Eisen–Kohlenstoff-Arbeitstier für Bau, Schiffe und Schienen — endlos umgeschmolzen.
Auch genannt: Baustahl · structural steel · iron–carbon alloy
Stahl is one of 32 materials in this atlas, grouped under metals: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue.
Scores compare Stahl with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.
Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
Tiefe Einführung
Stahl (Fe–C (±Mn, Si, Cr…)) is a family of grades whose density 7.85 g/cm³, heat band 1370–1530 °C, and fire letter A1 as construction steel.
Stahl is sold as grades, not as a single substance. Chemistry Fe–C (±Mn, Si, Cr…), density 7.85 g/cm³, heat band 1370–1530 °C.
This atlas treats Stahl as a system: mill route, coatings, tests and the cavity it sits in.
Conductivity note: ~50 W/m·K. Insulation score 8/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: A1 as construction steel. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: bloomery c. 1800 BCE / Bessemer 1856, Anatolia → Sheffield. The process chapter follows feedstock → conversion → forming → finish → install.
Uses span construction to packaging. Pairings matter: Concrete.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 64/100. Ask which scrap, which certificate, which year.
