Decoufle Nano Final Cut Blade To Cut Cigarette Rod 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 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.

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).

Usages

Ferritic stainless steels are cheaper than austenitic steels and present in many commercial products, which include:

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)

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)
