Definitions
- the invention relates to ferritic cast iron comprising spheroidal graphite, containing, in % by mass:
- the accompanying elements which occur most frequently in ferritic cast iron and usually originate from the starting materials used are, for example, phosphorus (P), magnesium (Mg), chromium (Cr), nickel (Ni), molybdenum (Mo), copper (Cu), aluminum (Al), titanium (Ti), vanadium (V), niobium (Nb), zirconium (Zr), antimony (Sb), tin (Sn), lead (Pb), cerium (Ce), bismuth (Bi), tellurium (Te) and also further rare earths and the like.
- Some of these accompanying elements can, particularly if they are carbide formers, adversely affect the microstructure being formed. For this reason, the total content of accompanying elements is generally limited to the value indicated above in the case of commercial ferritic cast iron comprising spheroidal graphite.
- the standard DIN-EN 1535 relevant to ferritic cast iron comprising spheroidal graphite leaves the chemical composition in detail and thus also the content of accompanying elements up to the producer, as long as the physical properties sent forth in the standard are adhered to.
- Ferritic cast iron comprising spheroidal graphite is basically an iron material which has a microstructure having embedded spheroidal graphite.
- This particular microstructure results in advantageous properties, including, in particular, a relatively high tensile strength of 320-400 N/mm 2 at an elongation of from 12 to 22% and also a high notched impact energy of 10 to 12 J at temperatures of from ⁇ 20° C. to ⁇ 40° C. (cf., for example, GJS-400-18-LT or GJS-350-22-LT in accordance with the standard DIN-EN-1563:2011).
- This relatively inexpensive material which can be produced with great process reliability also displays a high deformability before failure, a high resistance to cracks and a high crack arresting capability. For this reason, this material is particularly suitable for applications in which the components are subjected to frequent cyclic collective loads, including at low temperature.
- the invention proceeding from a ferritic cast iron comprising spheroidal graphite of the type mentioned at the outset proposes that the accompanying elements chromium, vanadium, niobium and titanium in total be limited to 0.05% by mass.
- Ferritic cast iron comprising spheroidal graphite and having the following composition:
- Ferritic cast iron comprising spheroidal graphite and having the following composition:
- Ferritic cast iron comprising spheroidal graphite and having the following composition:
