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.

How it is made and used

Origin: 1913 Brearley / Strauss, Sheffield / Essen. The process chapter follows feedstock → conversion → forming → finish → install.

Uses span buildings to defence / safety. Pairings matter: steel.

Market and circularity

Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.

Circularity mark 68/100. Ask which scrap, which certificate, which year.
