Wear and Friction Evaluation of Different Tool Steels for

The aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a 22MnB5 uncoated steel at elevated temperatures were investigated using a high-temperature version of the Optimol SRV reciprocating friction and wear tester at temperatures of ...

Corrosion Behaviour of Type 316L Stainless Steel in Hot

Oct 20, 2019 The corrosion behaviour of type 316L stainless steel in aqueous 3050 wt. NaOH at temperatures up to 90 C has been elucidated. Exposure to room temperature environment showed parabolic weight loss behaviour, with corrosion rates of up to 0.4 mmyear. Higher NaOH concentrations and exposure temperatures resulted in a reduced stability of the electrochemical passivity domain,

Optimization of mill performance by using

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
