Figure 5a-5c shows the microstructures of EN 18 in the water quenched, oil quenched and polymer quenched conditions respectively. It is observed that once again the highest UTS value is obtained in water quenched EN 25 steel MPa which is more than twice propedties value MPa for the as received steel.

The microstructural investigation was performed using a Carl Zeiss optical microscope. Bespoke Supply Overview How it Works?

We believe this underlines our total commitment to quality and our ethos of being the complete service provider. Can’t read the image? 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.

For oil-quenched specimens, a mixture of upper bainite, lower bainite and some martensite is obtained. We pride ourselves on our materiaal quality and service.

EN19 is a high quality alloy steel with tensile strength. About Our Company Otai Special Steel was established in to provide a wide range of high quality steel to the global market. The microstructure of water-quenched specimens appears to be a mixture of martensite and lower bainite. The variation of the UTS generally follows the same behaviour as the variation of hardness.

EN9 vs EN19 Steel: What is the Difference ?

The uniform low cooling rates also result in better mechanical properties for the polymer quenched steels. The samples were etched with nital solution, mL ethanol and mL nitric acid for about seconds before observation in the optical microscope [ 13 – 17 ].

Thus polymer quenching would improve ductilitytoughness and impact strength values. Impact energy to failure was found using a Charpy peoperties tester. In sequence, the steps include sectioning, mounting, coarse grinding, fine grinding, polishing, etching and microscopic examination, and the general procedure followed by earlier investigators was employed [ 6 ].

J Material Sci Eng 6: 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.
