The steels in sheet or plate form have low carbon content 0. Austenite conditioning, which depends on the complex effects of alloy design and rolling techniques, is also an important factor in the grain refinement of hot-rolled steels.

The mechanical properties of microalloyed steel result, however, mzterial more than just the mere presence of microalloying elements. January 25, ; Published Date: ASTM EN 19 steel is a alloy structural steel, EN 19 is used for engineering structural, use in Machine tool and automotive industries gear, gears, shafts, spindles, gears, bolts, studs and a wide variety of applications where a good quality high tensile steel grade is suited.
Medium carbon low alloy forged steels EN 18, EN19, EN 24, and EN25 have been investigated with respect to propertied mechanical properties after heat treatment. Guidelines Upcoming Special Issues.
The variation of the UTS generally follows the same behaviour as the variation of hardness. The heat treat temperatures were kept same for all four steels studied, as shown in Table 3. The standards used for samples to carry out the various tests are listed out in Table 2.
A set of specimens was prepared for TensileImpact, Hardness and Microstructural analyses.
EN19 Steel Plate
Figures are plots of variations of mechanical properties matefial different quenchants are used. Once again it is evident that step tempering after quenching for hardening has improved impact energy of steels except in case of water quenching of EN18 and EN The chemical composition of a specific steel may vary for different product thicknesses to meet mechanical property requirements.
Research Article Open Access. Impact energy to failure was found using a Charpy impact tester. It is observed that the maximum hardness value of BHN is obtained in EN 25 with water quenching in general, water quenching has the maximum impact on hardness followed by oil properhies and polymer quenching as the least defect [ 10 – 12 ].
Table 4 shows the mechanical properties of the as—received and heat treated steel samples with the three quenchants. The specimens quenched in poly ethylene glycol exhibited the best mechanical properties. Matsrial samples were etched with nital solution, mL ethanol and mL materoal acid for about seconds before observation in the optical microscope [ 13 – 17 ].

November 06, ; Accepted Date: Therefore medium carbon low Alloy steels MCLA are commonly used for engineering applications in automobilesaircraft and transportation industries. The uses of medium carbon steels include shafts, axles, gears, crankshafts, couplings and forgings. Home Editorial Panel Editorial Board. Re — Upper yield strength or R p0. Variation of Elongation in Area of EN steels with as-received, quenched in water, oil and polymer.

For oil-quenched specimens, a mixture of upper mxterial, lower bainite and some martensite is obtained. It has been established that polymer can also be used as a quenching medium for MCLA forged steels. Figure 1 shows the variation of hardness for the four EN steels when the quenchant is changed from water to oil and then polymer.
The microstructure of water-quenched specimens appears to be a mixture of martensite and lower bainite.
Grain refinement by austenite conditioning with controlled rolling methods has resulted in improved toughness and high yield strengths in the range of to MPa 50 to 90 ksi. Variation of Impact Energy of EN steels with as-received, quenched in water, oil and polymer.
The tests were conducted using a 10 mm diameter steel ball and kg load. Figure 3 depicts the change of impact energy of the four EN steels considered. Share on Pinterest Share. Polymer quenching improves the ductility of the steel because of its lower and uniform cooling rate compared prooerties water and oil; also there is lesser risk of cracking and distortion in the parts.

Applications ASTM EN 19 steel is a poperties structural steel, EN 19 is used for engineering structural, use in Machine tool and automotive industries gear, gears, shafts, spindles, gears, bolts, studs and a wide variety of applications where a good quality high tensile steel grade is suited 6.
EN9 vs EN19 Steel: What is the Difference ?
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. Propertie many huge merger deals in the industry, we remain a friendly, family business. We pride ourselves on our impeccable quality and service.
The quenched samples were thereafter tested for their mechanical properties.
