KmTBCr28 has the main elements of Chrome 28%, low Carbon with hardness of 430 in Brinell.
KmTBCr28 is a corrosion resistant white iron suitable for low pH corrosion duties, where erosive wear is also a problem.
KmTBCr28: its hardness is 430 in Brinell and suitable for corrosive applications where pH is below 4.
The bimetal wear-resistant pipe is composed of an outer wall and an inner lining. The outer wall is a seamless steel pipe with a thickness of 6-20mm, and the inner lining is a high-chromium-nickel alloy with a thickness of 12-30mm. Casting, this product makes full use of the high pressure bearing capacity, good welding performance and high hardness of high chromium-nickel alloy (HRC30-50) of seamless steel pipe. It is an ideal wear-resistant conveying pipeline.
The outer steel body of the bimetal wear-resistant pipe is made according to the design requirements. The outer arc of the inner wall of the steel needs to be welded and attached to the wear-resistant layer, so that the wear-resistant layer can be firmly attached to the inner wall of the pipe.

KMTBCr28 bimetal wear-resistant elbow has increasingly become a more reliable anti-wear solution for material conveying systems in industries such as electric power, steel, chemical industry, and smelting because of its good wear resistance and reliable welding performance.
Wear resistance: hardness HRC>35, with good wear resistance and thermal stability.
Impact resistance The joint surface of the two metals is completely metallurgical, and the thermal expansion coefficients of the two are equivalent, and there will be no expansion and contraction cracking.
Heat resistance and corrosion resistance: in wet state, under the action of corrosive medium and particle scouring, it is more suitable to use the hardness alloy used in the as-cast state;
The product has good compactness, uniform thickness and stable quality.
KMTBCr28 bimetallic composite wear-resistant pipe came into being and has been widely used since the late 1990s. KMTBCr28 bimetallic composite elbow can not only ensure the requirements of pipeline toughness, weldability and strength (compression resistance), but also ensure sufficient wear resistance. It is an ideal solution for wear-resistant pipelines for material transportation.
