Introduction to WNM600E Steel Plates WNM600E Wear Plates

Introduction to WNM600E steel plate: WNM600E is a wear-resistant plate, W is the acronym of "Wu" Yang Iron and Steel, NM is the acronym of "wear-resistant", 600 is the Brinell hardness value, E is the grade, -40 °C impact. WNM600E implementation standard: WYJ, WNM600E heat treatment delivery status: Q+T (quenched and tempered).
The chemical composition of the wear-resistant layer of the alloy has a carbon content of 4-5%, a chromium content of up to 25-30%, a volume fraction of Cr7C3 carbide in its metallographic arrangement of more than 50%, a microscopic hardness of HRC56-62, and a hardness of chromium carbide HV1400-1800. Since the carbides are distributed in the direction of wear straight, the wear resistance is more than
doubled even when compared with cast alloys of the same composition and hardnessChemical Composition

(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, the data comes from the network, for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions of
GB/T222, and the base plate of the wear-resistant composite steel plate shall be low carbon steel or low alloy. Stainless steel and other resistance materials reflect the superiority of bimetals, the wear-resistant layer resists the wear of the wear medium, and the substrate accepts the load of the medium, so it has good impact resistance. It can accept the impact and abrasion of high drop hoppers in the material handling system.
WNM600E the chemical composition and good heat resistance of the steel plate: the alloy wear-resistant layer is recommended to be used under no more than 600 working conditions, if vanadium, molybdenum and other alloys are included in the alloy wear-resistant layer, the high-temperature wear and tear
recommended application temperature of no more than 800 can be accepted as follows: Ordinary carbon steel substrate is recommended to be used under no more than 380 working conditions; Low-alloy heat-resistant steel plate (15CrMo, 12Cr1MOV, etc.) substrate is recommended to be used under working conditions not higher than 540; Heat-resistant stainless steel substrates are recommended to be used in working conditions not higher than 800.
5. Analysis of chemical composition of WNM600E: WNM600E carbon C: not more than 0.25WNM600E silicon Si: not more than 0.7WNM600E manganese Mn: not more than 1.6WNM600E phosphorus P: not more than 0.025WNM600E sulfur S: not more than 0.01WNM600E chromium Cr: not more than 1.4
6. Analysis of WNM600E mechanical properties: the WNM600E thickness is 8mm-60mm, the tensile strength is not less than 1300MPa, the carbon content in the chemical composition of the wear-resistant layer of the alloy is 4-5%, the chromium content is as high as 25-30%, the volume fraction of Cr7C3 carbide in the metallographic structure reaches more than 50%, the macroscopic hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Since the carbides are distributed vertically in the direction of wear, the wear resistance is more than doubled, even when compared with cast alloys of the same composition and hardness.
7. The substrate of WNM600E composite steel plate with good impact resistance and wear-resistant composite steel is low carbon steel or low alloy. Tough materials such as stainless steel reflect the superiority of bimetal, the wear-resistant layer resists the wear of the wear medium, and the substrate bears the load of the medium, so it has good impact resistance. It can withstand the impact and abrasion of the high drop hopper in the material conveying system, and the WNM600E has good heat resistance, and the alloy wear-resistant layer is used under working conditions of no more than 600 °C, if vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high-temperature wear and tear of no more than 800 °C, and the use temperature is as follows: ordinary carbon steel substrate is not higher than 380 °C. Low-alloy heat-resistant steel plate (15CrMo, 12Cr1MOV, etc.) substrate is not higher than 540°C; Heat-resistant stainless steel substrate is used in working conditions not higher than 800 °C. Uses of WNM600E steel plates: wear-resistant steel plates have high wear resistance and good impact performance, can be cut, bent, welded, etc., and can be connected with other structures by means of welding, plug welding, bolt connection, etc., and have the characteristics of time-saving and convenient in the process of maintenance site, and are widely used
in metallurgy, coal, cement, electric power, glass, mining, building materials, bricks and tiles and other industries, compared with other materials, It has a high cost performance and has been favored by more and more industries and manufacturers.
