About ADI

AUSTEMPERED DUCTILE IRON - ADI

           Austempering is an isothermal heat treatment process which significantly improves both the strength and wear resistance of ductile iron whilst retaining the impact resistance and ductility for which the material is noted.

           ADI is characterized by its spheroidal graphite nodules spaced within the matrix. These nodules reduce micro segregation of solutes within the material. For ADI, the material has been Austempered such that the matrix is transformed into ausferrite, or a mixture of acicular ferrite and austenite. The microstructure is used to classify ADI into grades, which depend on the heat treatment process and not the composition of the material.

A.D.I. is a proven cost-effective alternative to cast and forged steel and offers the following advantages

ADI Heat Treatment.

TECHNO RINGS – Your one-stop solution for Casting, Machining and Heat Treatment Services, Induction Hardening and ADI Heat Treatment.

Weight Saving:

A.D.I. is 10% lighter than steel. Higher strength allows smaller sections than conventional SG castings, whilst retaining performance criteria.

Machining:

Nearness to net shape reduces machining costs.

Tooling:

Tooling is less expensive with improved lead time when compared to forging dies.

Environment:

The amount of energy required to produce A.D.I. can be upto 50% less than steel casting and forging counterparts.

Piece Price:

As a conversion from steel castings, forgings and fabrications, A.D.I. 

can very often offer worthwhile cost savings.
