Cast Iron Spherulitic Graphite Dossmann Eisengiesserei

23 行  Cast Iron Spherulitic Graphite. Spherulitic graphite offers qualities similar to steel, which are generated with a special metallurgic treatment. Thanks to the graphite contained in the spheres, chip interruption can be achieved, and the tool wear can be lowered despite relatively high strength. In this way, the cast iron spherulitic graphite

Spherulitic graphite cast iron Spherulitic graphite cast iron (EN-GJS) Spherulitic graphite cast iron, also known as nodular cast iron, is an iron-carbon-alloy with a high carbon share of up to four per cent. Accordingly, the structure of graphite has a big influence on the mechanic characteristics of the material.

1975-6-1  A typical spheroidal graphite cast iron. X100. (ii) that the spherulite is encased in a ring of face centered cubic iron (austenite) and grows by a process of carbon diffusion through this austenite ring. The austenite ring hypothesis was based mainly on observations of a ring of almost pure iron (ferrite) around spherulites as seen in Fig. 2.

What is spheroidal graphite cast iron? Willman

Spherical graphite iron castings (ductile iron castings) are very strong compared to regular cast iron (gray iron). The tensile strength of cast iron is 20,000 60,000 psi while ductile iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile iron is generally 40,000 90,000 psi but the yield strength of cast
