Definitions
- the invention relates to ferritic spheroidal graphite cast iron, contained in mass%:
- ferritic cast iron accompanying elements which mostly come from the starting materials used (scrap and / or pig iron and / or circulating material), for example, phosphorus (P), magnesium (Mg), chromium (Cr), nickel (Ni), Molybdenum (Mo), copper (Cu), aluminum (AI), titanium (Ti), vanadium (V), niobium (Nb), zirconium (Zr), antimony (Sb), tin (Sn), lead (Pb), Cerium (Ce), bismuth (Bi), tellurium (Te) and other rare earths dergl.
- P phosphorus
- Mg magnesium
- Cr chromium
- Ni nickel
- Cu copper
- aluminum (AI) titanium
- Ti vanadium
- Nb niobium
- Zr zirconium
- antimony Sb
- lead (Pb) Cerium (Ce), bismuth (Bi), tellurium (
- ferritic spheroidal graphite cast iron is an iron material that has a structure with interspersed spherical graphite.
- This special microstructure results in advantageous properties, in particular a relatively high tensile strength of 320-400 N / mm 2 at an elongation of 12 to 22% and a high impact energy of 10 to 12J at temperatures from -20 ° C to -40 ° C (compare eg GJS-400-18-LT or GJS-350-22-LT according to the standard DIN-EN-1563: 201 1).
- This relatively inexpensive material which can be produced with high process reliability is also distinguished by its high deformability before failure, by a high resistance to cracking and by a high crack absorption capacity.
- the invention proposes, starting from a ferritic spheroidal graphite cast iron of the type mentioned that the accompanying elements chromium, vanadium, niobium and titanium are limited to a total of 0.05 mass%.
