Нержавеющая сталь 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 Нержавеющая сталь 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.
Глубокое введение
Deep dive: Нержавеющая сталь
Нержавеющая сталь (Fe–Cr–Ni (±Mo, N, C)) is a family of grades whose density ~8.0 g/cm³, heat band ~1400–1450 °C, and fire letter A1 metal.
What “the material” actually is
Нержавеющая сталь is sold as grades, not as a single substance. Chemistry Fe–Cr–Ni (±Mo, N, C), density ~8.0 g/cm³, heat band ~1400–1450 °C.
This atlas treats Нержавеющая сталь as a system: mill route, coatings, tests and the cavity it sits in.
Heat, fire and insulation
Conductivity note: ~15 W/m·K (austenitic). Insulation score 10/100 is relative to 32 entries — metals lose, VIPs and aerogels win.
Fire letter in editorial use: A1 metal. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
