Two different heat treatment cycles were used; the first one was applied by austenitizing at 980°C for one hour and tempering at 260°C for 2 hrs. The second 

The pin-on-disk wear test and solid particle erosion test were used to investigate the wear resistance property of both high chromium white cast iron and multi- 

ABSTRACT: High-chromium white cast iron contains chromium carbides that provide excellent wear resistance, but also cause poor fracture properties. Heat treatments are applied in an attempt to decrease the angularity of the eutectic carbides and to improve the toughness of the matrix by intentionally creating a high fraction of retained austenite,

The invention discloses a heat-treatment method of high-chromium wear-resistant white cast iron Cr28. According to the invention, high-chromium wear-resistant white cast iron Cr28 is heated to 1000-1050 DEG C; the white cast iron Cr28 is heated and the temperature is maintained for 1.5-3h; the white cast iron Cr28 is air-cooled to room temperature; the white cast iron Cr28 is heated to 710-730

Process/ Alloy has been developed for the production of high chrome high carbon cast iron with improved wear resistance. Heat Treatment has been optimized to get better wear resistance. Oil temperature and viscosity of the oil have been optimized to have a faster quenching rate and also to achieve distortion-free grinding media.

cooperate to specify the composition, heat treatment, and foundry practice The high-alloy white cast irons fall into three major groups:.

The annealing of high-chromium white cast iron alloys is conducted when it is necessary to machine the pieces before destabilization.

The invention discloses a heat-treatment method of high-chromium wear-resistant white cast iron Cr28. According to the invention, high-chromium wear-resistant white cast iron Cr28 is

the nickel-chromium martensitic white irons, containing up to about 7% ni and 11% cr, usually put into service after only a low-temperature heat treatment at 230 to 290c to temper the martensite and to increase toughness. if retained austenite is present and the iron therefore has less than optimum hardness, a subzero treatment down to liquid

High chromium white cast irons must be heat treated to develop the full hardness and maximum wear resistance. The destabilization (hardening) heat treatment is 

Although high chromium white iron (Cr15Mo3) has an excellent wear-resisting property,the rising price of ferro-molybdenum limits its application. Wang Jingjing[56]has developedCr15Mn5Si3white iron using the way of Mn replacing Mo. The structure and performance ofCr15Mn5Si3has been close to that of Cr15Mo3white iron, while more retained

Destabilisation (critical heat treatment) of austenite at 970°C for 2·5 h followed by annealing (subcritical heat treatment) at 600°C for 13 h results in massive precipitation of M23C6 carbide

The invention discloses a heat-treatment method of high-chromium wear-resistant white cast iron Cr28. According to the invention, high-chromium 

Heat Treatment Tips and Notes for ASTM A532 Austenitization Austenitization must be done to castings made from chrome white iron to ensure a martensitic matrix and provide the highest toughness and abrasion resistance possible. The chemical composition of the casting will determine the correct austenitizing temperature and time.

In this context, the properties of this alloy, containing 22% chromium and 3% carbon, were investigated after applying different heat treatments and their 

The most commonly used high-chromium white cast iron (HCWCI) is the hypoeutectic white cast iron that contains 2-3.5 wt.% C and 10-30% Cr. This type of material 

In the as-cast condition, the microstructure of high chromium molybdenum white iron consists essentially of dendrites of austenite in a matrix of eutectic mixture of austenite and (Fe, Cr)7C3carbides [ , ]. For many applications, castings are heat treated prior to service to increase the wear resistance as well as impact toughness.

Alloy steels types, properties and uses. Cast Iron: Grey, white, ductile and malleable cast iron. in the range of 0.3% to 0.7% Are popularly known as machinery steels Are easily hardened by heat treatment. High carbon steels Have carbon contents between 0.7 and 1.4 wt%, are the hardest, strongest, and yet least ductile of the carbon steels

The heat treatment process of high chromium cast iron grinding ball includes wind quenching, oil quenching, and special quenching solution treatment. After repeated test and mining, the oil quenching can fully meet all its technical specifications The consumption of iron ore is twice that of iron ore.
