(Assab) – Borderline high carbon steel, various uses, for knives better suited for large knives, needing good toughness and shock resistance. Very low wear. The purpose of this research was to evaluate the hardenability of ASSAB ( equivalent to AISI and JIS S45C) steel subjected to the gas. This paper describes the optimisation of the processing parameters for maximum hardened depth of ASSAB (equivalent to AISI ) steel specimens of.

The rapid quenching process is carried out in oil media for sec. Precision Hard Cutting process is easy to generate periodic saw chip. Materials Science Forum Volume Aheiro Reginalot, Coelho, Lincdnc, Brandao: The specimens selected for up-quenching, after austenitization were quenched to below for sec.

Hardenability of ASSAB Steel during Tempering for Punch Holder Applications

And performance indexes can meet the requirement of MPa grade low yield ratio structural steel. Metal ; Ferrous Metal ; Carbon Steel. Please read our License Agreement regarding materials data and our Privacy Policy. The experimental verification indicates that the simulation results agree well with the experimental ones. Experimental results showed that the microstructure of matrix had zssab needle structures after HIP treatment, which were assan in improving the hardness and strength.


The results shows, that remnant austenite is formed on the specimen with a holding time of 7. 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.

Additionally, this gas cementation process when followed by the aesab process is effective in forming the martensite and austenite microstructures.

Generally, as the cutting speed, feed rate and depth of cut increases, the tool-workpiece temperature for both continuous and interrupted cutting will increase. Assb result shows that, the Vickers hardness values can be achieved from to HV. Based on improved Maynier model of steel chemical composition and cooling rate, the microstructure constituents and hardness of 30mm thickness pressure vessel steel 07MnNiMoVDR are predicted and calculated with interpolation method.

TRS of V-4 composite steel increased to Alumina Al 2 O 3 Nanofibers from Electrospinning p. As a result of the increment of the dislocation density, in the morphology, the inter lath carbide e.

Azsab cementation is a heat treatment surface process by means of carbon diffusing into steel. A low alloy steel 0. Modulus of Elasticity, HB.

So it is significant to research characteristics of chip formation. Surface roughness Ra increased with increasing not only a furnace temperature but also a casting speed. Experimental results showed that the TRS of original V-4 steel powder was The rapid quenching process is carried out in an oil media for sec.


It has been shown that the mixed structure of tempered martensite and lower bainite that has been suggested in this investigation offers a good combination of strength and ductility. Surface and Coatings Technology, Vol. Finite difference equations are used for simulation of plate temperature field in roller quenching, and cooling rate in thickness direction is calculated in this paper.

Therefore, qssab is confirmed that by using these processes, the hardening of ASSAB steel can be carried out and the punch holder can be manufactured.

This process is carried out in a furnace in a fluidized bed by using media of liquid petroleum gas LPG 7760 nitrogen gas at a temperature of K and various holding times of 7. It is only to be heat treated for special applications. ASSAB is an easily machinable carbon steel characterized by: Journal of Materials Processing Technology, Vol. 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.
