Abstract

Abstract : Herein this investigation, profiled high interstitial austenitic stainless steel parts are burnished on a profile‐rolling machine, and afterward, the wear behavior is analyzed in a melt of glass‐reinforced polypropylene. Wear and corrosion resistance are significant properties of steel parts in the plastics and food industries. The high work‐hardening ability of high interstitial austenitic stainless steel enables burnishing parts with a significant local hardness to increase up to maximum values of ≈600 HV 1. Wear tests on a recently developed test stand reveal that the burnished austenitic stainless steel surface performs similarly to a nitrided surface of the standard nitriding steel 31CrMoV9 + QT with a hardness of ≈830 HV 0.5. Regarding the given advantage of corrosion resistance, it is concluded that roller burnishing supports the applicability of high interstitial austenitic stainless steel in plastics and food industries. Abstract : Herein, it is shown that roller burnishing of high interstitial austenitic stainless steel parts results in high material hardness without the need for subsequent heat treatment and fine processing. A test stand is developed to simulate wear conditions in a plastics extruder. Wear is analyzed on the profiled geometry.
