Ductile and Gray Cast Iron Price per Ton

Many cast iron buyers are familiar to evaluate ductile iron and gray iron casting prices by USD/ton. This evaluation is not suitable for those iron castings with machining works, but this method could be used for evaluating the prices of rough castings, and some cast iron parts with simple machining requirements.

Ductile Iron Price per Ton

For rough ductile iron casting parts: 1300 – 1600 USD/ton

Gray Iron Price per Ton

For rough gray iron casting parts: 1450 – 1750 USD/ton

These are ex-work prices in China, so excluding the costs for packing, painting and delivery costs.

The prices changed in the range according to the different size, unit weights, structural complexity and production processes.

These price ranges are based on the common ductile iron material grades in ASTM A536 60-40-18, 60-42-10, 65-45-12, 70-50-05, 80-55-06, 80-60-03, and gray iron grades in ASTM A48 No. 20, No. 25, No.30, No. 35. As for the higher grades, their cast iron prices will be higher than these range, because of the more difficult for production, more alloy materials and extra heat treatment processes.

If the cast iron parts are very light, very small, very complex, or have very high requirements, then their prices per ton will be much higher than this range.

The casting processes also affects these prices, for example, the shell molding process more expensive than resin sand casting process, which is higher than green sand casting process.

According to experience of our Dandong Foundry, the price per ton could be used to evaluate the following cast iron products, such as manhole covers, counter weights, cast iron plates, balance weights, fishing sinkers, heavy base parts etc.
