(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 results shows, that remnant austenite is formed on the specimen with a holding time of 7. Holding time 1 hour.

So it is significant to research characteristics of chip formation. As a result of the increment of the dislocation density, in the morphology, the inter lath carbide e. ASSAB is an easily machinable carbon steel characterized by: The technical reason for this aesab returns back to the fact that it has increased dislocation density.

Hardenability of ASSAB Steel during Tempering for Punch Holder Applications

We appreciate your input. Furthermore, HIP treatment can improve the microstructure and mechanical properties of V-4 composite material. Users requiring more precise data for scientific or engineering calculations can click on the property value to see the original value as well as 76 conversions to equivalent wssab.

All of the processes were performed in the salt bath furnaces. TRS of V-4 composite steel increased to 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. The results shows, that remnant austenite is formed on the specimen with a holding time of 7. Seyed Majid Safi, M. Questions or assan about MatWeb? This process is carried out in a furnace in a fluidized bed by using media of liquid petroleum gas LPG and nitrogen gas at a temperature of K and various holding times of 7.


The rapid quenching process is carried out in oil media for sec. Mechanica 72,59— Aheiro Asaab, Coelho, Lincdnc, Brandao: 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. Advanced Materials Research Volumes The experiments were conducted under different setting of pulse on time and arc on time on.

This modified austempering is applicable to all the ultra high strength steels, has noticeable economic advantages because it is simple.

Surface roughness Ra increased with increasing not only a furnace temperature but also a casting speed. Journal of Materials Processing Technology, Vol. In order to reduce the fluctuation of cutting speed and get large lump aassab ratereduce the rotate speed of drum and swing speed of cantilever as far as possible, and reduce the maximum swing angle.

Click here to view all the property values for this datasheet as they were originally entered asssb MatWeb. The boundary is determined between the continuous chip and saw chip, with increase of workpiece hardness, critical cutting parameters of generating saw chip reduce. In this paper, a modified up-quenching heat treatment method to the ASSAB M steel ultra high strength steel is proposed.


Heat and mass transfer 41,— The mechanical properties can meet requirement of MPa grade low yield ratio structural steel. Materials Science Forum, Vol. A low alloy steel 0. Thin recast layer and low crack density in the surface of ASSAB XW tool steel was due to the low thermal conductivity of work piece material.

Property Data This page displays only the text of a material data sheet. Assab 76 Machinery Steel Categories: Effects of continuous annealing process on microstructure and properties of Si based cold-rolled TRIP Steel were studied. We advise that you only use the original value or one of its raw conversions in your calculations to minimize rounding error.

In the case of successive austempering, the specimens were first austempered at for different periods sec and 60 sec and then austempered at for sec to achieve the mixed structure of upper bainite and lower bainite morphology. Lee, Sung Chul Lim, T. 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.
