Hollow Rod Specialized 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.

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)

Ferritic Stainless Steels

Ferritic stainless steels possess a ferrite micro-structure like carbon steel, which is a body-centered cubic crystal structure, and contain between 10.6% and 27.2% chromium with very little or no nickel. They are magnetic.

This micro-structure is present at all temperatures due to the chromium addition, so they are not hardened by heat treatment. They cannot be strengthened by cold work to the same degree as austenitic stainless steels.

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).
