American Alloy Fabricators has the experience and expertise to meet the most challenging demands of the chemical, pharmaceutical, biotechnology, and food processing industries. With our alloy fabrication capabilities, we can deliver a range of quality products to fit the needs of various applications. 

Our Custom Alloy Fabrication Metal Services

As part of our custom alloy fabrication services, we offer professional chemical and mechanical engineering consulting. Although American Alloy Fabricators’ specialty is in producing reactors, vessels, and tanks, our extensive product development experience and skilled craftsmen enable us to meet even the most challenging custom metal fabrication needs. We also aid in the research and development of custom-fabricated metal products.

What Materials Can You Use for Alloy Fabrication?

We can work with the following materials:

  • Stainless Steel. Stainless steels come in various types, including austenitic stainless steel. This non-magnetic material contains high nickel and chromium content and is widely used due to its formability and corrosion resistance.
  • Hastelloy. Hastelloy refers to a nickel metal that has been alloyed to enhance corrosion resistance. The most common alloyed materials include chromium and molybdenum. Hastelloy comes in various grades, each with a distinct chemical composition that offers a unique set of properties.
  • Inconel. Inconel is a high-performance metal designed for use in extreme applications. Since Inconel is less widely used and more expensive, it’s not as common as aluminum or steel. 
  • Monel. A metal superalloy, Monel® (cupronickel) consists of roughly 20-29% copper, 65-70% nickel, and 5% manganese. Materials made from the Monel® nickel-copper alloy resist corrosion from chemicals, alkaline solutions, salt water, and acids, making them useful in harsh environments. The most common industries that utilize this material include chemical processing, marine, and oil. 
  • Alloy 20. Alloy 20 is an austenitic alloy composed of nickel, iron, and chromium. It displays remarkable corrosion resistance in the presence of sulfuric acid and other aggressive media. When stabilized with niobium, this alloy gains resistance to intergranular corrosion. Compared to higher nickel-based alloys, Alloy 20 may offer possible cost savings while outperforming typical stainless steels.
  • AL-6XN. This “super-austenitic” stainless alloy is nitrogen-bearing, low in carbon, and high in purity. AL-6XN not only resists seawater but also demonstrates resistance to a wide range of highly corrosive environments. AL-6XN is a better choice than traditional duplex stainless steel due to its corrosion resistance and high strength. It is also a more cost-effective alternative to more expensive nickel-based alloys.

Our Alloy Fabrication Welding Services

Welding techniques and welders must adhere to the standards outlined in ASME section IX of the ASME boiler pressure vessel code. At American Alloy, we are ASME Section IX certified and offer the following welding services:

  • Gas metal arc welding (GMAW). During GMAW, or MIG welding, a consumable wire electrode is fed through the welding gun. Inert shielding gas is sprayed over the welding puddle to prevent contamination. MIG welding’s versatility and ease of use have made it the go-to technique in various industrial settings. However, it is not advisable to use it outdoors or in places with particularly volatile air.
  • Gas tungsten arc welding (GTAW). In GTAW, or TIG welding, a tungsten electrode is used to produce the weld. Rather than the electrode being consumed during the welding process, the weld area is protected from contamination using an inert gas such as helium or argon.
  • Shielded metal arc welding (SMAW). SMAW is often referred to as stick welding due to its electrode, which features a protective flux coating. The “stick” is held in place by an electrode holder, and an electric arc is generated using an alternating or direct current. This causes the electrode to slowly melt while also melting the joining metals. At the same time, the gas vapor released from the flux coating works in tandem with the slag to create a shield that keeps the weld area clean.
  • Orbital. Orbital welding is a form of automated welding that uses a rotating (or orbiting) electrode to weld tubes or pipes together. This is a specialized form of welding in which the arc continuously spins around the pipe or tube while it is in place.

Finishes for Alloy Fabrication

In addition to welding, we also offer finishing services such as:

  • Mechanical Polishing. This process grinds, polishes, and buffs the metal surface to smooth welds, remove contaminants, and prepare the metal for surface treatment such as electropolishing. It can also be used to provide a surface with the desired roughness.
  • Electropolishing. This electrochemical process removes peaks on a nanoscopic level to smooth the metal’s surface. Electropolishing can increase the corrosion resistance of austenitic stainless steels, decrease contamination buildup and product adhesion, deburr and dull sharp edges, and produce a reflective and lustrous finish.
