Rubiera Special Steel

What Rubiera Special Steel does

Rubiera Special Steel S.p.A. is an Italian privately held specialty steelmaker founded in 1965, headquartered in Casalgrande (province of Reggio Emilia) and operating as a public limited company (S.p.A.) with a declared social capital of €1,000,000 I.V. The company specializes in high-integrity steels produced through vacuum degassing, Electro-Slag Remelting (ESR) and Vacuum Arc Remelting (VAR), with ingot capabilities spanning 1.5 to 145 tons and a portfolio that includes remelted ingots and forged bars. It serves enterprise customers primarily in the Power Generation and Oil & Gas sectors, supplemented by industrial manufacturers, and supplies additional segments including bearing steel.

The company operates two distinct production divisions. The Special Steel Division at the Casalgrande plant is the legacy operation and the historic site where Rubiera became the first Italian steelmaker to introduce vacuum degassing. The Stainless Steel & Alloys Division at Cividate al Piano (province of Bergamo) was acquired in 2024 and is scheduled to begin production in 2026, extending the product range into stainless steels and special alloys with ingots up to 100 tons, forged bars up to 70 tons, and VAR/ESR remelted ingots. Both divisions offer customized production services, including grinding (200–1800 mm) and cutting (up to 2500 mm), with an ISTEEL client portal supporting customer interaction.

Rubiera pursues a direct enterprise field-sales motion targeting major Power Generation and Oil & Gas manufacturers, with a stated focus on building long-lasting strategic partnerships. Pricing is quote-based and not publicly disclosed, and revenue is generated through hardware sales of specialty steel products. The company maintains an unusually broad certification stack — including ISO 9001, ISO 14001 (since 2003), ISO 45001, ISO 50001, EMAS, and classification society approvals from DNV-GL, Lloyd's Register EMEA, NKK, ABS, Bureau Veritas (Materials and Mode II Scheme), RINA, and TÜV SÜD — which is effectively a precondition for supplying safety-critical components into its target end-markets. It also runs a co-development R&D partnership with the Material Engineering Department of the University of Modena.
