In case of polymer quenched steels, the microstructure consists of fine tempered martensite with a small amount of ferrite. The uniform low cooling rates also result in better mechanical properties for the polymer quenched steels.

Maferial on Google Plus Share. 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 quenched samples were thereafter tested for their mechanical properties. Share on Pinterest Share. Figure 1 shows the variation of hardness for the four EN steels when the quenchant is changed from water to oil and then polymer. 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.

Thus polymer quenching would improve ductilitytoughness and impact strength values. The mechanical properties of microalloyed steel result, however, from more than just the mere presence of microalloying elements.

February 04, Citation: It has been established that polymer can also be used as a quenching medium for MCLA forged steels. Bespoke Supply Overview How it Works?


Variation of Impact Energy of EN steels with as-received, quenched in water, oil and polymer.

EN9 vs EN19 Steel: What is the Difference ?

The present study is aimed at determining a comparative evaluation of mechanical properties achieved in MCLA steels EN steels with different quenching media with standard step tempering procedure [ 5 – 8 ].

Customer Benefits Real World Examples. Agri and Aquaculture Journals Dr. Research Article Open Access. EN19 alloy structure Steel heat treatment A. The microstructure of water-quenched specimens appears to be a mixture of martensite and lower bainite. Variation of Elongation in Area of EN steels with as-received, quenched in water, oil and polymer. Regular size and Tolerance Round bar: Figures are plots of variations of mechanical properties when different quenchants are used.

Despite many huge merger deals in the industry, we remain a friendly, family business. EN19 Steel 1. Thereafter quenching was carried out in three media, viz. EN19 Engineering Steel is a high tensile steel with good ductility and shock resistance. Share on LinkedIn Share.

Flame or induction hardening can give a case hardness of 50 HRC or higher. Guidelines Upcoming Special Issues. A set of specimens was prepared for TensileImpact, Hardness and Microstructural analyses.

EN19 Steel | 4140 | 1.7225 | SCM440 | 42CrMo4

For oil-quenched specimens, a mixture of upper bainite, lower bainite and some martensite is obtained. 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. Small quantities of chromium, nickel, molybdenum, copper, nitrogen, vanadium, niobium, titanium, and zirconium are used in various combinations [ 3 ].

About Our Company Otai Special Steel was established in propertoes provide a wide range of high quality steel to the global market. January 25, ; Published Date: Mxterial heat treat temperatures were kept same for all four steels studied, as shown in Table 3. ASTM EN 19 steel is properyies 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.


EN19 is a high quality alloy steel with tensile strength. Ramaiah Institute of Technology, Bengaluru for facilitating matefial research work. Shows the Mechanical properties of as-received and quenched steel samples. The tensile tests were carried out using an electrically powered Hounsfield tensometer with a capacity of 20 KN.

The variation of the UTS generally follows the same behaviour as the variation of hardness. The steels in sheet or plate form have low carbon content 0. Our staff are ej19 to take your call. 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.

The chemical composition of a specific steel may vary for different product thicknesses to meet mechanical property requirements.
