APPLICATION
SAW 304 is a highly effective inoculation alloy based on ferrosilicon and is espe cially suitable far casi iron with nodular graphite. The combination of Al and Bi greatly increases the number of spheres, in conjunction with Ce. The content of rare earth metals is precisely coordinated to the composition in arder to counteract graphite degeneration. The diffusion paths far carbon are reduced by increasing the number of spheres, which allows increased ferrite contents to be achieved in the cast state.
REFERENCE ANALYSIS
| % Si | 70 – 75 |
| % Al | 3,5 – 4,5 |
| % Ca | < 1,5 |
| % Bi | 0,5 – 0,8 |
| % Se | 0,5 – 0,8 |
| % Fe | residual |
ADDITION RATE
Corresponding to the relevan! conditions, i.e. base iron, inoculation method, cast parts to be cast, etc., the following added amounts
- Cast steel inoculation approx. 0.05 – 0.1%
- Ladle inoculation approx. 0.2 – 0.3%
are recommended.
SIZING
- 0,124 – 0,7 mm* (in-stream inoculation)
- 0,2 – 2 mm (ladle inoculation)
- 2 – 6 mm (ladle inoculation)
* In this grain size the Si content is somewhat below the value indicated above.
