Heat Treatment of Cast Irons | 2018-12-12 | .

Common Heat Treatment for the Specific Cast-Iron Types. High-alloy (e.g., high chromium, high nickel-chromium) white irons can be heat treated. For example, nickel-chromium white-iron castings are given a stress-relief heat treatment because, properly made, they have an as-cast martensitic matrix structure. Tempering is performed between 205°C ...

Heat rash - Symptoms and causes - Mayo ClinicDeze pagina vertalen

Heat rash — also known as prickly heat and miliaria — isn't just for babies. It affects adults, too, especially during hot, humid weather. Heat rash develops when blocked pores (sweat ducts) trap perspiration under your skin. Symptoms range from superficial blisters to deep, red lumps. Some forms of heat rash feel prickly or intensely itchy.

Following standard heat treatment, steel grinding balls possess hardness values greater than 60 Rockwell C in the case of 3 inch diameter balls. The internal zone is also hard and therefore has low toughness, reducing the working life of the ball. The objective of the present study was to improve the quality of 3 inch diameter grinding balls by ...
