We are a world-class supplier of engineering raw materials. Our objective is to provide all our customers, from the small machine shop to the large multi-national corporation, a supply path that continuously delivers the highest levels of service, quality and value.
Alloy 440C has the highest carbon content of all 440 series stainless steel and is more readily available than 440B.
The product is highly suitable for use in applications where greater strength and moderate corrosion resistance is a consideration. Although the alloy has a higher carbon content, there is enough chromium content to retain the materials stainless steel characteristics. Once heat-treated, 440C achieves the highest hardness and wear resistance of any stainless steel currently available. It is particularly suited to applications such as valve parts and bearings.
Alloy 440C is relatively easy to machine in the annealed condition. Machining of the alloy is much more difficult when hardened. The manufacturing specification for Alloy 440C is AMS A276.
Commercial applications for this engineering material include:
We stock 440C in flats, round bar and sheet.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
