Hardenability of ASSAB 760 Steel during Tempering for Punch Holder Applications

Mechanica 72,59— In the case of successive austempering, the specimens were first austempered at for different periods asssab and 60 sec and then austempered at for sec to achieve the mixed structure of upper bainite and lower bainite morphology. The mechanical properties can meet requirement of MPa grade low yield ratio structural steel. Or if you don’t have an account with us yet, then click here to register.

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.

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. ASSAB is an easily machinable carbon steel characterized by: As a result of the increment of the dislocation density, in the morphology, the inter asxab carbide e.

So it is significant to research characteristics of chip formation.

The Index of Temperature Fluctuation ITF was proposed to predict the effect of temperature fluctuation on the formation of billet surface defects. The rapid quenching process is carried out in oil media for sec. Heat and mass transfer 41,— Based on Xssab 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.

The microstructures are ferrite, bainite and retained austenite and the volume fraction of retained austenite for the tested steel is 9.

Lee, Sung Chul Lim, T. Based on improved Maynier model of steel chemical composition and cooling rate, asxab microstructure constituents and hardness of 30mm thickness pressure vessel steel 07MnNiMoVDR are predicted and calculated with interpolation method.

In this paper, a modified up-quenching heat treatment method to the ASSAB M steel ultra high strength steel is proposed.

As well, it is shown that the best combination of strength and ductility can be achieved by the proposed heat treatment method. Experimental results showed that the microstructure of matrix had small needle structures after HIP treatment, which were effective in improving the hardness and strength. aswab

Seyed Majid Safi, M. Experimental results showed that the TRS of original V-4 steel powder was And performance indexes can meet the requirement of MPa grade low yield ratio structural steel.

This paper present the tool-workpiece temperature result recorded by thermal imaging camera with various cutting parameter applied. Generally, as the cutting speed, feed rate and depth of cut increases, the tool-workpiece temperature for both continuous and interrupted cutting will increase.

It can be concluded that surface roughness, recast layer thickness and density of microcracks increased proportionally with pulse on time and arc on time.
