Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Bor,Stretch punching by steel plate equipment; The main purpose is to be used in the structure of scaffold.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Subotica,I-beam, whether ordinary or light,BorHow much is a meter of DN100 welded pipe, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V,BorQ345B welded pipe manufacturer, and the macro hardness is - HRC Judged as failing.

Some applications of I-beam: The cold-rolled stainless steel pipe has the advantages of large yield coefficient, bending and so on. In order to reach the health grade standard of stainless steel pipeline, the pipeline after cold rolling must undergo bright annealing, demagnetization, pickling, calibration and other procedures.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties,BorQ345B seamless pipe factory, chemical properties, weldability and structural size of I-beam.Inspection environment,Classification introductionStages needing attention in the production and manufacture of alloy tubes The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.

Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Promotion The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Product description of galvanized pipeDue to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.Bor, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, gas nitriding is widely used in the production of alloy steel pipe.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlement
