Heat Treatment in High Chromium White Cast Iron Ti

The influence of heat treatment on microstructure and mechanical properties of high chromium white cast iron alloyed with titanium was investigated. The austenitizing temperatures of 980°C and 1150°C for 1 hour each followed by tempering at 260°C for 2 hours have been performed and the effect of these treatments on wear resistance/impact toughness combination is reported.

Heat Treatment Technology of High Chromium Iron

As an anti-wear 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 as-cast state, but most of them need heat treatment to meet the hardness requirements.

Analysis of the High Chromium Cast Iron Microstructure

heat treatment parameters, the material properties can be customized for a particular application. The studies let to determinate the optimum heat treatment for this type of cast iron. The best properties were obtained for hardening at 950°C, for other temperature of heat treatments the hardness increased and exceeded 60 HRC units.

Heat Treating of High-Alloy White Irons :: Total

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.

Steels (High Chromium Steels) Stainless Steels

High carbon high chrome steels are heat treatable as a consequence of the higher carbon content, and are known as martensitic stainless steels (e.g. 410, 416). They do, however, exhibit lower corrosion resistance due to chromium depletion of the oxide film. The main advantage of these alloys is the low temperature heat treatment required to

1. During an isothermal hold of the supercooled austenite of types 65Kh6M1.5F3B and 65Kh6M3F3B chrome—molybdenum—vanadium steels in the area of subcritical temperatures (560–680°C) concentration microinhomogeneities or zones occur in it, which causes an increase in hardness and a reduction in specific electrical resistance of the martensite formed in further cooling. The substructure

Effects of Heat-Treatment on the Microstructure and

The variations of microstructure and mechanical properties of a high-chromium cast iron for rolls were studied from as-cast to the final heat treatments. Results show that the as-cast microstructure of the HCCI consists of M 7 C 3 carbide, M 23 C 6 carbide, martensite matrix, and retained austenite. The large dendritic M<sub>7</sub>C<sub>3</sub> carbide surrounds the matrix, and the M<sub>23

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].

To determine an impact of the applied heat treatment operations, testing of mechanical properties and microstructural examinations of the steel with 0.23%, 0.24%, 0.29% and 0.31% C were conducted. This work shows that the mechanical strengths of the alloy steel are improved with increasing the heat treatment temperature.
