What is High Silicon Cast Iron?
- High Silicon Cast Iron (HSCI) is an Iron alloy containing approximately 15% Silicon as the primary alloying element. Chromium is added to improve performance.
- Typical Standards are ASTM A518 and BS 1591. HSCI is primarily used in severe corrosive environments.
- Impressed cathodic protection anodes operate in severe conditions, often deep in the earth, where high silicon cast iron has proven to be dependable and economical.
- Anotec's proprietary "Chill Casting Process" was developed for superior corrosion resistance and impact strength. Generic HSCI is by nature a very brittle material with relatively low resistance to breaking. But Anotec Chill Cast HSCI is not fragile compared to centrifugally cast or sand cast anodes. This superior Chill Cast structure prolongs the working life of groundbeds by 10 to 20% over generic high silicon iron anodes.
