Q:Three - grade thread Phi 10 steel can replace a grade Phi 12 round bar? Which elder knows, trouble pointing.
The general situation is not possible, but sometimes as stirrup time, and has little effect on the structure, if 12 reinforced with missing a few, but not on the main force position is possible, sometimes supervision is not allowed.
Q:Can I use steel bar instead of steel bar?
The substitution principle of steel bars is equal section substitution and equal strength substitution. Therefore, we can not use round steel instead of thread steel.
Q:20 round bars are of several grades
At different levels of chemical composition, because of the reinforcing of different chemical composition of the steel, the mechanical indicator will be different. One, two, according to the social needs of Sansteel production power and the development of the material standard, the yield strength, ultimate strength, elongation, low temperature, and weldability are very different, different levels of steel position also have great cooperation. First grade steel yield strength 235MPa, ultimate strength 310MPa, grade two steel yield strength 335MPa, ultimate strength 510MPa, grade three steel yield strength 400MPa, ultimate strength 600MPa.
Q:Which is hard, round steel or screw steel?
If the diameter is the same, of course, the rebar is of great hardness.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.
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Galvanized round bar and galvanized flat steel are of different shapes and different uses.Galvanized 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. Round steel is not the same as other steel bars. Round steel is round in shape and has no ribs and no ribs, which makes the bonding strength between round bar and concrete very small.
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:What is the difference between gcr12 round bar and Cr12 round bar? Can it be used in general?
GCr12 is the bearing steel, belongs to the high carbon chromium bearing steel, the chromium Cr content is about 1.2%, other alloy element's indication method and the alloy structural steel alloy content is same. The utility model is mainly used as a ferrule and a rolling body of a rolling bearing under general service conditions.
Q:Is round steel bar round steel?
Yes.From the shape of points for the light round steel, crescent steel, rebar.From the strength of reinforcement is divided into one level (235), two (335), three (435), four (435)Cold drawn from the production process (first tensioning and long pull method), cold and so on
Q:Why is a steel rope made of many wires rather than a round bar of steel?
It is a strand of steel that bends more easily. In general, but the tensile strength is still a single good, but many shares of a broken, will soon be found, easy to change in time, or a broken, immediately out of the accident.
Q:What is the difference between steel and flat steel, round steel and steel?
On the whole, the square section is square, flat section is rectangular, steel surface after finishing the round steel or steel wire (also called steel, silver bar).
