Skoda 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.
1. Stainless Steel
Stainless steel:276 is a family of iron-based alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting,as well as providing heat-resistant properties.Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminium, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum.pecific types of stainless steel are often designated by a three-digit number, e.g., 304 stainless.
2. Resistance To Ferric Oxide Formation
Stainless steel's resistance to ferric oxide formation results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack, and can self-heal in the presence of oxygen. Corrosion resistance can be increased further, by:
increasing the chromium content to levels above 11%;
addition of 8% or higher amounts of nickel
addition of molybdenum (which also improves resistance to "pitting corrosion")
3. 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.
