Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
The general drawing bar is 6 meters, some ribbed bars 9 meters and 12 meters two tons of steel; a number of roots can not say, can be 1 or 100 roots, the length of thickness do not know how to tell you how many tons of reinforced root ah.
Q:Are steel and round steel the same thing?
Yuan steel and round steel are the same thing, they are round steel.
Q:What is the difference between 40Cr round steel and 40Cr steel forgings?
But 40Cr forgings are objects that are subjected to pressure by plastic deformation to shape a desired shape or suitable compressive force. (usually done by using hammers or pressure).
Q:Round bars and ribbed stirrups are much better
Hot rolled ribbed steel bar with high strength, suitable for large component high-rise buildings under gravity loads, but also because of its surface shape can provide grip and end without hook, the corresponding anchorage length is short, the material.
Q:45# what are the main rounds for?
45# round bars are divided into three kinds: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of 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:Weight algorithm of round steel
1, the appearance is different, round steel appearance of round, no grain without ribs, other steel surface appearance has carved or ribbed, this causes the round bar and concrete bonding force is small, and other steel and concrete bonding force.2 ingredients are different, round steel (grade a steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel. 3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller.
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:Is there any technique for welding round steel?
Weldment pair:Welding round steel, joining two end, processing 30 degrees slope, center left 3--4mm welding root, two pieces of welding set time, the center stay 4--5mm gap, spot welding positioning.
Q:Why do I use the M25 round bar for the embedded bolt M24?
Because M25 round steel machine processing, the direct use of M24 round steel accuracy is not guaranteed
