Welcome to Special Quality Alloys Inc.


Established in 1999, Special Quality Alloys Inc is part of the Special Steel Group. Our expertise is the distribution of bars and forgings in nickel-based superalloys, duplex, super duplex, martensitic and high strength stainless steels. You’ll find our materials operating in critical equipment around the world.


Who we are

Special Steel Co Ltd was originally founded in 1925 by Bennett Beardshaw with the intention to melt and process tool steels.

The company went from strength to strength, establishing companies – Special Testing Ltd and STW (Non Destructive) Ltd - to provide complementary services to an expanding customer base.

Special Quality Alloys was established in 1986 to supply nickel-based superalloys and specialty steels, a service that was made international in 1999, when Special Quality Alloys Inc was set up in Humble, Texas.

In the late 1990s, the Group grew through investment and merger, taking over G H White and Co Ltd in 1997 and Hawk Engineering in 1999. The former was a heat treatment sub-contractor specializing in smaller components, thereby extending the range offered by Special Steel; the latter provided machining services, and was rebranded Special Machined Products Ltd.

In 2011 Sheffield Quality Forge Ltd was established to provide both sub-contract and full supply of forgings. In 2015 SQA & SQF merged due to the complimentary nature of their products and customers.

Today, Special Quality Alloys utilizes not only its own extensive range of facilities and qualified people, but also has access to Group company plants and expertise, providing our customers with metals processing that is truly world class.

We hold approvals required by the oil and gas industry including IS0 9001, ISO 14001 and numerous end user approvals.

Our processing techniques, manufacturing controls, and quality procedures have been audited by many of the oil companies including BP, Shell, Exxon Mobil, Total, Chevron, Statoil and Petrobras.

And with representation in the Far East, South America and Continental Europe, Special Quality Alloys truly is a global one-stop-shop for critical, high-value oilfield grades and products.
