Q:What is the tensile strength of Q235 round steel?
According to the national standard of GB 13013-1991 reinforced hot rolled round steel bars,Q235 reinforcement
Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
Q:Which is stronger, steel pipe or round steel? Which is good at bending?
Of resistance to shearing, of course, of high round steel, generally used with steel tubes (light weight and material saving) for transmitting torque
Q:What is the difference between 40Cr round steel and 40Cr forging parts?
The utility model has the advantages of high strength and good plasticity, and is suitable for making important parts with large force and high requirement.The properties of forgings are superior to those of ordinary ones.
Q:What is the difference between cast iron and round steel?
Is also called round billet cast iron or iron by calcination with heavy machinery forging into steel (called the moral is toughened and hardened into steel or steel), the main component of alloy is composed of iron, carbon and silicon steel just according to the different areas in the use of alloy in carbon and silicon content in different precipitation in steel forging process of carbon and silicon was decreased to different areas of demand.
Q:What's the difference between Q345 round steel and No. 45 round steel material?
Q345: it is a kind of manganese steel (16Mn), yielding strength of 345, good welding performance, commonly used in structural parts welding, low carbon steel, can not be used for quenching or quenching and tempering.No. 45 Steel: high quality carbon structural steel, medium carbon steel. Can be used for quenching or tempering.
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Copper wire and galvanized steel bars can be directly welded together, do not pay attention to;Lightning protection device refers to the lightning receiver, the lead wire, grounding device, surge protector (SPD) and other connected conductor sum.
Q:What is the diameter deviation of 12 mm galvanized round bar?
It is widely used in hardware, building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:Difference between cold drawn round steel and round steel
There are different reasons for the residual stress in hot rolled and cold-rolled steel sections, so the distribution of the residual stresses is also quite different. The residual cold-formed steel section stress distribution is curved, and hot rolled steel or steel welding section on the residual stress distribution is thin.
Q:Are the bolts for the round bar or round steel?
If in some large-scale concrete component under the condition of some units to prevent run mode is used, the bar, the bar is the best quality, and the tensile strength is great, because the price advantage is not, it is generally not recommended to use the bar as a pull screw.
