Decoufle Cut Off Knife For Cutting Process After Garniture Assembly Of Making Machine Of Filter Cigarette

Cigarette Knife is a component of cigarette making machines to slice cigarette rod before going into the filter assembly machine.

Yield Strength

Yield strength is low (200 to 300 MPa), which limits their use for structural and other load-bearing components. Their elongation is high, which allows for deformation in fabrication processes (such as deep drawing of kitchen sinks).[citation needed] They are weldable by all processes; the most frequently used process is electric arc welding (see welding section below).[citation needed] They are essentially non-magnetic and maintain their ductility at cryogenic temperatures.[citation needed]

Austenitic Stainless Steel

Austenitic stainless steel is the largest family of stainless steels, making up about two-thirds of all stainless steel production. They possess an austenitic microstructure, which is a face-centered cubic crystal structure. This microstructure is achieved by alloying steel with sufficient nickel and/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 not hardenable by heat treatment since they possess the same microstructure at all temperatures.

Invention

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. 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.
