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:Which steel wire is the same diameter as round steel more resistant to breaking?
A wire rope is a flexible rope twisted with a plurality of strands or strands of fine steel wire. The wire rope is twisted by multi-layer steel wires and then twisted by a certain number of strands into a spiral rope at the center of the rope core. In material handling machinery, for lifting, traction, tensioning and loading purposes. The wire rope has the advantages of high strength, light weight, stable work, easy breaking and whole breaking, and reliable work.
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?
The weight is 0.395 kilograms / meter by the theory. Can be rolled, is not the foot, the largest is 7.5 diameter, the price depends on the place, and the price is different from place to place
Q:How about the difference between round steel and shaped steel? Where are they mainly used?
Low carbon steel structure steel Q235, Q345 rolled out section is I-shaped, C shape, L shape, flat strip, plate shape... Etc.... Called into "type", as used in steel structure component.
Q:Is round steel bar round steel?
NoRound steel bars refer to hot rolled round steel bars for reinforced concrete. Round bars include high-quality carbon structural steel, round steel, ordinary carbon structural steel round bars, steel bars for prestressed concrete, etc.. Although the shape is round, but the material is different, so steel and round bar is two yards.
Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
Solution heat treatment: the alloy is heated to a single phase at high temperature to maintain constant temperature, so that the excess phase is fully dissolved in the solid solution, and then cooled rapidly to obtain the heat treatment process of supersaturated solid solution.
Q:Difference between cold drawn round steel and round steel
There are different reasons for the residual stress in hot rolled and cold-rolled steel sections, so the distribution of the residual stresses is also quite different. The residual cold-formed steel section stress distribution is curved, and hot rolled steel or steel welding section on the residual stress distribution is thin.
Q:How to determine the welding seam height of steel plate and steel bar?
If the arc surface in the length direction of the steel bar is lapped welded with the steel plate surface, the gap between the steel plate and the round bar is welded by the 2 side welding angle, so that the welded meat is equal to the largest diameter of the round steel arc surface.
Q:What is hot rolling? What is called forging?
And there is no essential difference between the rolling and forging are relying on the plastic deformation of the blank but only the blank rolling machine plates or other similar things can be put in the sheet metal forging blank is processed into a more complex shape
Q:What are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
Cold drawn round steel (don't know, you mean can not cold dial round bar). But I understand by the cold dial round bar Also mainly used in hardware parts processing and production. Such as hinge shaft core or other surface and diameter requirements of production and processing occasions.
