions, 2M of variable pH are given.
- For the generalized corrosion the values of the critical current densities i are given in an acid solution H 2 SO 4 , 2M.
- the intergranular corrosion results are given in Table 4 in the form of mass losses ⁇ m and maximum crack depth in ⁇ m.
- Sulfur has no effect in terms of general corrosion resistance. In the field of cavernous corrosion, it slightly degrades the resistance to ignition and to the propagation of corrosion, with a higher critical current i at a pH greater than or equal to 2.0 when the sulfur content increases. On the other hand, in the area of pitting corrosion, its effect is much greater. By lowering the sulfur content to levels of the order of 10 10 -4 %, in the composition of steels containing in their composition little nickel, the resistance to initiation of the pitting is greatly improved.
- the steel according to the invention has the same properties as a reference steel AISI 304 or an AISI 430 Ti steel which comprises around 30 10 -4 % of sulfur, while low nickel steel, with a sulfur content of 30 10 -4 %, behaves like a reference steel AISI 430 Nb.
- nickel is very beneficial in the field of generalized corrosion and cavernous corrosion.
- a nickel content of less than 2% is preferable for good resistance to pitting corrosion.
- Figure 4 presents, in the form of curves giving the values activity currents as a function of the pH of a chlorinated solution, the cavernous corrosion behavior of various reference steels and steels according to the invention.
- the activity currents are proportional to the corrosion rate. The more the curve is located towards the abscissa, the lower the corrosion rates and therefore the better the corrosion resistance. The effect of copper.
- Copper has a beneficial effect in the field of corrosion widespread. To have a behavior equivalent to that of a steel of type AISI 304, it is shown by the behavior of steel 804 that a copper content of 2% can be considered insufficient, so that a copper content of 3% is better, as shown by the behavior of steel 801.
- Copper however, has a detrimental effect on resistance to corrosion by pitting, as shown in Figures 1 and 2 or Table 3.
- Steel 801 with a copper content of 3% has pitting potentials less than those of 804 steel with a copper content of 2%.
- the content of copper is according to the invention, preferably limited to 4%.
- the calcium content must be very low, i.e. less than 20.10 -4 % and preferably less than 10.10 -4 %.
- Chromium is beneficial in the field of corrosion generalized, pitting corrosion and cavernous corrosion as it appears in table 3 by comparing the values obtained on steels 584 and 723, 801 and 806. A minimum content of 15% is necessary to ensure good corrosion behavior, but a content of 16.5% is preferable to obtain corrosion resistance that meets a corrosion resistance comparable to that of a standard steel of the type AISI 304 or AISI 430 Ti.
- the steel according to the invention exhibits corrosion resistance comparable to that of AISI 304 reference steel but contains in its little nickel composition.
- the steel according to the invention has a much higher behavior. to that of steels of the type AISI 430 Ti in the field of corrosion widespread and cavernous.
