CN1150979A - High chromium wear-resistant cast steel

High chromium wear-resistant cast steel is applied to ball grinding machine lining board below 3.0 meters, and be 510 times of ZGMnB its work-ing life; Be applied to large-sized grinder more Cast Iron vs Cast Steel_Steel Castings Wear Resistant May 12, 2017 · Wear resistance . Cast iron typically has better resistance to mechanical wear than steel, especially in friction-wearing situations. The higher graphite content in cast iron creates a graphitic dry lubricant that allows solid surfaces to slide against each other without deteriorating surface quality.

Alloy Steel Liners Introduction Superior performance of Cr-mo alloy steel, it has good strength toughness and wear resistance, high temperature resistance, hydrogen corrosion Wear-resistant and Impact Resistance Martensitic Cr Mo Alloy Steel Coal Mill End Liners. Wear Resistant Liner Introduction Chromium molybdenum alloy steel liner has good hardenability. The coefficient of linear expansion is Effects of heat treatment on wear resistance and fracture The objective of this study is to investigate effects of heat treatment on wear resistance and fracture toughness in duo-cast materials composed of a high-chromium white cast iron and a low-chromium steel as a wear-resistant part and a ductile part, respectively. Different size, volume fraction, and distribution of M7C3 carbides were employed in the wear-resistant part by changing the amount Improving Tribological Properties of Cast Al-Si Alloys applied to cast aluminum alloys, they offer the potential of a cost-effective solution with superior wear-resistant sur-faces. Thermal spray technologies include High Velocity Oxy-Fuel (HVOF), a range of plasma spray systems, cold/warm spraying, detonation gun, and ame spraying (FS) methods (Ref 6). These thermal spray processes allow for applica-

Investigation and application of high strength low alloy

Jul 19, 2013 · By the refinement with rare earth and titanium, the purification with blowing argon and improving the hardenability with boron, the cast steel containing 0·25-0·45%C, 0·5-1·5%Si, 0·5-1·5%Mn, 0·5-1·5%Cr and a small quantity of titanium, boron, rare earth, calcium and aluminium has high tensile strength, impact and fracture toughness and excellent wear resistance. RU2278749C2 - Method for producing bimetallic Translate this pageIt is possible to increase useful life period of tubes for transporting abrasive loose materials in permafrost regions from billets with increased wear resistant layer cast according to invention WEAR RESISTANT HIGH BORON CAST ALLOY - A REVIEWto use the boride as wear resistant skeleton and fabricated the high boron cast alloy for the first time. The matrix and wear-resistant phase here could be controlled by changing carbon and boron concen-trations, this approach makes it possible to design the required microstructure. In addition, high boron cast alloy consumes relatively low amount of ex-

Wear Resistance of Metals - ScienceDirect

Jan 01, 1979 · Nonferrous metals, with the exception of stellites and tungsten carbides, are rarely used for abrasive applications. A great deal of information is available on the abrasive wear resistance of steels and cast irons. This enables a fairly rational approach to the selection of abrasionresistant metals to be carried out. Wear Resistant and Ni Hard Cast Iron CastingsWear Resistant and Ni Hard Cast Iron Castings Cast iron, in the grade normally used for items such as bearing housings, gearboxes or machine beds, has a hardness of about 150 to 200 Brinell. With the addition of alloying elements, usually chrome, nickel or copper, the hardness can be increased to Zhili New Materials - High Chromium cast Iron Bimetal The alloy structure cast steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloy elements on the basis of ordinary carbon steel. high wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other related special properties.
