AS 1830 for Grey Cast Iron
AS 1830 is an Australia standard for
materials of
grey cast iron.
It is useful for iron casting buyers and suppliers. However, this
standard is not as common as ISO and ASTM standards, so we listed
some main information of this standard as followings, and provided
the cross-references with other popular standards. Hope this could
be useful for those
iron foundries
in China, such as our Dandong Foundry.
This standard is originated as AS B26 - 1942 and AS B89 - 1942.
Previous edition is AS 1830 - 2002. The fourth edition is published
in 2007.
This Standard was prepared by the Joint Standards
Australia/Standards New Zealand Committee MT-001, Iron and Steel, to
supersede AS 1830 - 2002, Grey cast iron.

Grey flake cast
irons are the most used of the general purpose engineering irons.
They are relatively inexpensive and easy to produce. They are
readily machined and the machined surfaces are resistant to sliding
wear.
They have high
thermal conductivity, low modulus of elasticity and an ability to
withstand thermal shock. This makes the material suitable for
castings subjected to local or repeated stressing.
