Ductile iron is what?(of)
If you want to for chemical analysis of nodular cast iron, this is
what you will usually find:
Iron ~ 94%
Carbon 3.2 -3.60%
Silicon 2.2 -2.8%
Manganese 0.1- 0.2%
Magnesium 0.03- 0.04%
P 0.005- 0.04%
Sulfur 0.005- 0.02%
Copper < = 0.40%
In order to improve the strength of the nodular cast iron, can add
additional tin or copper.In order to improve the corrosion
resistance, copper, nickel and chromium alternative to 15-30% of
iron.
Common level of nodular cast iron:
Although there are many different nodular cast iron specifications,
foundry usually provide three kinds of common brand;
| Physical and Mechanical Properties | ASTM A536, Grade 60-40-18 | ASTM A536, Grade 65-45-12 | ASTM A536, Grade 80-55-06 |
| Tensile Strength, min, psi | 60000 | 65000 | 80000 |
| Tensile Strength, min, MPa | 414 | 448 | 552 |
| Yield Strength, min, psi | 40000 | 45000 | 55000 |
| Yield Strength, min, MPa | 276 | 310 | 379 |
| Elongation in 2 in. or 50 mm, min % | 18 | 12 | 6 |
| Density lb/in3 | 0.256 | 0.256 | 0.256 |
| Density g/cm3 | 7.1 | 7.1 | 7.1 |
| Melting Temperature (Degrees F) | 2,100 - 2,190 | 2,100 - 2,190 | 2,100 - 2,190 |
| Melting Temperature (Degrees C) | 1,150 - 1,200 | 1,150 - 1,200 | 1,150 - 1,200 |
| Compressive Strength Ksi | 429 | 429 | 429 |
| Compressive Strength MPa | 2960 | 2960 | 2960 |
| UNS | F32800 | F33100 | F33800 |
Ductile iron castings:
Nodular cast iron was invented by the middle of the twentieth
century synthesis of metal material, is a kind of used in the
manufacture of cast iron.Cast iron technology of molten iron and
metal material, has the ductility.
Ductile iron process must start from the production of ductile
iron, nodular cast iron is formed by adding small amounts of other
elements into the iron, so that the carbon ball instead of thin
sheet.This enables the material to without destroying situation to
change.Usually, nodular cast iron has a higher tensile strength
than that of gray cast iron, grey cast iron is traditionally used
in the manufacture of iron cast iron products.Nodular cast iron, as
the name implies, than the traditional more malleable iron
material, the traditional iron materials tend to be more brittle,
easy to fracture under high tensile stress.Ductile iron is usually
used in the manufacture of cast iron pipe, the use of the water and
sewer.Nodular cast iron used in many various applications in
different industries.These industries include, but are not limited
to agriculture, automobile, irrigation, ventilation, hydraulic
pressure.
We can provide:
Material: alloy steel, carbon steel, stainless steel, malleable
cast iron, grey cast iron, ductile iron, aluminum bronze, etc
Process: precision casting, sand casting, resin sand casting, green
sand casting), permanent casting, die casting, centrifugal casting,
forging, stamping and so on.
