Decoufle Nano Circular Knife For Cigarette Filter Cutting
Filter Knife is a component of cigarette making machines to slice
filter rod after being connected to cigarette rod.
1. Ferric Oxide Formation
addition of molybdenum (which also improves resistance to "pitting
corrosion")
increasing the chromium content to levels above 11%;
Stainless steel's resistance to ferric oxide formation results from
the presence of chromium in the alloy, which forms a passive film
that would protect the underlying material from corrosion, and can
self-heal in the presence of oxygen. Corrosion resistance can be
enhanced further, by:
addition of 8% or higher amounts of nickel
2. Material Invention
In the early 1800s, James Stodart, Michael Faraday, and Robert
Mallet observed the resistance of chromium-iron alloys ("chromium
steels") to oxidizing agents.
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.
The invention of stainless steel followed a series of scientific
developments, starting 1798 when chromium was first shown to the
French Academy by Louis Vauquelin.
3. Austenitic Steel
This microstructure is comprehended by alloying steel with more
than sufficient nickel or manganese and nitrogen so to maintain an
austenitic microstructure at all temperatures, ranging from the
cryogenic region to the melting point. Thus, austenitic stainless
steels are not hardenable by heat treatment since they possess the
same microstructure at all temperature environments.
Austenitic stainless steel is one of the largest category of
stainless steels, making up about three-fifths of total stainless
steel production. They possess an austenitic microstructure, a
face-centered cubic crystal structure.
