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:How many tons of pressure can the round steel of 70 inches bear?
This simply refers to the vertical compression. The problem of the bracket is whether the round steel is vertically compressed, whether the stiffness of the structure can be safely supported, whether the supporting foundation can withstand the pressure or not, that is a must be taken into consideration.
Q:Round bars and ribbed stirrups are much better
The flexibility of hot rolled round steel bar is better than that of ribbed steel bar, and its fatigue stress amplitude is wide allowable. It is suitable for the components under dynamic load, as well as lifting rings, rings and lifting workpieces;
Q:45# what are the main rounds for?
45# round steel refers to the cross section of round solid steel. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter
Q:Which steel wire is the same diameter as round steel more resistant to breaking?
The same diameter wire rope and round steel, steel wire rope is more resistant to break.
Q:Weight algorithm of round steel
Round steel weight = density * volume = density * base area * length of round bar.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.
Q:What's the difference between round steel and screw steel? Which is cheaper than steel on the market these days?
Steel is known as hot rolled ribbed bar. The specification of rebar is large, and it belongs to small section steel. It is mainly used for the skeleton of reinforced concrete construction component. Generally required in the use of a certain mechanical strength, bending deformation properties and welding process performance.
Q:Excuse me and steel disc round what is the difference?
Steel wire and round steel are two different materials.
Q:What are the differences between the products made of wrought round steel and hot rolled round steel and tested by mechanical testing after heat treatment?
In comparison, the general longitudinal performance of hot rolled round bar is better than that of transverse or tangential direction, and the difference between the two values is obvious. The banded structure is more obvious in the longitudinal microstructure, and the deformation of non-metallic plastic inclusions is more obvious
Q:How can stainless steel rounds occur? Is it a quality problem?
Cracks caused by inclusions in steel, cracks and steel surface of a certain angle, about 1 ~ 2.5mm, slightly decarburization on both sides, decarburization layer 0.10 ~ 0.15mm. There are inclusions on both sides of the crack and in the tail, and the ferrite band is formed
