The effect of the production process of medium-carbon steel on fatigue strength
Journal Title: Archiwum Odlewnictwa - Year 2010, Vol 10, Issue 2
Abstract
The experimental material comprised semi-finished, high grade, medium-carbon structural steel for the production of mining chains. Steel was melted in a 140 ton electric furnace and desulfurized (E). In the second analyzed variant, steel was additionally refined with argon (EA). In the third variant, steel was melted in a 100 ton converter. Secondary treatment involved vacuum circulation degassing. Specimens with a diameter of 10 mm were prepared by hardening and tempering at 200, 300, 400, 500 and 600°C. Fatigue tests were performed with the use of a rotary bending machine at a frequency of 6000 cpm. The results were processed and presented in graphic form.
