Ausferritic Ductile Iron Technical Sheet

Ausferritic Ductile Iron

Durham Foundry manufactures ausferritic spheroidal graphite iron, or ADI, to BS ISO 17804. Within this standard are a range of grades which can be certified by ultimate tensile strength and 0.2% proof stress in N/mm2 and percentage elongation. There is no chemical data in the standard. Chemical analyses can be supplied but they would be for information only. If castings are ordered with a test certificate, a mechanical test is all that would be normally supplied unless the chemical analysis is specifically requested. The following table shows the grades that we supply as standard.

Ductile Cast Iron Technical Sheet

Ductile Cast Iron

Durham Foundry manufactures ductile iron to ISO 1083. Within this standard are a range of grades which can be certified by ultimate tensile strength and 0.2% proof stress in N/mm2 and percentage elongation.

This ductility results in excellent properties in tension as well as compression when compared to grey cast iron. There is no chemical data in the standard. Chemical analyses can be supplied but they would be for information only. If castings are ordered with a test certificate, a tensile test is all that would be normally supplied unless the chemical analysis is specifically requested. The following table shows the grades that we supply as standard.

Wear Resistant Chrome Iron Technical Sheet

Wear Resistant Chrome Iron

Durham Foundry manufactures abrasion resistant cast iron, often referred to as Ni Hard, to BS ISO 21988. Within this standard are a range of grades which can be certified by Brinell Hardness (HBW). All grades have a required chemical analysis and most grades can be supplied either as cast or heat treated. Although there are thirteen grades in the standard, all of which can be supplied, there are two grades that we manufacture on a regular basis.
