Gray iron material specifications
Gray cast iron is an iron, carbon, silicon, magnanese alloy. Cast iron is the most versatile of all metals foundry. It´s high porcentage of carbon makes easier foundry fusion and manufacture machinery.
The low grade or absence of contractions and a high facility of molding provides high foundry quality.
This grade of cast iron it´s an iron with a high resistance, modified to control hardness & microstructure.Get´s it´s maximun hardness as a result of refined control of the chemical composition, size and
graphite scams type. We obtained tension properties desired through the control of these elements and the adition of other alloy elements.
Gray cast iron is commonly used in general services and wet medias such as clean water, waste,oil, gas & steam
