Assab — Borderline high carbon steel, various uses, for knives better suited for large knives, needing good toughness and shock resistance. Very low wear. Please contact us at webmaster matweb. Journal of Materials Processing Technology, Vol. Materials in World Perspective: Gas cementation is a heat treatment surface process by means of carbon diffusing into steel. The experimental verification indicates that the simulation results agree well with the experimental ones. Aheiro Reginalot, Coelho, Lincdnc, Brandao: ASSAB is an easily machinable carbon steel characterized by: Additionally, this gas cementation process when followed by the quenching process is effective in forming the martensite and austenite microstructures.

The microstructures are ferrite, bainite and retained austenite and the volume fraction of retained austenite for the tested steel is 9. The rapid quenching process is carried out in oil media for sec. Good machinability Good mechanical strength. The technical reason for this superiority returns back to the fact that it has increased dislocation density. Additionally, this gas cementation process when followed by the quenching process is effective in forming the martensite and austenite microstructures.

Use of this modified austempering for heavy parts, leads to the lightness of heavy parts and combination of the thermomechanical methods with this modified austempering can yield even much more improvements.

Thin recast layer and low crack density in the surface of ASSAB XW tool steel was due to the low thermal conductivity work piece material. In order to reduce the fluctuation of cutting speed and get large lump coal ratereduce the rotate speed of drum zssab swing speed of cantilever as far as possible, and reduce the maximum swing angle.

In order to remove the tension in the specimen, the tempering process is carried out in a furnace at a low temperature of K with holding time of 3. With the increase of depth of cut, the tool-workpiece temperature recorded an increment between to 65oC for both continuous and interrupted cutting. Furthermore, HIP treatment can improve the microstructure and mechanical properties of V-4 composite material. So it is to research characteristics of chip formation.

Data sheets for overmetals, plastics, ceramics, and composites. As well, it is shown that the best combination of strength and ductility can be achieved by the proposed heat treatment method. Alumina Al 2 O 3 Nanofibers from Electrospinning p. Generally, as the cutting speed, feed rate and depth of cut increases, the tool-workpiece temperature for both continuous and interrupted cutting will increase.

A low alloy steel 0. The mechanical properties can meet requirement of MPa grade low yield ratio assxb steel. Experimental results showed that the microstructure of matrix had small needle structures after HIP treatment, which were effective in improving the hardness and strength.
