We pride ourselves on our impeccable quality and service.

The study has shown that using of water, oil and polymer as quenchants improves the mechanical properties when compared to the untreated steels. Further though mineral oils exhibit good cooling capacity for the majority of alloy steels, they are propreties expensive and toxic. For oil-quenched specimens, a mixture of upper bainite, lower bainite and some martensite is obtained.

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.

Mategial 19 steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Home Propertids Panel Editorial Board. The heat treat temperatures were kept same for all four steels studied, as shown in Table 3. It is observed that once again the highest UTS e19 is obtained in water quenched EN 25 steel MPa which is more than twice the value MPa for the as received steel. Ramaiah Institute of Technology, Bengaluru for facilitating this research work.

After solutionizing, the samples were directly quenched in water, oil [ 9 ] or polymer solution. Home Publications Conferences Register Contact.

The standards propertues for samples to carry out the various tests are listed out in Table 2. In industry, quenching in oil or polymers is resorted to especially for heavy sections to avoid quench crack commonly observed during water quenching.


Re — Upper yield strength or R p0.

This may appear as in congruent with Figure 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 specimens quenched in poly ethylene glycol exhibited the best mechanical properties.

A set of specimens was prepared for TensileImpact, Hardness and Microstructural analyses. The microstructure of water-quenched specimens appears to be a mixture of martensite and lower bainite. It has been established that polymer can also be used as a quenching medium for MCLA forged steels.

EN9 vs EN19 Steel: What is the Difference ?

The microstructural investigation was performed using a Carl Zeiss optical microscope. Polymer quenching improves the ductility of the steel because of its lower and uniform cooling rate compared with water and oil; also there is lesser risk of cracking and distortion in the parts. J Material Sci Eng 6: DIN Materia, Alloy structural steel, we can supply the EN19 steel round bar, steel flat bar, plate, hexagonal steel bar and steel square block.

Regular size and Tolerance Round bar: The heat treated specimens had a structure of fine tempered martensite with small amount of bainite. 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.

Austenite conditioning, which depends on the prpoerties effects of alloy design and rolling techniques, is also an important factor in the grain refinement of hot-rolled steels [ 4 ].

The chemical composition of a specific steel may vary for different product thicknesses to meet mechanical property requirements. Figure 5a-5c shows the microstructures of EN 18 in the water quenched, oil quenched and polymer quenched conditions respectively. The tests were conducted using a 10 mm diameter steel ball and kg load. A standard Brinell Hardness Tester was used for measurement of indentation hardness.

Figures are plots of variations of mechanical properties when different quenchants are used. Share on Twitter Tweet. Hardness, tensile strength, Charpy impact strength and metallographic were carried out properhies the untreated and heat treated specimens.

The variation of the UTS generally follows the same behaviour as the variation of hardness. Therefore medium carbon low Alloy steels MCLA are commonly used for engineering applications in automobilesaircraft and transportation industries. Can’t read the image? Small quantities of chromium, nickel, molybdenum, copper, nitrogen, vanadium, niobium, titanium, and zirconium are used in various combinations [ 3 ].

The samples were etched with nital solution, mL ethanol and mL nitric acid for about seconds before observation in the optical microscope [ 13 – 17 ].

Flame or induction hardening eb19 give a case hardness of 50 HRC or higher. The mechanical properties of microalloyed steel result, however, from more than just the mere presence of microalloying elements. November 06, ; Accepted Date: Ann Jose ankara escort.

February 04, Citation: Variation of Elongation in Area of EN steels with as-received, quenched in water, oil and polymer. Select your language of interest to view the total content in your interested language. January 25, ; Published Date: 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.
