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:How to distinguish between cold plating and hot rolled round steel?
The difference between galvanized products: hot galvanized surface is not cold galvanized, delicate and bright, but the thickness of zinc coating, hot galvanizing is cold galvanized dozens of times. Corrosion resistance is also tens of times zinc plating.
Q:What is hot rolling? What is called forging?
By now most of the forging. The blank is placed in the fingerprint forging mold forging is that there is a free forging is the ancient drama often appear with a hammer blacksmith blacksmith
Q:Can the same grade steel instead of round bar be ok?

Q:Difference between forging and round steel
A forging is a process in which a metal is heated and shaped by plastic deformation or a desired compressive force is applied. This force is typically achieved by using a hammer or pressure. The casting process constructed a fine grain structure and improved the physical properties of the metal. In the practical use of parts, a correct design allows the particles to flow in the direction of the main pressure.
Q:Do you need paint for roof lightning proof steel bars?

One thing, one thing, the same thing is round. However, in the general industry, about 30 of the habit is called bar,
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.
