What Showa Denko Carbon, Inc. does
Resonac Graphite Business Unit (the entity behind Showa Denko Carbon, Inc.) is a wholly-owned subsidiary of RESONAC Holdings Corporation (TSE: 4004) and operates as one of the world's leading manufacturers of ultra-high-power synthetic graphite electrodes for electric arc furnace (EAF) steelmaking, ladle furnaces, and non-ferrous smelting. The unit produces electrodes in diameters from 350–800 mm across four manufacturing sites — Ridgeville, South Carolina (Americas HQ); A Coruña, Spain and Bad Goisern, Austria (EMEA); and Omachi, Japan (sole-source PIN manufacturing for all global sites) — and serves enterprise steelmakers via direct regional sales organizations in the Americas, EMEA, and Asia. Its product portfolio now also spans Battery Anode Materials (BAM) for electric-vehicle lithium-ion batteries following the January 2025 integration of the Energy Storage Materials and Tribology (ESTM) business line, as well as carbon brushes, sliding materials, and granulated graphite.
Commercially, the business operates a direct enterprise field-sales model with multi-year GE Bundle contracts, quote-based pricing, and technical service support through regional ATC-E centers. The September 2024 announcement of a minimum 20% global price increase on new orders signals coordinated industry response to prior oversupply, while AMI Automation (Mexico) provides an integrated software-and-hardware layer — DigitARC PX3 electrode regulator, SmartARC/SmartFurnace modules, AI Expert Systems, scrap classification, and DC furnace power rectifiers — that ties consumable electrode sales to long-term EAF optimization engagements.
Differentiators include a century-long legacy in graphite manufacturing, unique PIN technology, the world's first third-party verified Environmental Product Declaration for graphite electrodes, renewable-electricity-backed production at the Austria and Spain plants (100% and 40% respectively), ISO 9001/14001/45001/50001 certifications, EcoVadis medals, and university research partnerships via the Resonac-UDC Sparking Truth Chair. The unit is positioned as a sustainability-led graphite platform spanning steelmaking decarbonization, EAF automation, and EV battery materials.

Products and services
- Graphite Electrodes Ultra-high-power synthetic graphite electrodes manufactured in standard diameters from 350mm to 800mm (14–32 inches) and lengths from 1,500mm to 3,600mm (60–142 inches), with typical weights of 0.3–3.2 tons. Used as consumable electrodes in Electric Arc Furnace (EAF) steelmaking, ladle furnaces, and non-ferrous smelting applications. Designed for steel producers requiring low consumption rates (1–2 kg graphite per ton of liquid steel), high thermal performance (3,500°C arc temperature), and 45–90 minute cycle times.
- ΩMEGA Electrode Ladle furnace electrode manufactured in Europe using 100% renewable electricity. Developed to address unmet customer needs for sustainable ladle furnace performance.
- Connecting Pins Graphite electrode connecting pins that join multiple electrodes together in the EAF column assembly. Manufactured exclusively at the Omachi Plant in Japan using unique PIN manufacturing technology that serves as the sole source for all six global production sites.
- Battery Anode Material (BAM) Graphite anode material for Lithium-Ion Batteries used in electric vehicles (EV) and energy storage systems. Enhances battery fast-charging capability and lifetime. Resonac is developing an innovative production process that significantly reduces CO2 emissions compared to conventional methods — graphite represents only ~10% of battery cost but approximately 50% of the CO2 footprint.
