Hollow Rod Specialized Circular Knife For Cigarette Filter Cutting

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

Heat Treatment Of Martensitic Stainless Steels

Austenitizing, where the steel is heated to a temperature in the range 980–1,050 °C (1,800–1,920 °F), depending on grade. The resulting austenite has a face-centered cubic crystal structure.

Tempering. Martensite would be heated to around 500 °C (932 °F), held at such high temperature, then air-cooled. Higher tempering temperatures decrease yield strength and ultimate tensile strength but increase the elongation and impact resistance.

Quenching. The austenite is transformed into martensite, a hard body-centered tetragonal crystal structure. The quenched martensite is too hard and brittle for most applications. Some residual austenite may remain.

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).

Stainless Steel

Different types of stainless steel include the elements carbon (from 0.03% to greater than 1.00%), nitrogen, aluminium, silicon, sulfur, titanium, nickel, copper, selenium, niobium, and molybdenum.pecific types of stainless steel are often designated by a three-digit number, e.g., 304 stainless.

Stainless steel:276 is a family of iron-based alloys that includes approximately 11% chromium, a composition that stops the iron from rusting, while providing heat-resistant properties.
