Introduction
High-performance and world-class steel products supplied by ArcelorMittal are a pinnacle component of the rapidly growing energy industry. Our robust yet unique catalogue of products and solutions support oil and gas exploration and production, transport, refining and storage, as well as for the thermal, nuclear and renewable energy industries. The products we offer are produced using American-made steel substrate from one of six domestic steelmaking and finishing facilities for hot rolled and plate. Our R&D expertise, robust product offering, domestic steelmaking capabilities, and proven experience make ArcelorMittal USA the right choice for energy customers.
Line pipe and OCTG
ArcelorMittal is the leader in delivering a variety of steel grades and solutions to line pipe and Oil Country Tubular Goods (OCTG) customers, meeting the most sophisticated requirements. We meet Made & Melt in USA requirements. Our line pipe portfolio includes all API grades through X-80, including sour service applications. These grades are available in both hot rolled coils and plates in a variety of thicknesses and widths.
Innovative steel solution: Pipe ring forming equipment and ring expansion test
| Challenge | Mechanical properties of flat products change when formed into cylindrical pipes. Curved samples from cylindrical pipes must be flattened to make tensile specimens, which alters mechanical properties. The magnitude of these changes varies with wall thickness, pipe diameter, and forming/flattening processes. |
| Solution | Our global R&D team has invested in new equipment to simulate the pipe forming process and eliminate specimen flattening. This includes a roll bending machine that allows full thickness coil/plate samples to be formed into actual diameter cylinders simulating the deformations of pipe manufacture. A complimentary ring expansion test unit capable of measuring the yield strength of 16-48-inch diameter pipe in the native pipe cylindrical form provides a more accurate measure of strength in pipe form. |
| Value | - Pipe skelp design with robust property performance
- Pipe mills have high confidence of meeting properties in pipe form
- Validation of true material performance of pipe without the uncertainty associated with specimen flattening and tensile testing

Wind energy
Steel is used to create many parts of the wind tower from the base up to the gearbox, but the most obvious steel component is the tower itself. ArcelorMittal can supply plates and hot rolled steels for this application whether the application is onshore or offshore.
Innovative steel solution: Modeling and simulation tools
| Challenge | Higher towers require higher tensile properties and/or thicker plates to handle increased loading. Larger towers are transported in pieces and must be assembled in the field. |
| Solution | Our global R&D team is actively researching new tower designs and methods of assembly with both mechanical fasteners and welding technology. Simulations are performed on proposed designs to evaluate performance and optimize material utilization. |
| Value | - Welding expertise
- Shorter design timeline
- Higher efficiency
- Larger turbines

Solar energy
Solar panel mounting structures are designed to perform in the geographic area of installation based on corrosion requirements and wind loading. Cost and longevity are key inputs to the designs. Heavy zinc coatings are available in a variety of strength levels to allow for more flexibility in design. High-concentrating PV requires heavy duty structures and tracking hardware to enable the design efficiencies. Thick steel boxes and heavy tubular structures are commonly specified. Concentrated solar thermal power requires precision positioning of mirrors to accurately focus the sun light. Stiffness and strength are important as is resistance to corrosion and abrasion. Molten salt used for energy capture and transfer is extremely corrosive and special steels are required to contain it. ArcelorMittal has material solutions ready to address your design challenges.
Innovative steel solution: Modeling and simulation tools
ArcelorMittal is actively developing new products specifically for the solar racking market, including ultra-high strength steels with superior corrosion resistance such as SS Grade 95. Our team of R&D engineers can help to optimize your design though computer simulation and recommend grade options. In addition, ArcelorMittal is also involved in providing complete solutions to the solar market through Exosun. From material supplier to solutions provider, ArcelorMittal is there to help.
Oil and gas (offshore, storage tanks, LNG)
ArcelorMittal USA supplies the oil and gas industry with plate products for the construction and maintenance of offshore platforms and onshore facilities including refineries, petrochemical, liquid natural gas (LNG), and fuel storage. Recommended products include 9Ni, API 2Y and ABS grades.
Innovative steel solution: High strength 9 percent nickel steel
| Challenge |
9Ni steel is the traditional solution for use in cryogenic applications like LNG storage. This steel grade containing 9 percent nickel has a high and variable cost due to alloy content. |
| Solution |
A new high strength 9Ni steel grade has been developed with improved tensile properties. |
| Value |
- The higher strength and excellent properties of the new 9 percent nickel steel enables weight reduction for the tank or other cryogenic applications.
- Lighter tanks use less nickel thus lowering material costs.
- Lighter tanks allow for increased transport capacity or lower transportation costs.

Transmission
Transmission towers and light poles require long life and protection against corrosion. Weathering steels have copper additions that promote the development of a protective oxide for increased corrosion life. Recommended products include weathering steels and Amstrong® Ultra.
