Hot rolled Q235NH complete specification mechanical properties

The rolling pipe is made by steel plate with welding process. The rolling pipe is mainly used for conveying water, gas, air, oil and hot water or steam, etc. The rolling pipe has the following characteristics. First, it is easy to process. Welding can be done directly on the basis of steel plates, Q235NH complete specification. Second, the diameter is large, and various large-diameter rolling pipes can be directly customized and processed. Third, the processing speed is fast, saving processing time. Fourth, a small amount of customization can be used for trial proofing to avoid excessive waste.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, Q235NH complete specification, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

Steel plate cutting and machining parts are mainly used in machinery manufacturing, ships building, landscape building, petroleum storage tanks, steel structures and mold processing industries. We can provide finished and semi-finished Q235NH complete specification steel plates products according to the client needs.
