Usages
Ferritic stainless steels are cheaper than austenitic steels and
present in many commercial products, which include:
Building components, such as slate hooks, roofing, and chimney
ducts
Power plates in solid oxide fuel cells operating at temperatures
around 700 °C (1,292 °F) (high-chromium ferritics containing 22%
Cr)
Architectural and structural applications (Type 430, which contains
17% Cr)
Household goods, such as kitchenware, sinks, and major appliances
Automobile exhaust pipes (Type 409 and 409 Cb[2] are used in North
America; stabilized grades Type 439 and 441 are used in Europe)
Invention
Robert Bunsen discovered chromium's resistance to strong acids. The
corrosion resistance of iron-chromium alloys may have been first
recognized in 1821 by Pierre Berthier, who noted their resistance
against attack by some acids and suggested their use in cutlery.
In the early 1800s, James Stodart, Michael Faraday, and Robert
Mallet observed the resistance of chromium-iron alloys ("chromium
steels") to oxidizing agents.
The invention of stainless steel followed a series of scientific
developments, starting in 1798 when chromium was first shown to the
French Academy by Louis Vauquelin.
