The steel you specify for a pressure vessel, tower, column, heat exchanger, or stack drives every downstream decision: weld procedures, inspection, code compliance, and lifecycle cost. Boardman LLC fabricates custom industrial equipment in carbon steel, stainless steel, clad materials, chrome moly (Cr-Mo), and high alloys, with corrosion-resistant overlay available for equipment requiring internal surface protection.

Steel fabrication materials are the base metals and alloys used to build custom industrial equipment to ASME code and project specs. Selection depends on operating pressure, design temperature, process media, corrosion exposure, weldability, and inspection requirements. Boardman provides full material traceability and documentation on every project.
Boardman can work from your drawings and specifications, or help you evaluate fabrication material options before you finalize your RFQ.

*High alloy metals include Incoloy, Inconel, Nickel, Hastelloy, Duplex, and Monel.
Have you ever worked with a fabricator who had an “Our Way or the Highway” approach? Or one that left you wondering whether your project would be finished on time?
At Boardman, you get the fabrication materials you need and the level of stewardship that keeps your project on track. Your options include:
Boardman holds ASME Section VIII Div. I and Div. II authority, along with National Board U Stamp, National Board R Stamp, AISC, API, and AWS certifications. These credentials reflect a commitment to code compliance, quality control, and fabrication integrity that your project depends on.
You will be kept informed and involved as much or as little as you want. That is a promise Boardman has been keeping since 1910.
No single material is right for every application. The right choice depends on a combination of process and project factors. The table below is a starting point for your material specification discussions.
Key selection variables:
| Material | Common Reason to Choose It | Typical Boardman Applications |
|---|---|---|
| Carbon Steel | Strength, weldability, and cost efficiency | Pressure vessels, drums, towers, columns, stacks, separators |
| Stainless Steel | Corrosion resistance and cleanability | Chemical equipment, pressure vessels, tanks, scrubbers |
| Clad Material | Carbon steel strength with alloy corrosion resistance at the wetted surface | Pressure vessels requiring structural strength and internal corrosion protection |
| Chrome Moly (Cr-Mo) | Elevated temperature strength and improved corrosion performance | High-temperature vessels, reactors, refinery equipment |
| High Alloy Metals | Specialized corrosion, temperature, or process requirements | Nickel, Incoloy, Inconel, Hastelloy, Duplex, or Monel fabrications |
Boardman can work from your customer-supplied drawings and specifications, or help your team think through material considerations before you finalize your RFQ.

Boardman’s approach is built on stewardship, precision, and the project management and quality control that give engineering and procurement teams confidence from kickoff through delivery.
Have questions? Here are answers to the things engineering and procurement teams ask most often.
Boardman fabricates equipment using carbon steel, stainless steel, clad materials, chrome moly (Cr-Mo), and high-alloy metals, including Nickel, Incoloy, Inconel, Hastelloy, Duplex, and Monel. Material selection depends on your process conditions, code requirements, and project specifications.
There is no single answer. Selection depends on design pressure, design temperature, process media, and corrosion environment. Carbon steel is common for general service. Stainless steel or alloy materials are specified when corrosion or temperature conditions require it. Boardman can help evaluate options for your application.
Clad material bonds a corrosion-resistant alloy layer to a carbon steel or low alloy backer. The carbon steel provides structural strength while the alloy layer protects the wetted surface. It is often more cost-effective than a full solid alloy shell when only the interior requires alloy performance.
Yes. Boardman fabricates equipment using stainless steel, clad materials, and high alloy metals for corrosion-sensitive applications. Boardman also offers cladding and corrosion-resistant weld overlay for equipment requiring internal surface protection. Contact Boardman to discuss your corrosion requirements.
Boardman serves refining, chemical, petrochemical, gas processing, biofuels, hydrogen, emission control, carbon capture, carbon black, lithium, and cryogenic industries. If your application requires ASME-compliant fabrication in any industrial setting, contact Boardman to discuss your project.
The material you specify affects code compliance, weld procedures, inspection requirements, and the long-term performance of your equipment. Since 1910, Boardman has fabricated ASME pressure vessels, trayed towers, columns, drums, heat exchangers, reactors, stacks, and heavy plate equipment from its Oklahoma City facility, using carbon steel, stainless steel, clad materials, chrome moly (Cr-Mo), and high-alloy metals for clients nationwide.
Whether you bring your drawings or need help thinking through material considerations first, Boardman is ready to support your project.
