SG Cast Iron Material 60-40-18 Ferritic Ductile Iron Casting ASTM A395 Casting Foundry

 

Product Description and Process

 

1. SG Cast Iron Material 60-40-18 Ferritic Ductile Iron Casting ASTM A395 Casting Foundry

 

2. Production process: green sand molding, pre-coated sand molding and resin sand molding which can produce iron castings from 50 gram to 2000 kilograms

 

3. Machining process: CNC machine, machining center, lathe, mill machine, drill machine, etc.

 

4. Surface treatment process: paint coating, electrophoretic coating, electrogalvanizing coating, black oxide coating, phosphate coating, powder coating, etc.

 

Product Material and Uses

 

1. Normally produce with gray iron HT200, HT250, ductile iron 65-45-12, 60-40-18, 80-55-06, 80-60-03, etc.

2. The ductile iron casting products are widely used for Auto-cars, trains, trucks, vehicle components, mining machinery components, agricultural machinery parts, textile machinery parts, construction machinery parts, etc.

 

Advantages of Ductile Iron

There are several advantages that ductile iron provides designers:

1. Ductile iron can be easily cast and machined.

2. It has an excellent strength to weight ratio.

3. Ductile iron can be made for a much lower cost than steel.

4. It has superior castability and machinability.

5. Ductile iron provides a designer with an exceptional combination of toughness, low cost manufacturing, and reliability.

 

Properties of Ductile Iron

To create different grades of ductile iron, one must control the matrix structure around the graphite during the casting process or through subsequent heat treatment. The minor compositional differences between the different grades of ductile iron exist in order to create the desired matrix (microstructures).

Ductile iron can be considered as steel with graphite spheroids dispersed throughout its matrix. The qualities of the metallic matrix in which the graphite spheroids are suspended have a significant effect on ductile iron’s properties, but the graphite spheroids themselves do not.

 

There are several matrices found within ductile iron, the most common being;

  1. Ferrite – a pure, ductile, flexible iron with little strength. This matrix has poor wear resistance, but high impact resistance and good machinability.
  2. Pearlite – a mechanical mixture of ferrite and iron carbide (Fe3C). It is relatively hard, with moderate ductility. It has high strength, good wear resistance, moderate impact resistance, and good machinability.
  3. Pearlite/Ferrite – a structure consisting of a mixture pearlite and ferrite, and the most common matrix for commercial grades of ductile iron.

 

ASTM A536 Standard for Ductile Iron Castings

 

ASTM A536 is the American standard specification for ductile iron castings, the main material grades including:

 

Grade 60-40-18
Grade 60-42-10
Grade 65-45-12
Grade 70-50-05
Grade 80-55-06
Grade 80-60-03
Grade 100-70-03
Grade 120-90-02

 

 

What is in Ductile Iron? (Composition)

If you were to do a chemical analysis of ductile iron, this is what you would normally find:

Iron ~94%

Carbon 3.2 – 3.60%

Silicon 2.2 – 2.8%

Manganese 0.1 – 0.2%

Magnesium 0.03 – 0.04%

Phosphorus 0.005 – 0.04%

Sulfur 0.005 – 0.02%

Copper <= 0.40%

To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.

 

 

 

Common Ductile Iron Grades

 

While there are many different ductile iron specifications, foundries routinely offer 3 common grades;
