(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.

Experimental results showed that the TRS of original V-4 steel powder was So it is significant to research characteristics of chip formation.
Questions or comments about MatWeb? We appreciate your input. Materials Science Forum Volume Journal of Magnetism and Magnetic Materials, Vol. Thin recast layer and low crack density in the surface of ASSAB XW tool steel was due 70 the low thermal conductivity of work piece material.
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.
Assab Knife Steel Composition Analysis Graph, Equivalents And Overview Version
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.
Alumina Al 2 O 3 Nanofibers from Electrospinning p.
xssab The experimental verification indicates that the simulation results agree well with the experimental ones. Therefore, it is confirmed that by using these processes, the hardening of ASSAB steel can be carried out and the punch holder can be manufactured.
This modified austempering is applicable to all the ultra high strength steels, has noticeable economic advantages because it is simple.
Hardenability of ASSAB 760 Steel during Tempering for Punch Holder Applications
Journal of Materials Processing Technology, Vol. Effects of continuous annealing process on microstructure and properties of Si based cold-rolled TRIP Steel were studied. With the increase of depth of cut, the tool-workpiece temperature recorded an increment between 50oC to 65oC for both continuous and interrupted cutting.
Journal of Materials Processing Technology, Vol. 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. The results showed that the low yield ratio and high strength can be obtained by 706 phase compositions including relative soft phase and hard phase.
As a result of the increment of the dislocation density, in the morphology, the inter lath carbide e. Generally, as the cutting speed, feed rate and depth of cut increases, the tool-workpiece temperature for both continuous and interrupted cutting will increase.
Review of the Research on Evaluation of Livable City p. Beside, the hardness increased to HRA The contents, results, and technical data from this site may not be reproduced either electronically, photographically or substantively without permission from MatWeb, LLC. Experimental results are presented and the advantages of the modified method are discussed.
It can be concluded that surface roughness, recast layer thickness and density of microcracks increased proportionally with pulse on time and arc on time.
The specimens selected for up-quenching, after austenitization were quenched to below for sec. Mechanica 72,59— The microstructures are ferrite, bainite and retained austenite and the volume fraction of retained austenite for the tested steel is 9.
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. 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. The Index of Temperature Fluctuation ITF was proposed to predict the effect of temperature fluctuation on the formation of billet surface defects.
Precision Hard Cutting process is easy to generate periodic saw chip. The effect of different continuous casting parameters on temperature fluctuation were analyzed, and the temperature fluctuation was considered to be a key factor to the formation of oscillation marks.

aassab The rapid quenching process is carried out in oil media for sec. The results can provide a reasonable amount of reference data for choosing cutting parameters of high-speed hard cutting.
Based on DEFORM software platform and FEM, the behavior of adiabatic shear in cutting deformation zone is simulated, simulation results show that the formation of saw chip is due to plastic instability occurred in the shear plane resulting concentrated shear slip; chip cross-sectional microscopic analysis is used to analyzed chip morphology, microscopic observation results show that with the increase of cutting parameters, the degree of segmentation increases and the cutting speed is the most significant factor.
Modulus of Elasticity, HB. Or if you don’t have an account with us yet, then click here to register. The result shows that, the Vickers hardness values can be achieved from to HV. Tensile Strength, Ultimate, Rm. MatWeb is intended for personal, non-commercial use. Surface and Coatings Technology, Vol. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.
Holding time 1 hour. Materials in World Perspective: The results shows, that remnant austenite is formed on the specimen with a holding time of 7. The result shows that, the Vickers hardness values can be achieved from to HV. Therefore, it is confirmed that by using these processes, the hardening of ASSAB steel can be carried out and the punch holder can be manufactured. Seyed Majid Safi, M.
