Nitrogen - Alloyed Martensitic Decoufle Nano Filter Cutter

Decoufle Nano 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.

Nitrogen-Alloyed Martensitic Stainless Steels

Replacing some carbon in martensitic stainless steels by nitrogen is a just recent development. The limited solubility of nitrogen would be increased by the pressure electroslag refining process, in which melting is carried out under nitrogen pressure. Steel containing up to 0.41% nitrogen is achieved, leading to higher hardness and strength and higher corrosion resistance. As PESR is expensive, lower but significant nitrogen contents have been achieved by using the standard argon oxygen decarburization process.

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.

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.
