Stainless steel in 1990s: Super duplex / 6Mo
Read the condition on Stainless steel before the nickname. Year 1990s, line “Super duplex / 6Mo,” figure 6. Molybdenum for chlorides in marine and pharma. A material is what it is made of, the condition it survives, and where it goes afterward. Stainless steel under “Super duplex / 6Mo” in 1990s should say which, with 6 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
This atlas treats Stainless steel as a system: mill route, coatings, tests and the cavity it sits in. 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.
Origin: 1913 Brearley / Strauss, Sheffield / Essen. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: steel. Circularity mark 68/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Stainless steel honest.
The parent without the chromium film. Different corrosion colour language. The other hygienic surface in pharma. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation. Declared performance after blowing-agent or moisture drift.
The label keeps Stainless steel, 1990s, and 6. “Super duplex / 6Mo” is the condition on the figure.1990s
