q235nhd weathering steel is composed of a base plate and a wear-resistant layer, generally using Q235, 16Mn and other steel plates as the base plate, and then surface surfacing wear-resistant alloys, and after the surfacing process of anti-deformation measures as well as zui after the shaping and made.
The performance characteristics of q235nhd weathering steel are mainly as follows:
1, due to the use of automatic welding machine surfacing production and shaping treatment, so the steel plate has a flat and beautiful surface;
2, compared with ordinary steel plate, stainless steel plate, etc., there are zhuo yue wear-resistant characteristics, its hardness value is above HRC56, which can not be reached by general steel plate;
3,Compared with the traditional manual surfacing and on-site surfacing process, it can realise batch production, so it has lower production cost;
4, the combination of the surfacing layer and the substrate is good, with superior fusion strength;
5, can be cut, bending, opening, welding and other methods of processing treatment, so that it has the diversity of applications;
6, due to q235nhd weathering steel surface hardness reaches HRC60 above, the substrate also has a certain medium strength, so that it has a medium impact resistance;
7, its cladding layer organisation for chromium compounds, etc., the hardness value of the steel plate has a superior heat resistance that is not affected by high temperatures below 800 degrees Celsius;
8, because q235nhd weathering steel substrate is generally mild steel or low alloy steel plate, welding performance is better, can be interconnected with other components, so that can be made into a lot of different shapes of reliable components.
Due to the above characteristics of q235nhd weathering steel, and as a wear-resistant material can be cut, bent, open hole, welding and other processing performance, so in the cement industry vertical mill, powder selector, raw material conveying, clinker conveying and other easy to wear parts can be widely used.
