120mm Uncut Rods Final Cut Knife Of Cigarette Assembly Line For Last Cutting Process Of Filters

Filter Knife is a component of cigarette making machines to slice filter rod after being connected to cigarette rod.

1. Ferritic Steels

This micro-structure is presented at all temperatures due to the chromium addition, thus they are not hardened by heat treatment. They can never be strengthened by cold work to the same degree as austenitic stainless steels.

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

2. Product Usages

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

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

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)

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

3. Martensitic Steels

They all fall into four categories (with some overlap though)

Martensitic stainless steels ranges from a large variety of properties and are used as stainless engineering steels, stainless tool steels, and creep-resistant steels. They are all magnetic, but not as corrosion-resistant as ferritic and austenitic stainless steels because of their low chromium content.
