Pd 400 Acetate Tow Filter Cutter 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.
1. 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.
2. 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)
3. Martensitic Stainless Steels
They fall into four categories (with some overlap)
Martensitic stainless steels ranges from a wide variety of properties and are used as stainless engineering steels, stainless tool steels, and creep-resistant steels. They are magnetic, and are not as corrosion-resistant as ferritic and austenitic stainless steels due to their low chromium content.
