2When processing the square tube, Q, etc.

STulsaHow to specify the yield point of square tube: if the stress decreases, the upper and lower yield points shall be distinguished. The unit of yield point is nmm (MPA). & upper yield point

CmIn the trend of the times, we will change with the changes of the times,Q345B square tube so that the square tube can be used more widely. In our daily life,32 galvanized square pipeWhat are the key values in the Internet age we will the use of the square tube, so that we can use the square tube more in future production. Next, lets introduce the difference between carbon steel and square tube.

Requirements for samples samples can be taken from metal pipes with qualified appearance. Generally, sawing is adopted.


Functional index analysis of square tube - angular plasticity refers to the power of plastic deformation (permanent deformation) without destruction of square tube data under load.

lIt should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.

XAt present, square tubes also have many good properties, strong corrosion resistance and heat resistance, and are widely used in many scientific and technological fields. Therefore, even so,Q345B square tube wise people still do not stop studying the surface adhesion resistance of square tubes. Square tubes in the future will have better performance and make more important contributions to development.

TWhere can I find it?Mechanical property is an important index to ensure the end use performance (mechanical property) of square pipe, which depends on the chemical composition and heat treatment of steel. In the steel pipe standard, according to different service requirements, the tensile properties (tensile strength, yield strength or yield point, elongation), hardness and toughness indexes, as well as the high and low temperature properties required by users are specified.

hFThe surface compressive stress characteristics of the square tube will be obtained after isothermal quenching.

How to reduce the amount of oxide scale is the key to the heating operation of seamless square tube. Especially when its hot. Starting from the service life of tools and the surface quality of pipes, the requirements are more stringent. For example, hot furnaces are divided into heating furnace and reheating furnace according to their functions; The former is used to heat the blank from normal temperature to processing temperature; The latter is used to reheat the blank to the necessary processing temperature during processing.


Square tube has good machinability,Q345B square tube good cold deformation plasticity and weldability; In addition, the toughness of steel does not decrease much during heat treatment,32 galvanized square pipeWhat are the key values in the Internet age but it has quite high strength and wear resistance, especially when water quenching; However, this steel has great resistance to white spots, temper brittleness and overheating during heat treatment.

planiApplication of square tube products: for mechanical equipment, solar energy equipment steel structure, automobile parts, guardrail and ship internal structure.

AFake and shoddy square tubes are easy to scratch, because the equipment of fake and shoddy material manufacturers is simple and easy to produce burrs and scratch the surface of square tubes. Deep scratches reduce the strength of square tubes.

Square tube is made of steel ingot or solid tube blank through perforation,Galvanized pipe_ Galvanized square pipe_ Seamless steel pipe_ Square tube - Wuxi Jiahang and then made by hot rolling, cold rolling or cold drawing. Square pipe plays an important role in steel pipe industry.

rWhen the square tube is covered, the surface of the square tube shall be ventilated to avoid the collection of water vapor on the surface due to difficult volatilization.

xIHowever, there is a large rate of end in the application of steel pipe, which is mainly due to the trouble of internal and external treatment. The first question is very crucial, and its external quality is very important

Square pipes are mainly used in engineering buildings, glass curtain walls, door and window decoration, steel structures, guardrails, machinery, automobiles, household appliances, shipbuilding, containers electric power, agricultural construction, agricultural greenhouses bicycle frames, motorcycle frames, shelves, fitness equipment, leisure and tourism, steel furniture, various specifications of oil casing, oil pipes and pipeline pipes, water, gas, sewage, air Heating and other fluid transportation, fire fighting and support
