Particle Erosion of SUS403 Tempered Martensitic Stainless Steel

Abstract

The particle erosion behavior of SUS403 martensitic stainless steel tempered with five different temperatures range from 200 to 600°C were studied as a function of impact angle and hardness. The results indicate that the dominated mechanisms for material removal are cutting and extrusion at low and high impact angles, respectively. A transition of mechanism mixed by cutting and extrusion occurs at medium impact angle. Grain boundary cracking is often found for all impact angles that seem to be one of the major erosion mechanisms for two-phase materials mixed with martensite and ferrite. The erosion rate of all the experimental materials increases first, and then decreases with increase in impact angle. Thus, the maximum erosion rate occurs at the angle between 30°and 45°. At 15°and 30°of impingement, the erosion rate is virtually independent of hardness. While impact angles exceed than 30°, erosion rate increases with increasing hardness.

Improvement of slurry erosion resistance of martensite/ferrite duplex stainless steel by hot rolling

“…These changes can refine the grain size of the metals and alter their final microstructure and mechanical properties [9]. Many aspects of the erosion of stainless steels have been studied [10][11][12][13][14][15]. However, reports that focus on the slurry erosion behavior of M/Fss are rare, especially regarding M/ Fss grains that are refined by hot rolling.…”

Slurry Erosion Response of Heat Treated 13Cr-4Ni Martensitic Stainless Steel

“…Finnie et al [8] have reported material loss is maximized when the angle of impingement is approximately 30° for ductile and 90° for brittle materials. Ductile materials damages are mainly through cutting mechanism at a low impact angle during erosion [9]. On the other hand, the erosion damage of brittle materials is based on fracture and occurs at an impact angle close to 90°.…”
