Alloy data sheet high chrome white iron 25% | Penticton

Jan 13, 2016· ASTM A532 Class III Type A. The 25% Cr alloy is the most common high chrome white iron poured at Penticton Foundry. This alloy has great abrasion resistant properties especially against gouging, grinding and scratching. 25% Cr material can be machined to meet tighter tolerances like those found in pump and piping type castings.

Heat treatment process for high chromium grinding ball

Heat treatment of high chromium grinding ball is the main method to obtain good wear resistance. The research on high chromium cast iron ball mainly focuses on chemical composition selection, heat treatment process determination, modifier selection, good carbide type and wear mechanism.

Heat treatment process of the high chrome cast iron

The microstructure of high chromium white cast iron grinding ball as-cast and after heat treatment was observed by metallographic microscope. The sample of 10mm* 10 mm* 8 mm in size at the center of the grinding ball was cut by weld and polished with 200 # to 1500 # metallographic sandpaper.

Heat Treating of High-Alloy White Irons :: Total Materia

An austenitizing heat treatment usually comprised heating at temperatures between 750 and 790°C (1380 and 1450°F) with a soak time of 8 h. Air or furnace cooling, not over 30°C/h, was conducted followed by a tempering/stress-relief heat treatment. Refrigeration heat treatment is the more commonly practiced remedy for low hardness today.

Heat Treatment of Cast Irons | 2018-12-12 | Industrial Heating

Dec 12, 2018· 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.
