It is observed that the maximum hardness value of BHN is prkperties in EN 25 with water quenching in general, water quenching has the maximum impact on hardness followed by oil quenching and polymer quenching as the least defect [ 10 – 12 ].
The steels in sheet or plate form have low proprrties content 0. The standards used for samples to carry out the various tests are listed out in Table 2. Hardness, tensile strength, Charpy impact strength and metallographic were carried out on the untreated and heat treated specimens.
The authors are thankful to the management of M. The samples were etched with nital solution, mL ethanol and mL nitric acid for about seconds before observation in the optical microscope [ 13 – 17 ]. We pride ourselves on our impeccable quality and service.

EN 19 steel Annealing delivery hardenss less than HB. The chemical composition of a specific steel may vary for different product thicknesses to meet mechanical property requirements. Materiak questions will be reply in 24 hours.
Impact energy to failure was found using a Charpy impact tester. EN19 alloy structure Steel heat treatment A. Figures are plots of variations of mechanical properties when different quenchants are used. The synthetic polymer quenchant, polyethylene glycol PEG [ 2 ] has the advantages of lesser risk of cracking and less distortion, resulting in better mechanical properties compared to water, oil and brine solutions. EN 19 steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes.
Share on Google Plus Share. The mechanical properties of microalloyed steels result, however, from more than just the mere presence of microalloying elements. Shows the Mechanical properties of as-received and quenched steel samples. Research Article Open Access.
EN19 is a high quality alloy steel with tensile strength. Home Publications Conferences Register Contact. Small quantities of chromium, nickel, molybdenum, copper, nitrogen, vanadium, niobium, titanium, and zirconium are used in various combinations [ 3 ]. Ramaiah Institute of Technology, Bengaluru for facilitating this research work.
We have thirty power saws available throughout the Smiths Group including a fully automated magazine feed CNC rod blanking line. Therefore medium carbon low Alloy steels MCLA are commonly used for engineering applications in automobilesaircraft and transportation industries. The quenched samples were thereafter tested for their mechanical properties. November 06, ; Accepted Date: The alloy offers good wear resistance too and can be case hardened. Of the conventional quenching media, water, oil and polymerwater quenching and in some cases even oil quenching may result in quench cracks in thick sections.
The microstructural investigation was performed using a Carl Zeiss optical microscope.

The uniform low cooling rates also result in better mechanical properties for the polymer quenched steels. Medium carbon low alloy forged steels EN 18, EN19, EN 24, and EN25 have been investigated with respect to their mechanical properties after heat treatment. In industry, quenching matdrial oil or polymers is resorted to especially for heavy sections to avoid quench crack commonly observed during water quenching.
They are not considered to be alloy steels in the normal sense because they are designed to meet specific mechanical properties rather than a chemical composition steels have yield strengths greater than MPa, or 40 ksi.
It has been established that polymer can also be used as a quenching medium for MCLA forged steels. This may appear as in congruent with Propertles 4 where the percentage of elongation of the forged steels is highest in the as received condition in the lower in the heat treated conditions except for oil quenching.
The mechanical properties of microalloyed steel result, however, from more than just the mere presence of microalloying elements. Engineering Alloy Steel material EN19 yield strength: J Material Sci Eng 6: We believe this underlines our total commitment to quality and our ethos of being the complete service propeeties.

Our staff are ready to take your call. The present study is aimed at determining a comparative evaluation of mechanical properties mategial in MCLA steels EN steels properfies different quenching media with standard step tempering procedure [ 5 – 8 ]. The microstructure of water-quenched specimens appears to be a mixture of martensite and lower bainite. The study has shown that using of water, oil and polymer as quenchants improves the mechanical properties when compared to the untreated steels.
