Can we manufacture non-standard grades of Ductile iron ?
Yes, we can make non-standard grades of ductile iron. Our team at Castwise is well-equipped to understand customer requirements and adept at adjusting alloying and base materials to create non-standard grades.
Understanding Ductile Iron Grades
Ductile iron is typically classified into standard grades such as:
- 400-18: Known for its excellent elongation, often improved by annealing.
- 500-7: Offers a good balance of strength and ductility.
- 600-3: Known for higher strength with moderate ductility.
However, customer demands often necessitate either highly hard or highly ductile grades. We sometimes incorporate heat treatment when necessary. For instance, annealing in the 400-18 grade significantly enhances elongation.
Expertise at Castwise
Our metallurgist at Castwise boasts over 25 years of experience in the foundry industry and has been a part of our team for the past 18 years. His profound knowledge of alloying and additives in ductile iron, coupled with best practices, ensures that we achieve the desired results for our clients.
Case Study: Gauge Wheel Arm for John Deere USA
One notable example is our development of the gauge wheel arm, a tier 2 supply to John Deere USA. The drawing specified a grade of 600-3, with hardness ranging from 190 BHN to 270 BHN. The customer desired a hardness around 260 BHN. We mutually agreed to target a range of 250 - 280 BHN, but without the use of heat treatment post-casting. Our solution was to achieve this through specialized alloying, making it a regular product for us now.
