ASTM A356 Ductile Iron Nodular Graphite Cast Iron Auto Parts Green Sand Casting Process

ASTM A356 Ductile Iron Nodular Graphite Cast Iron Auto Parts Green Sand Casting Process


Product Description and Process


ASTM A356 Ductile Iron Casting Process Cast Iron Foundry Auto Parts Supplier


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


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

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


Product Material and Uses


Normally produce with gray iron HT200, HT250, ductile iron 65-45-12, 60-40-18, 80-55-06, 80-60-03, 100-70-03, etc.

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.


Ductile iron castings have many advantages


Ductile iron – also referred to as spheroidal or nodular iron – is actually a group of irons that exhibit high strength, flexibility, durability and elasticity due to their unique microstructure. Cast ductile iron normally contains over 3 percent carbon; it can be bent, twisted or deformed without fracturing. Its mechanical properties are similar to steel, and far exceed those of standard cast irons.


Ductile iron castings are solid metal objects that result from molten ductile iron being poured into voids in a mold. The ductile iron subsequently cools and solidifies in the shape of the void it occupies.



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;
