there is still a big gap in the production technology of C-section steel between China and foreign countries.I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Paige , According to the pipe wall thickness, pipes made of relatively thin materials such as steel strip can be welded with high frequency, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃Mehendi Ganjie,However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.In order to make the welded pipe have the required mechanical,Paige How much is galvanized pipe DN65 per meter, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.

I-beam is widely usedWelded thin-walled pipe: mainly used for making furniture, toys, lamps, etc. In recent years, thin-walled tubes made of stainless steel strip are widely used, such as high furniture, decoration, fence and so on.The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc.,Paige 45crmo alloy pipe, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.Discount,The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment, and its application range is expected to be further expanded. Small longitudinal crackStages needing attention in the production and manufacture of alloy tubes

→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Quality documents,At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications,Paige 80 welded pipe more than one meter, control of welding process parameters and operation methods dimensions and relevant standards.The fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection, post welding appearance quality inspection, and post welding nondestructive testing if necessary. Control the welding level and the amount of welding materials at each crossing.H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.Paige ,Last week the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.With the development of steel structure buildings, only I-beam is not enough, that is, which is easy to lose stability for load-bearing columns.
