Important Message

Dear Customer,

After 123 years of trading, Charles Butcher and Co Ltd, and its operating company, Durham Foundry (Sheffield) Ltd, are ceasing trading. This has not been an easy decision but the board believes that it is the right time to do so and is in the best interests of the shareholders. This is a planned closure and the companies are wholly solvent.

Current orders will be honoured but we will be unable, unless specifically agreed, to take on any new work.

To enable the closure to happen as smoothly as possible, we have entered into an agreement to try and transfer work to Canlin Castings Ltd. They are a similar foundry to Durham Foundry offering the same range of material grades, quantities and weights. Their details are:-

Canlin Castings Ltd,
North Street,
Langley Mill,
NG16 4DF

Tel: 01773 715412

The contact there, to discuss how work may be transferred, is David Carlin who can be contacted at

If you wish to discuss anything regarding the closure, please contact me on 0114 249 4977 or email me at

Mike Naylor
Chairman and Managing Director

Wear Resistant & Ni Hard Cast Iron Castings

Cast iron, in grades normally used for items such as bearing housings, gearboxes or machine beds, has a hardness of about 150 to 200 Brinell. With the addition of alloying elements, usually chrome, nickel or copper, the hardness can be increased to over 700 Brinell. This has opened up the use of cast iron into areas where wear resistance is a crucial requirement.

About Wear Resistant Ni Hard Cast Iron Castings

At Durham Foundry we have been producing wear resistant iron castings for over twenty five years. As well as castings for wear resistant applications, our customer base also covers 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 moulders can work from complex loose pattern equipment, particularly where low volumes are required, whilst our moulding line is suited for batch production. 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 abrasion resistant castings and continue to be so.

Ni Hard Cast Iron Castings Examples

Examples of these uses include mixer paddles, augurs and dies in the clay industry, liner plates for ball mills and coal chutes, wire guides for wire drawing and shotblast spares. Call Durham Foundry on 0114 249 4977 to discuss your Wear Resistant & Ni Hard Cast Iron Castings project.

Ni Hard Cast Iron Casting Certification

All our wear resistant castings are produced to the current ISO material specification, ISO 21988 2006, along with any further certification which a customer may require. Our diverse customer base has also given us experience in a wide range of other applications for 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 Wear Resistant & Ni Hard Cast Iron Castings.

Ni Hard Cast Iron Casting & Wear Resistance

Wear resistance can be achieved in cast iron in two basic ways. Firstly a normal grey iron can have small additions of copper, molybdenum, vanadium or chrome added. These are usually up to 1% and can increase the hardness from a base of about 150 Brinell up to 200 to 300 Brinell by promoting the formation of pearlite in the casting, particularly if the carbon and silicon levels are controlled to the lower end of the desired range. If these hardness’s are sufficient, this method has the advantage that the resultant alloy is still machinable.

The second method involves the use of chrome and nickel in much higher quantities, the chrome content being as high as 28% to create a structure that includes a high proportion of primary carbides. Although a lot of chrome iron castings are supplied in the as cast state, these alloys are heat treatable, which promotes the growth of secondary carbides, and can attain hardness’s as high as 700 Brinell.

Tempering can be used to increase the toughness. This second method is, unfortunately, only machinable using special techniques and cutting processes which usually results in castings that are cast to size. Where fixings are required it is possible to cast in threaded bars or blocks of steel that can be drilled and tapped after the casting is made to give fixing and location points.

Wear Resistant Ni Hard Cast Iron Castings Methods

There are a number of ways of describing this highly alloyed type of iron – Chrome Iron, Wear Resistant Iron, Ni Hard or 28% Chrome being the more common ones, along with a range of national and international standards. This can cause some confusion and at Durham Foundry we are happy to advise on a suitable grade that will give the wear resistance required. One side effect of the levels of chrome and nickel used in these grades is that they can have good corrosion resistance which can lead to alternative applications.

Also, given the inherently higher melting point of chrome compared to cast iron, they can be used for heat resistant castings, particularly if the carbon content is controlled to the lower end of the permissible range in some of the 28% chrome grades. These heat resistant versions have applications in castings such as fire bars and grate assemblies in stoves.
