Abstract. Objectives: The aim of the study was to measure the dermal exposure levels of chromium dust during grinding of stainless and acid-proof steel parts.Methods: The potential dermal exposure of the body was measured with a patch sampling method and the actual exposure of hands with a hand-wash method. Simultaneously, personal air samples were also collected.The invention discloses an ultrahigh chromium grinding ball and a processing process of the ultrahigh chromium grinding ball. A metal material which is appropriate in chromium content and low in carbon content is selected to ensure the chromium-carbon ratio to be about 7-10, so as to obtain metallographic structures of martensite (M), alloy carbon compound (M7C3) and residual austenite (A ...
