In-Depth Resources on Ductile Iron and Advanced Castings

Willman Industries provides technical papers and resources for engineers, designers, and manufacturers looking to understand better ductile iron, solution-strengthened ductile iron, and Austempered Ductile Iron (ADI). These resources highlight the unique properties, engineering specifications, and performance benefits of different iron types produced in our ISO 9001:2015 certified foundry.

Ductile Iron

Ductile iron is one of the most widely used cast iron types in industrial applications. Willman Industries offers new generation ductile iron grades that provide:

• Higher strength and durability
• Greater elongation and flexibility

Uniform casting properties

These grades can be produced as cast, allowing for improved performance in structural and mechanical components.

Solution-Strengthened Ductile Iron

Our solution-strengthened ductile iron (SSD or SSDI) grades offer enhanced mechanical properties:

• High strength combined with high elongation
• Ideal for heavy-duty industrial and structural applications
• Produced using proprietary processes to ensure consistency and reliability

Austempered Ductile Iron (ADI)

Austempered Ductile Iron (ADI) is a heat-treated ductile iron that provides exceptional wear resistance, toughness, and fatigue performance.

• ADI is produced via interrupted quench heat treatment, usually into a salt bath
• Suitable for high-stress components in construction, mining, automotive, and industrial machinery
