  1. 11. Heat Resistant Steel Alloys : Atlas Copco

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Malin From; Johanna Ejerhed; Artin Fattah; Markus Lindén; Alex Karlstens; [2015]
    Keywords : steel alloy heat resistant nitration;

    Abstract : Atlas Copco is interested in investigating the friction in the top-hammer drilling tool threads thatcauses the steel to heat up, leading to a phase transformation and a softer steel in the threads. Theaim of this project is to find a steel alloy or surface finishing that will retain its hardness atelevated temperatures better than the presently used threads material. READ MORE
