To learn more about our near net-shaped ductile iron investment casting processes for metal parts contact Aero Metals, or send us your project requirements today. Contact Aero Metals for a Ductile Iron Investment Casting Quote Today For Grade 4 and 5, it is recommended the austempering process for ductile iron castings be performed prior to any secondary straightening or machining. For Grades 1 -3, secondary machining operations can be performed prior to austempering in most cases. As-cast ductile iron can be austempered to achieve greater tensile and yield strengths as a secondary service.Īustempering is produced in five (5) different ASTM A897 grades with Grade 1 producing a tensile strength of 130 ksi and a yield of 90 ksi, up to a Grade 5 resulting in a tensile strength of 230 ksi and a yield of 185 ksi.

Nominal machining speed of 66 m/mm with carbide toolsĪustempered Ductile Iron Investment CastingĪustempering is a heat treat process developed to improve the strength and toughness of ferrous alloys like ductile iron.

Ductility (elongation) is limited to 3%.

High strength alloy with 100 ksi ultimate.

Nominal machining speed of 100 m/mm with carbide tools.Additionally, ductile irons are widely used in numerous industries including:Īero Metals provides many different near net shape ductile iron investment casting grades for your project requirement needs, some of which include: Ductile iron castings have many “best in class” characteristics, while also benefiting from being a cost-effective alternative to other ferrous alloys.

Prevent the formation of external shrinkageĭuctile Iron Investment Casting Applicationsĭuctile iron offers design flexibility and reduced manufacturing costs versus welded fabrications and forgings.

Additionally, net shape ductile iron gives the design engineer more design freedom and provides the best overall combination of cast and post-cast characteristics. This is all accomplished while maintaining a favorable cost of manufacturing. Near net shape ductile iron investment castings provide the design engineer with the best combination of part design, surface hardening ability, elasticity modulus, corrosion resistance, and strength versus weight ratio.
