Cold drawn or cold rolled precision square tube (gb-) is a cold drawn or cold rolled precision square tube with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision square mechanical structure or hydraulic equipment can greatly save machining hours improve material rate and improve product quality.Reinforcing phases such as reinforcing particles, short fibers and whiskers can be added to the solder to form composites.Heidelberg ,Soft blowing treatment of molten steel after calcium treatment can reduce residual inclusions in molten steel and better wrap MNS around al CAS and other cores.After cold drawing and aging treatment, the yield point is improved, the tensile ultimate strength is also increased, and the plasticity continues to decrease. Due to the reduction of internal stress during aging, the modulus can be basically restored. According to this principle, cold drawing or cold drawing of reinforcement or low carbon steel wire rod is often carried out on site or prefabricated component factory, so as to improve yield strength and save steel.Namanga,The surface of galvanized square pipe treated by sand blasting, shot blasting or pickling process is relatively clean, and the oxide scale and rust are removed, which improves the adhesion of the coating. When the installation site unconditionally adopts sand blasting and shot blasting, manual and mechanical derusting can be adopted, but the derusting quality level must be reached.Superior square tubular steel (both P and s ≤ .%)Forging square tube: a kind of pressure processing in which the reciprocating impact force of the forging hammer or the pressure of the press changes the blank into the shape and size we need. It is generally divided into forging and die forging. It is often used to produce large-scale materials and materials with large square tube size.

Square tube for automobile half shaft sleeve (gb-) is a high-quality carbon structural steel and alloy structural steel hot-rolled square tube for automobile half shaft sleeve and drive axle housing.Material classification: square pipe is divided into ordinary carbon steel square pipe and low alloy square pipe.The pressurization size and time are the key to the success or failure of welding. If the square tube synthetic material is not pressurized, a large number of pores will be caused due to the pores of the material itself and the gas generated in the reaction. It is not allowed to leave the reactants in the weld, so it must be densified, usually pressurized during the reaction.Production departmentFunctional index analysis of qb square tube - angular plasticity refers to the power of plastic deformation (permanent deformation) without destruction of qb square tube data under load.Stage ( & mdash; )Steel used & mdash& mdash; Such as bridge steel, ship steel, pressure vessel steel, agricultural machinery steel, etc.

Classification of square tube steel is iron carbon alloy with carbon content of square tube between .% - %. In order to ensure its toughness and plasticity, the carbon content generally does not exceed %. In addition to iron and carbon, the main elements of steel also include silicon, manganese,Heidelberg 38 galvanized pipe, sulfur, phosphorus, etc. There are various classifications of steel and square tubes mainly including the following: square tubes are classified into ordinary steel according to quality (P & le; .%, S & le; .%)production,Heidelberg 22 galvanized square tube,If there is only a single plane weld, the step-by-step back welding shall be adopted from the middle, that is, the arc of the section weld shall be terminated at the section arc.Among them, qb square tube is divided into process & mdash& mdash; Arc welded square pipe, resistance welded square pipe (high frequency and low frequency), gas welded square pipe and furnace welded square pipe are divided by weld & mdash& mdash; Straight seam welded square pipe, spiral welded square pipe.Impact toughness the load acting on the machine part at a great speed by QB is called impact load, and the ability of metal under impact load is called impact toughness.Heidelberg , contraction, meandering, shear and so on, because the strength is also divided into tensile strength, compressive strength,Heidelberg Galvanized grooved steel pipe, shear strength and so on. There is often a definite connection between various strengths. Long term square tube, square rectangular tube, seamless square tube, galvanized square tube and galvanized tube have no turnover to avoid price difference, and the price is % higher than the market price! The price of more than one ton is higher! In normal use, tensile strength is often taken as the fundamental strength gauge needle.Generally speaking, square pipe welding has a process: ignition, pressurization and thermal insulation.
