Skoda Protos Machine Cigarette Rod Cutting Blade Mounted After Cigarette Wrapping Process

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

Usages

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

Automobile exhaust pipes (Type 409 and 409 Cb[2] are used in North America; stabilized grades Type 439 and 441 are used in Europe)

Architectural and structural applications (Type 430, which contains 17% Cr)

Household goods, such as kitchenware, sinks, and major appliances

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)

Ferritic Stainless Steels

Ferritic stainless steels possess a ferrite microstructure like carbon steel, which is a body-centered cubic crystal structure, and contain between 10.5% and 27% chromium with very little or no nickel. This microstructure is present at all temperatures due to the chromium addition, so they are not hardenable by heat treatment. They cannot be strengthened by cold work to the same degree as austenitic stainless steels. They are magnetic.

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]
