Q:What is the difference between 40Cr round steel and 40Cr steel forgings?
Generally speaking the 40Cr steel is a kind of hot rolled steel (rarely cold). The need for heating the material before hot rolling process is or rolled, usually heated to above the recrystallization temperature, then condensation formed after the bar, of course I say is very simple, there are many steps.
Q:The difference between galvanized round bar and galvanized flat steel?
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:Embedded bolts M24 why use M25 round steel?
Because M25 round steel machine processing, the direct use of M24 round steel accuracy is not guaranteed
Q:Why can't the grounding device be replaced by steel bar instead of round steel?
1, it is the surface problem. The bigger the surface, the easier it is to discharge the point.2, the thread steel belongs to high carbon steel, conductivity is inferior to round steel.
Q:Why is round steel more expensive than thread steel?
Round steel has a wide range of applications, many brands and different uses. Such as machining, shipbuilding and other user processing requirements are also different. Such as alloy round steel, Q345B, high carbon steel, 45#, 35#, general round Q235B, mainly material, ingredients, etc..
Q:How do you know the diameter and weight of a round bar?
The weight divided by the length is the bottom area of 2, Wu R - is the bottom area. The diameter is equal to 2R
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.
Q:Why is a steel rope made of many wires rather than a round bar of steel?
The multi ply, in order to increase the cross-sectional area increases the tension will not suddenly broken, fine wire bend more easily, so the bending of wick core can be better, with better lubrication of steel wire rope. If it is a steel bar, it is not easy to bend, it is easy to break suddenly, and the practicability is poor.
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).
Q:Do you need paint for roof lightning proof steel bars?
If the metal surface is coated with a thick layer of insulating paint, it will seriously affect the flashover effect. In the national standard, the metal roof is directly used as a flash receiver. The thickness of the paint used on the roof must be less than the required value. That is what it means.
