Jan 13, 2016· 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.
Cr initiate formation of an oxide-impenetrable layer on the surface of cast pieces, which adhere very well to the metal. Due to this, chrome irons are resistant to the action of heat and various corroding media7. Above 16 per cent Cr, an oxide layer type FcO.Cr20, forms on the iron surface, which strongly increases
