Q:How many grades of steel are round steel?
Secondly, the round steel only shows the shape of steel, all kinds of steel have round steel, it can not explain the nature and composition of steel.
Q:Can I use steel bar instead of steel bar?
Important stress parts should not be adopted. Reinforced surface made of thread, herringbone bond force is increased to crescent, steel and concrete, reinforced some parts if it is ends with a ribbed design can not bend, it is possible to design directly paste up, it is best to ask the design unit.
Q:What is round steel?
More than 25 mm round steel, mainly used in the manufacture of mechanical parts or between round steel and other steel seamless steel tube blank: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength.2 other components of steel and concrete are not the same, round (a steel) belongs to the ordinary low carbon steel, alloy steel reinforced many other.3 strength is not the same. The low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other small steel however, plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:Will the theoretical weight of thread steel and round steel be the same?
The theoretical weight of threaded steel and round steel is the same. The middle part of the steel bar size ratio is small, the design time actually unit weight are the same, just screw steel crescent and transverse ribs prominent, resulting in heavy steel should be better than the illusion of formula is 0.00617 multiplied by the square of the diameter / m.
Q:How can stainless steel rounds occur? Is it a quality problem?
By the skin bubbles, surface cracks and so on. Crack and steel surface vertical, about 0.8 ~ 1.5mm, no decarburization on both sides, this is caused by the bubble caused by the subcutaneous bubble. The molten steel contains a large amount of gas. When the liquid steel is solidified, the gas is discharged to form bubbles. The outer layer of the slab near the bubble called the subcutaneous bubbles, honeycomb shaped perpendicular to the surface of the billet, billet after rolling, the bubbles inside most welding. But if the subcutaneous bubbles near the slab surface is too close, while heating because of billet surface oxidation or burning of the bubble exposed, the bubble surface is oxidized, thus it is not possible to make the steel welding, surface cracks.
Q:1, three, two, steel, wire rod, round steel what is the difference?
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. 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. Among them, 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:Why do I use the M25 round bar for the embedded bolt M24?
The problem is that the reinforcement of this 36 is not ordinary steel. This steel bar is called general round bar, and its diameter is 36.2MM. Its concentricity is very high, it is a kind of reinforcing steel that is specially designed for bolt
Q:40CrMo what is the round steel material?
High strength, high hardenability, good toughness, little deformation during quenching and high creep strength and lasting strength at high temperature.
Q:The 8 thread can replace the beam stirrups by steel
Fixed beam and beam is set in the stirrups stirrups, stirrup stirrup is higher than that of the non quota subheadings subheadings, because all trouble making and binding stirrups. In addition, need to see which parts of the ring beam.
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.
