Austenitic cast iron is produced by taking a normal grey or ductile iron melt, controlling the carbon and silicon at lower levels and adding various alloys to produce a stable austenitic structure at ambient temperature. Nickel is the main alloying element, hence the alternative name of Ni-Resist, and is the principle reason why the casting has an austenitic structure with nickel stabilising the austenite during solidification.
Austenitic Castings & Ni-Resist Cast Iron Expense
Because of the nickel content, austenitic cast iron is more expensive than grey or ductile cast iron but is usually cheaper than an equivalent alloyed steel, particularly if the cost of machining the casting is taken into account. It is far easier to machine than a nickel chrome steel.
At Durham Foundry we have been producing austenitic iron castings for over twenty-five years. As well as austenitic iron castings, our customer base also covers grey, ductile and alloyed irons for the engineering, decorative, architectural and artistic sectors and we can supply castings from one-off up to small to medium batch production using Alkali Phenolic resin bonded sands. Our workforce of highly skilled molders can work from complex loose pattern equipment, particularly where low volumes are required, whilst our molding line is suited for batch production.
Austenitic Castings & Ni Resist Cast Iron At Durham Foundry
Our long trading history, coupled with an investment programme that has enabled us to keep up with modern production methods and environmental legislation has meant that we have been involved with many projects requiring austenitic iron castings and continue to be so. All our austenitic iron castings are produced to the current ISO material specification, ISO 2892 1973, along with any further certification which a customer may require.
Our diverse customer base has also given us experience in a wide range of applications for austenitic iron castings, including pumps and valves, forges, foundries and rolling mills, automotive and aerospace, a wide range of OEM’s, quarries and mines, railways and rolling stock, local authorities and artists and sculptors.
We also have long-term trading relationships with local pattern makers, machine shops and surface finishers which enable us to quote for the complete supply of the finished casting. In many cases we project manage the whole process and offer expertise in Austenitic Castings & Ni-Resist Cast iron. Call Durham Foundry on 0114 249 4977 to discuss your Austenitic Iron Castings & NI Resist Cast Iron project.
