wear performance of high chromium white cast iron. Quenching, seeding and micro-alloying can, to a limited extent, increase the wear resistance, but this is best achieved by heat treatment in the solid state. The methods for producing high chrome iron casting include double pour, continuous pour and centrifugal castings [1, 3].
Heat Treatment Technology of High Chromium Iron . As an antiwear material, High Chrome White Iron Castings have not only necessary strength and toughness, but also their hardness is the most important quality index Some high chromium iron castings can obtain the required hardness in the ascast state, but most of them need heat treatment to meet the hardness …
Some high chromium iron castings can obtain the required hardness in the as-cast state, but most of them need heat treatment to meet the hardness requirements. Heat treatment is almost a necessary process for every high chromium iron casting. Reasonable quenching can make the casting obtain the best ability to resist abrasive wear.
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.
In this study, high chrome-based white cast iron (HCWCI) balls were subjected to different heat treatments to yield various amounts of retained austenite, following which they …
Pliant25 is a unique high chrome white iron that has been perfected by Penticton Foundry. Our engineered chemistry together with our proprietary heat treatment allows us to soften this alloy to the point where we can then drill and tap holes, as well as broach keyways. After machining, we can heat treat the casting to harden this alloy to a ...
