Steel is the skeleton of the modern world — some 1.9 billion tonnes of it a year — and it is made by a smaller club than at any time in its history: a Chinese state champion twice the size of its nearest rival; a Luxembourg group built by one family across five continents; a Japanese leader that has just absorbed America's most famous steelmaker under a United States Government golden share; the great state majors of China, India and Taiwan; Korea's twin champions; India's growth engines; America's mini-mill revolutionary and its automotive roll-up; and Europe's technology-led survivors, restructuring for hydrogen and scrap. This guide maps the 25 companies that matter most — who leads each in October 2026, with exact published titles; what each makes, in full; whom it serves; how large it is, with every figure dated and sourced in the entry; where its works stand; and how it is owned — with every gap named rather than filled.
The ranking follows the World Steel Association (worldsteel), World Steel in Figures 2026 — crude steel production for 2025. Where a company sits below that table's cut, or its tonnage is consolidated inside a parent, the entry says so and labels the basis it does use. U.S. Steel appears as its own entry because its story — and its governance — is unlike any other in the guide: since 18 June 2025 it has been a wholly owned subsidiary of Nippon Steel, delisted, Pittsburgh-headquartered, American-led, and subject to a United States Government golden share whose consent rights are set out in full in its entry and in Named Gaps below. Its tonnes are counted once, inside Nippon Steel's total.

Formed in 1901 as the world's first billion-dollar corporation (capitalisation US$1.4bn), combining Andrew Carnegie's Carnegie Steel with Elbert Gary's Federal Steel; the emblem of American integrated steelmaking for a century (Gary Works named for its first chairman); built the Big River Steel EAF works (Arkansas, acquired in full 2021); acquired by Nippon Steel on 18 June 2025 — see Notes and the status statement in Named Gaps. The most politically significant steel transaction of the century: a Japanese acquisition of America's iconic steelmaker, closed only with a U.S. Government golden share — the governance arrangement is stated in full in Notes and Named Gaps.
STATUS AS OF OCTOBER 2026 (verified): U.S. Steel is a wholly owned subsidiary of Nippon Steel Corporation. The acquisition (US$55.00 per share, approx. US$14.9 billion equity value) closed on 18 June 2025 and U.S. Steel was delisted from the NYSE the same day. It retains the U.S. Steel name and its Pittsburgh headquarters, is led by an American CEO (David B. Burritt) with a majority-U.S.-citizen board, and operates under a National Security Agreement with the U.S. Government. Under that agreement the Government holds a golden share giving the President consent / veto rights over, among other matters: relocating the Pittsburgh headquarters; redomiciling outside the USA; changing the company name; reducing, waiving or delaying the committed capital investments (approx. US$14 billion of commitments referenced in Government statements, including approx. US$11 billion of new investment by 2028 announced by Nippon Steel); transferring production or jobs outside the USA; and closing or idling plants other than in the ordinary course, and the right to appoint one independent director. Nippon Steel has stated the arrangement preserves its management freedom for ordinary business investment. U.S. Steel is therefore listed in this guide as a distinct operating company within the Nippon Steel group, and its tonnage is counted once — inside Nippon Steel.

Linz works founded 1938; post-war VOEST became Austria's steel champion and inventor-marketed the LD (Linz–Donawitz) basic oxygen process (1952) that remade world steelmaking; merged steel / technology groups formed today's voestalpine — a processing-led group (railway systems, tool steel, automotive components) rather than a tonnage steelmaker. The process inventor in the guide: the LD process was born at Linz and Donawitz; today voestalpine earns its margin in rails, tool steel and components, not tonnage — and its greentec steel EAFs (2027) are Austria's largest climate programme.
Output basis is labelled company-basis precisely because voestalpine sits below the worldsteel headline table — no ranking is claimed for it.

Ken Iverson built Nucor from the Nuclear Corporation of America into the pioneer of the scrap-based electric-arc mini-mill (Darlington, 1969, with Nucor Steel and Vulcraft joist lineage); decentralised 'teammate' culture and pay-for-performance became the model that displaced integrated scale in the USA; largest US steelmaker since the 2000s. The mini-mill revolutionary: the most profitable US steelmaker of the modern era, built on scrap, EAFs, a sub-100-person head office and no unions — and now the largest US producer by output.
Laxton's combined President / COO / CFO role (from 1 Jan 2026) is unusual and is stated exactly as the company publishes it.

Europe's steel heritage in one group: Friedrich Krupp (Essen, 1811) and August Thyssen (Duisburg, 1891) merged as thyssenkrupp in 1999; the Steel Europe business (Duisburg — Europe's largest steel site) is being restructured under the group's published plan, with a planned joint venture with Jindal Steel International (MoU / sale process for Steel Europe announced 2025 — recorded as a process, not a completed sale, at press time) and capacity / job reductions under the 'Steel Strategy 20-30' lineage and the 2024–25 restructuring agreement with IG Metall. Included as context by design: Europe's largest steel site at Duisburg, a 20% Křetínský stake, a hydrogen DRI plant under construction and a live ownership process (Jindal interest, 2025) make Steel Europe the continent's steel story in miniature — even below the tonnage cut.
Ownership-process note is dated October 2026 and records a process / MoU-stage interest, not a completed change of control. Leadership detail beyond Group CEO and Steel CEO is a named verification limit, not an omission by design.

NAMED GAPS
Ansteel, Shougang (group leadership in English): neither group publishes a full leadership roster in English in sources consulted; the entries name the structure (Chairman / General Manager under SASAC or Beijing SASAC) and state the gap rather than printing aggregator rosters.
Shagang and Jianlong (private groups): beyond founder-Chairmen Shen Wenrong (Shagang) and Zhang Zhixiang (Jianlong), executive rosters and group revenue are not published in English official sources; output is carried on the dated worldsteel basis only.
China Steel Corporation and Erdemir (incumbent check): both publish leadership, but the English-page incumbent verification for October 2026 could not be completed in sources consulted, so no possibly stale name is printed.
SAIL Director (Finance) and Gerdau Board Chairman: left as stated gaps under the same verification standard — the operating chief executives (SAIL CMD Amarendu Prakash; Gerdau CEO Gustavo Werneck) are verified and printed.
U.S. Steel post-closing disclosure: as a wholly owned, delisted subsidiary (from 18 June 2025), U.S. Steel no longer publishes listed-company leadership / financial detail on the old basis; its CEO is verified from closing materials, its FY2024 revenue is labelled the last pre-acquisition year, and its tonnage is counted once, inside Nippon Steel.
thyssenkrupp Steel Europe and Salzgitter detail: board detail beyond the chief executives named is published in German corporate pages and is summarised, not reproduced, here; both are included below the worldsteel top-table tonnage cut and their output cells are labelled company-basis.
Contact emails: no company in this guide publishes a general corporate email address in sources consulted — every entry therefore prints the published route (web form / IR page / published phone where one exists) and marks email 'Not published'. No address has been guessed.
Chinese group revenues: for Baowu, Ansteel, HBIS, Shagang, Jianlong and Shougang, English-language group filings are limited; scale cells label their basis (listed arm, sustainability report, Fortune reporting or 'not published') in every case.
U.S. Steel status note: As of October 2026, United States Steel Corporation is a wholly owned subsidiary of Nippon Steel Corporation (closed 18 June 2025; delisted from the NYSE the same day), retaining its name, its Pittsburgh headquarters, an American President and CEO (David B. Burritt) and a majority-U.S.-citizen board, under a National Security Agreement giving the United States Government a golden share — presidential consent rights over headquarters relocation, redomiciling, a name change, reduction or delay of the committed investments, transfer of production or jobs abroad, and plant closures or idling outside the ordinary course, plus the right to appoint one independent director. Its output is counted once in this guide, inside Nippon Steel’s worldsteel total.
