Acero 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 Acero 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.
Introducción profunda
Deep dive: Acero
Acero (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.
What “the material” actually is
Acero 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 Acero as a system: mill route, coatings, tests and the cavity it sits in.
Heat, fire and insulation
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.
How it is made and used
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.
Market and circularity
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.
