Q:What's the difference between bearing steel and round steel?
Bearing steel refers to the steel used to make bearings. Round steel is generally referred to as round bar steel. One refers to the material, and the other refers to the profiles. Such as bearings, needle roller raw material is round steel, but also bearing steel.
Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
Q:Is round steel round steel?
The difference between steel and other steel: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other. 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: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, the difference between round steel, screw steel, steel, plate material, steel wire, hope professional answer?
Anything you say can be called steel bar, except steel wire. Round and round is a name, and wire coil, general line.
Q:The difference between 304 stainless steel round bar and bright round bar
Stainless steel rounds are not required on the surface. They may come with black leather. They may be pickling surfaces or cold drawn or polished surfaces;Stainless steel bright round steel refers to polished surface or cold drawn surface round steel.304 is the brand, and the surface quality has nothing to do with.
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
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Copper wire and galvanized steel bars can be directly welded together, do not pay attention to;Lightning protection device refers to the lightning receiver, the lead wire, grounding device, surge protector (SPD) and other connected conductor sum.
Q:Is steel bar round wire? What's the difference? What are the main applications of wire rod?
The difference between steel and other steel: 1 is not the same, round shape light garden, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength of steel and concrete. The other 2 ingredients are not the same, (a steel bar) 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, i.e., 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, larger the deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:Are the bolts for the round bar or round steel?
If in some large-scale concrete component under the condition of some units to prevent run mode is used, the bar, the bar is the best quality, and the tensile strength is great, because the price advantage is not, it is generally not recommended to use the bar as a pull screw.
