Jan 26, 2016· Pliant25 ASTM A532 Class III Type A. 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 minimum of .
Jan 05, 2017· High Chromium cast iron,as one common materials in industry field,Halnn as the leader of cbn inserts and pcd cutting tools in China, we have researched new .
Highchromium irons have good mechanical properties, high hardness in a cast state, low fluctuation of hardness when properties change. Highchromium irons almost don''t concede in fluidity to regular gray cast iron that allows using parts sufficiently difficult form directly after casting without the following machining.
bertin and Sinatora [9] tested cast iron balls produced from Fe(12 to 25)Cr( to )C with carbide fractions of 13 to 40% by wet, ball milling with hematite (400600 HV), phosphate rock (about 300 HV) or quartz sand (about 1000 HV) as abrasives and noted that the effect of carbide volume fraction on the wear resistance of high chromium cast
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.
Highchromium white cast iron characteristics Highchromium white cast irons are ferrous alloys containing 1130% Cr and % C along with variable amounts of molybdenum, manganese, copper and nickel [1]. The standard procedure most commonly used for the classification of this kind of cast iron alloy is ASTM A53210 (2014).
Part 1 High chromium cast iron machining and cutting tool selection High chromium cast iron is a kind of high hardness and high strength alloy white cast iron with high corrosion resistance wearresistant, high chrome cast iron in the case without any heat treatment, the generally hardness of HRC45 or more, the tensile strength 650 ~ 850MPa.

of chromium cast iron microstructure and its resistance on erosion wears. Separate part of paper was devoted to discuss the bimetallic castings with chromium cast iron layer as well as typical applications of chromium cast iron castings in minig, proccesing, metallurgical and power industry.
2. High chromium white cast iron. Due to the superior abrasion and corrosion resistance, high chromium white cast irons (HCWCI) are widely applied in industrial products, especially in mining, crushing, drilling and so on. The high abrasion resistance of HCWCI is related to chromium .
A high strength high chromium cast iron contains fine particle precipitated hard carbide. The precipitated hard carbide has an average particle size of 20 µm or less, in a martensite matrix with a hardness of Hv 500 or more, and has area ratio of from 30% to 45%. The precipitated hard carbide has a spheroidal ratio (surface area of sphere circumscribing the precipitated hard carbide versus ...
Wear resistance of high chromium cast iron is the best Wear resistance of high chromium cast iron is the is most widely used, such as small and medium sized ball mill lining plate, and a small, hammer crusher and hammer mill, etc.. View More
High chromium Cast Iron Balls. High chromium ball also known as wearresistant steel ball,are widely used in the ball mill grinding process. ... No Breakage Grinding Steel Balls for mining and Cement / steel mill media. Cast iron and forged Grinding Steel balls, Dia 20140mm grinding media ball.
The mechanical properties of high chromium cast irons are better than those of the high silicon cast irons. The highchromium cast irons respond to heat treatment when the carbon and chromium contents are appropriately adjusted. However, machining of these alloys is very difficult.
Grey cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a grey appearance. It is the most commonly used cast iron and the most widely used cast material based on weight. Most cast irons have a chemical composition of –% carbon, 1–3% silicon, and the remainder iron.
and high abrasion, the more expensive highCr white cast irons can be cost effective (Farge and Barclay, 1975). Our previous research (Blickensderfer, et al., 1983) showed that the impact resistance of highchromium white cast iron is greatly affected by heat treatment. Improvement of grinding media has been a slow process.
is a high chromium white cast iron that is used where high corrosion and abrasion resistance are required. It also has excellent growth and scaling resistance under oxidising conditions. A modified can be used where greater corrosion, oxidation and erosion resistance is required.
