Alloy 825 (UNS N08825) is an austenitic nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It was developed to provide exceptional corrosion resistance in both oxidizing and reducing environments. The alloy is resistant to chloride stress-corrosion cracking and pitting. The addition of titanium stabilizes Alloy 825 against sensitization in the as-welded condition making the alloy resistant to intergranular attack after exposure to temperatures in a range that would sensitize unstabilized stainless steels. The fabrication of Alloy 825 is typical of nickel-base alloys, with material being readily formable and weldable by a variety of techniques

AMETEK Specialty Metal Products has been a leader in developing roll bonding dissimilar metals for more than fifty years. The advantage of clad materials is the end product combines the superior properties of each metal: Strength, Corrosion Resistance, Lightweight, Cost, Thermal and Electrical Conductivity. As a result, clad products produce a material superior to any of the individual metals taken alone.
Clad metals produced by our roll bond technology combine two or more metals into a single sheet or plate that can be cut, welded or formed into a finished part ranging from chemical processing chambers and pressure vessels to small applications and clad pipe. We specialize in cladding stainless steel or nickel alloys to carbon steel as well as triple layer clad plates bonding stainless steel to an aluminum core.
Because of the properties offered by clad metals, and the wide variety of cladding and backing materials available today, these metals can be combined to make custom
Our NORSOK-approved Super Duplex alloy 2507 tubes (UNS 32750) are custom-engineered for the most aggressive subsea and downhole oil and gas applications.
Advantages include:
NORSOK-approval
Made to order in specialist non-standard sizes
Superior strength and corrosion resistance
Short lead times
Small batch sizes
With 80 years engineering expertise, we specialise in manufacturing corrosion resistant Super Duplex tubes for the increasing hostile temperature and operating environments.
Greater Corrosion Resistance Than Standard Duplex Grades
Super Duplex stainless like S32750, is a mixed microstructure of austenite and ferrite (50/50) which has improved strength over ferritic and austenitic steel grades. The main difference is that Super Duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance than standard duplex grades.

Major engineering companies who design and manufacture aerospace engines rely on the strength and durability of tubing products made at the Superior Tube mill. This is due to our reputation for producing high quality, high strength, yet lightweight tubing.
You’ll find our tubes at work within a variety of systems in aircraft including fuel delivery, fire suppression, drain lines and bleed air systems. Bleed air is high temperature, high pressure air taken from the jet engine and fed into various areas of the plane to be used for things like de-icing and cabin pressurization.
We use high performance materials such as Alloy 321 stainless steel and Inconel 625 and 718 for applications that deal with extreme temperatures. Precision tubing for aerospace engines can be ordered in sizes from 0.250” outside diameter right up to 1.5”.

Our metallurgists specialize in the design, development and production of specialty metal powders manufactured through advanced high-pressure water atomization technology. We work alongside our customers to develop custom metal alloy powder solutions to exacting specifications for critical applications.
Our expertise and nearly 50 years of history in water atomization of specialty metal powder products has led us to supply a huge number of market sectors ranging from automotive to semiconductor to aerospace across the test globe.
Water Atomization Process
We employ an advanced high-pressure water atomization process to engineer highly customized metal powder. Our technology is proven to achieve fine particle size distributions, enabling our metallurgists to produce precision metal powder products.
We have a long and established history in serving the global Powder Metallurgy industry with substantial historical product developments and leadership representation at Metal Powder Industries Federation (MPIF). Our ability to engineer customized, structural metal powders through water atomization for Powder Metallurgy (PM) applications is world renown, particularly in the automotive and industrial markets.
Powder Metallurgy (PM) is the process of pressing and sintering a metal powder into a near net shape part that offers numerous advantages over other metal forming technologies including:
High customization such as size, alloy and properties
Cost effectiveness and sustainability due to near net shape or net shape production
Shape complexity without secondary operation
