Main causes of subsurface bubble formation in 1.8916 EN 10025-6 high strength steel

The difference between q345 and q235 steel 1.8916 EN 10025-6 high strength steel
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

The company mainly supplies 1.8916 EN 10025-6 high strength steel steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of 1.8916 EN 10025-6 high strength steel steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

Hot rolled 1.8916 EN 10025-6 high strength steel steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the 1.8916 EN 10025-6 high strength steel processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, 1.8916 EN 10025-6 high strength steel, 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.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
