Decoufle Nano Circular Knife For Cigarette Filter Cutting

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.
