ASSAB 760 PDF

The Index of Temperature Fluctuation ITF was proposed to predict the effect of temperature fluctuation on the formation of billet surface defects. 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. 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. Please contact us at webmaster matweb.

The results shows, that remnant austenite is formed on the specimen with a holding time of 7. The rapid quenching process is carried out in an oil media for sec. Temperature generated on the tool-workpiece has significant effect on the cutting performance. This modified austempering is applicable to all the ultra high strength steels, has noticeable economic advantages because it is simple. Experimental results showed that the microstructure of matrix had small needle structures after HIP treatment, which were effective in improving the assa and strength.

ASSAB is an easily machinable carbon steel characterized by: Gas cementation is a heat treatment surface process by means of carbon diffusing into steel. Good machinability Good mechanical strength. Generally, as the cutting speed, feed rate and depth of cut increases, the tool-workpiece temperature for both continuous and interrupted cutting will increase.

Equivalent chart Use of this modified austempering for heavy parts, leads to the lightness of heavy parts and combination of the thermomechanical assag with this modified austempering can yield even much more improvements. Assab Steels Machinery Steel Categories: And performance indexes can meet the requirement of MPa grade low yield ratio structural steel. Gas cementation is a heat treatment surface process by means of awsab diffusing into steel. Experimental results are presented and the advantages of the modified method are discussed.

Holding time 1 hour. Precision Hard Cutting process is easy to generate periodic saw chip. Tensile Strength, Yield, R p Users requiring precise data for scientific asswb engineering calculations can click on the property value to see the original value as well as raw conversions to equivalent units.

With the increase of depth of cut, the tool-workpiece temperature recorded an increment between 50oC to 65oC for both continuous and interrupted cutting. Click here to view all the property values for this datasheet as they were originally entered into MatWeb.

Questions or comments about MatWeb? Furthermore, HIP treatment can improve the microstructure and mechanical properties of V-4 composite material. MatWeb is intended for personal, non-commercial use. The boundary is determined between the continuous chip and saw chip, with increase of workpiece hardness, critical cutting parameters of generating saw chip reduce.

Cu-Be alloy C rod having diameter of Beside, the hardness increased to HRA As well, it is shown that the best combination of strength and ductility can be achieved by the proposed heat treatment method. The results asdab that the low ratio and high strength can be obtained by proper phase compositions including relative soft phase and hard phase.

The Index of Temperature Fluctuation ITF was proposed to predict the effect of temperature fluctuation on the formation of billet surface asssab. 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 mechanical properties can meet requirement of MPa grade low yield ratio structural steel. Surface and Coatings Technology, Vol. The results can provide a reasonable amount of reference data for choosing cutting parameters of high-speed hard cutting. The result shows that, the Vickers hardness values can be achieved from to HV. Tensile Strength, Ultimate, Rm. Additionally, this gas cementation process when followed by the quenching process is effective in forming the martensite and austenite microstructures.

This paper present the tool-workpiece temperature result recorded by thermal imaging camera with various cutting parameter applied. The rapid quenching process is carried out in oil media for sec. Please contact us at webmaster matweb. Kim, Hyouk Chon Kwon, W. Review of the Research on Evaluation of Livable City p.

Journal of Materials Processing Technology, Vol. The results shows, that remnant austenite is formed on the specimen with a holding time aswab 7. The aesab verification indicates that the simulation results agree well with the experimental ones.

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 asdab 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.

Diploma thesis, UPT. Perpustakaan Unand. Sesuai dengan sifatnya baja ini cukup tangguh namun masih kurang baik untuk diaplikasikan pada komponen yang bergesek. Oleh karena itu, dilakukan usaha meningkatkan kekerasan permukaan baja ASSAB tanpa menghilangkan sifat tangguhnya tahan terhadap penjalaran retak. Salah satu usaha peningkatan kekerasan permukaan ini dilakukan dengan proses pack carburizing. Saat ini proses pack carburizing masih berkembang, terutama pada media-media yang digunakan.
