Q:Could you tell me what is the difference between steel pipe and round steel?
Steel tube or conventional weapons indispensable materials, barrel, barrel to steel pipe manufacturing. The steel pipe can be divided into round tube and special-shaped pipe according to the cross sectional area and shape. Because of the condition of equal circumference, the circle surfaceThe product is the largest and uses round tubes to hold more fluids. In addition, the ring section is subjected to an average force when it is subjected to internal or external radial pressure, so most steel tubes are round tubes.
Q:What is the reason that the diameter 130-45 round steel will break after welding?
Steel No. 45 belongs to medium carbon steel. Because of its high carbon content, it has poor weldability, but its comprehensive property is good. If welding is needed, it needs to be preheated before welding and heat treated after welding to reduce its internal stress. The more commonly used weldability is No. 20 steel. In order to improve the performance of No. 20 steel, heat treatment is usually applied to its surface.
Q:What's the difference between round steel and carbon bound steel?
Shape is different, round steel round appearance, no grain without ribs, carbon steel surface has engraved or ribbed, so that the round bar and concrete bonding force is small, carbon tie steel and concrete bonding force.
Q:How to distinguish between cold plating and hot rolled round steel?
Cold galvanized profiles: cold galvanized is electroplating, is absorbed by the charge, the charge is concentrated in the edge, angle and other cutting-edge, so the inner surface and recess will not be plated phenomenon. The surface of the steel is relatively smooth and bright.Hot dip galvanized bar: hot dip galvanizing is to remove oil, pickling, dipping and drying into the molten zinc bath for a certain period of time. The appearance was galvanized slightly rough, silvery white appearance, easy to produce and process water a few drops of tumor, especially in the one end of the workpiece is more obvious.Galvanized quality certificate must be provided for hot-dip galvanized sections.
Q:4145H round steel is equivalent to the domestic brand?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts; round steel larger than 25 millimeters, mainly used for making machines.
Q:What are the differences between hot rolled stainless steel rounds and cold drawn round ones?
Hot rolled round steel, used in construction and general hardware parts processing is very common. Cold drawn round steel (do not know is not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
Q:12 of the diameter of the round steel can be M12 out of the thread is not
No problem。 M12 coarse thread of the pitch is 1.75, the outer circle to be processed to 11.8mm, the thread of the most beautiful shape. If the outer circle is too large, the tip of the tooth is too small and very easy to deform.
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Grounding device is an important component of lightning protection device. The earthing device releases the lightning current to the earth, and limits the lightning protection device to the ground voltage not too high. In addition to the independent lightning rod, the grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
Q:What is the difference between common wire and high-speed wire?
P line: refers to the use of "ordinary mill (usually open-train double wire rod rolling mill)". The rolling speed of 20-60 meters per second, per root weight (disc) in 0.4-0.6 tons (market show is generally three root six head is a market), in the rolling process can only be cooled by air cooling or air cooling line to ensure product performance.
Q:20# difference between round bar and A3 round bar, can they be used separately?
20# rounds are plain carbon steel, as well as 10#, 20#, 45#, etc.A3 round bar is Q235, grade is ABCDE, etc., commonly used is Q235BIn use performance, 20# hardness is strong, but the elasticity is bad, welding performance is poorA3 hardness is less, but good elasticity, good welding performanceAs for specific can not be replaced, mainly depends on the use of places.
