Glömde nämna att materialet som jag har valt att använda är MA253.
Står lite om det på sandviks sida att läsa om. Jag klistrar in lite här.
Air
Sandvik 253 MA has very high resistance to oxidation, especially at cyclically varying temperatures. See Figs. 3 and 4. The service temperature in air should not exceed about 1150°C (2100°F).
Isothermal oxidation at 1150°C (2100°F) for 100 h results in a corrosion rate of about 0.3 mm/year (13 mpy), and exposure at the same temperature for 1000 h causes about 0.2 mm/year (9 mpy).
Cyclic oxidation at 1150°C (2100oF) for 5 x 24 h, with cooling to room temperature every 24 hours gives a corrosion rate of less than 1.1 mm/year (43 mpy), which is only marginally greater than the corrosion rate at 1000°C (1830°F).
Cyclic oxidation testing for 1000 h (15 minutes at the testing temperature and 5 minutes at room temperature, making a total of 3000 cycles) places heavy demands on the elasticity and adhesive capacity of the oxide. The test results in Fig. 4 show that the resistance of Sandvik 253 MA in such difficult conditions is superior to that of both ASTM TP310 and EN 1.4828 (ASTM TP309). The very good properties of this grade in cyclic conditions have been achieved by adding rare earth metals and silicon.
Figure 3. Oxidation in air during cyclic testing 5x24 h with cooling to room temperature every 24 h. Comparison of Sandvik 253 MA with four other high temperature materials.
1 = EN 1.4828 (ASTM TP309)
2 = ASTM TP446
3 = ASTM TP310
4 = Sandvik 253 MA
5 = Alloy 800 H
Med andra ord så kommer den inte att deformeras det minst lilla för mitt ändamål och kommer aldrig att brinna ut av värmen då temperaturen skall helst inte överstiga 600 till 650 grader inne i förkammare.
