RR wear-resistant plate
Special structural steel plate with high wear-resistant performance produced by Germany (ThyssenKrupp Steel Company, hereinafter referred to as the company) since the mid-1960s. It is quenched or quenched and tempered. , with a dense martensite or martensite-bainite microstructure. The thickness of steel plates produced can be up to maximum. In addition to the traditional grades, three new grades have been successfully developed: R normalized steel for medium and low wear environments, higher temperature use and super hard grades to meet higher wear requirements. In this way, the available steel plates have a hardness coverage ranging from 3 to B, providing appropriate solutions for almost any use environment. Among all grades, the most commonly used one has a hardness value of B, and its service life can be about twice that of traditional structural steel plates.
For R steel that has been quenched or quenched and tempered, since the maximum hardness of the steel is proportional to its carbon content, in order to obtain the required high hardness, it is essential to maintain a certain carbon content in the steel. . For example, for steel with a nominal hardness of B, it is necessary to maintain approximately . Also note that all R steels also contain the following. Various wear tests have shown that this is very effective in improving the wear resistance of steel, especially against the wear of slightly acidic media. Normalized rolled special wear-resistant structural steel R3 has good surface quality and is especially suitable for applications that require hot forming.
R Wear-resistant steel is a high-tech material that perfectly combines uniform high hardness, excellent toughness, low alloy content and excellent processing performance, making it an ideal material for many applications.
General Information R is a specially made structural steel with high wear resistance. This kind of wear-resistant special structural steel has an average hardness of B, with high hardness and good toughness. Structures built with this kind of steel are stronger, lighter, and can withstand impact loads.
Purpose For wear-exposed structures such as protective padding, housing walls, support and reinforcement plate cutting panels for excavators, mining machines and bulldozers, liners for dump truck bodies, wear plates for mixing elements and conveyor elements , chutes, displays, machine tools, crushers and pulverizers, scrap briquetting presses, blades, paving abrasives and agricultural machinery.
