Q:How can a round steel weld on a flat steel plate be flat and qualified?
If it is full weld, for strong, don't groove. There must be no problem with the welding. If you hit the groove, it will deform. When welding, you should do spot welding and diagonal welding. I think you should be able to understand this, but I don't know what you are using for it,
Q:Why is it better to use round steel than flat steel in lightning protection?
Of course, the contact area of flat steel and soil are large, relatively scattered large flow area, the construction is more convenient, in terms of price, we are willing to use flat, as for the problem of anti-corrosion, anti-corrosion paint, zinc can be taken, you know, the thickness of galvanized steel pipe is generally not flat, so true to see the term for the use of galvanized flat steel is not bad.
Q:Are more bars used in high-rise buildings?
The State advocates the use of new steel grades and designs responsive to national policies.Xingang are screw steel, screw thread steel with multiRound bars are often used in stirrups
Q:40CrMo what is the round steel material?
Requirements for the manufacture of 35CrMo steel with higher strength and conditioning section large forgings, such as locomotive traction gears, with supercharger drive gear, the rear axle, the connecting rod and the spring load greatly clip, 2000m can also be used for the following deep oil drill pipe joints and fishing tools etc..
Q:How to make the round welds on flat steel flat and qualified?
It is required that the current is suitable and the bar is stable. If required, the groove can be turned on the round steel to ensure that the welding is beautiful and qualified
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 tensile strength of Q235 round steel?
Nominal diameter 8-20 mm, yield point is greater than or equal to 235MPa, tensile strength greater than or equal to 370MPa, elongation is greater than or equal to 25%.
Q:How about the difference between round steel and shaped steel? Where are they mainly used?
Low carbon steel Q235 steel hot rolled into a round, mainly used in concrete. Medium and high carbon tool steels are wound into large diameter round bars and are used in the machinery industry for cutting into components.
Q:The difference between round face and round bar steel on concrete?
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, and more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:20# difference between round bar and A3 round bar, can they be used separately?
The first floor of the answer is lame, 20 is a low carbon steel, low carbon steel is A3, and the two carbon content are equivalent, both mechanical properties are equivalent, but they are not the same, the 20 steel is high quality carbon steel, carbon structural steel is A3, not to see the difference. 20 steel better quality, chemical composition, impurity content control are better, and A3 to casually, so if you only occasionally used, that is no problem, if often use, it is a better consistency of 20 steel
