Decoufle Nano Round Blade For Cigarette Filter Cutting Mounted In Cigarette Production Machine

Filter Knife is a component of cigarette making machines to slice filter rod after being connected to cigarette rod.

Yield Strength

Yield strength is low (200 to 300 MPa), which limits its use for structural and load-bearing components.

They are weldable by all processes; the most frequently used process is electric arc welding. They are essentially non-magnetic and maintain their ductility at cryogenic temperatures.

Their elongation is high, which allows for deformation in fabrication processes (such as deep drawing of kitchen sinks).

Austenitic Stainless Steel

Austenitic stainless steel is the largest category of stainless steels, making up about two-thirds of total stainless steel production. They possess an austenitic microstructure, a face-centered cubic crystal structure.

This micro-structure is comprehended by alloying steel with sufficient nickel or manganese and nitrogen to maintain an austenitic microstructure at all temperatures, ranging from the cryogenic region to the melting point. Thus, austenitic stainless steels are none hardenable by heat treatment since they possess the same microstructure at all temperature environments.

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.
