MARK9 Of Molins Final Cut Blade With Filters Assembled By Cigarette
Making Line
Filter Knife is a component of cigarette making machines to slice
filter rod after being connected to cigarette rod.
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 resistance against
attack by some acids and suggested their use in cutlery.
The invention of stainless steel followed a series of scientific
developments, starting in 1798 when chromium was first shown to the
French Academy
In the early 1800s, James Stodart, Michael Faraday, and Robert
Mallet observed the resistance of chromium-iron alloys ("chromium
steels") to oxidizing agents.
Yield Strength
Yield strength is low (200 to 300 MPa), which limits its use for
structural and load-bearing components.
Their elongation is high, which allows for deformation in
fabrication processes (such as deep drawing of kitchen sinks).
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.
Usages
Ferritic stainless steels are cheaper than austenitic steels and
present in many commercial products, which include:
Architectural and structural applications (Type 430, which contains
17% Cr)
Household goods, such as kitchenware, sinks, and major appliances
Automobile exhaust pipes (Type 409 and 409 Cb[2] are used in North
America; stabilized grades Type 439 and 441 are used in Europe)
Building components, such as slate hooks, roofing, and chimney
ducts
Power plates in solid oxide fuel cells operating at temperatures
around 700 °C (1,292 °F) (high-chromium ferritics containing 22%
Cr)
