Product Description:

Description of steel round bar:

Characteristic:Tungsten-molybdenum high speed steel developed by China,high performance in toughness ,hardness, high temperature hardness.


Festures of steel round bar:

Anneal temperature: 840-860

   Relief annealing temperature: 720-760

   Hardening temperature: 1210-1230

 

Specifications of steel round bar: 

The highest temperature is 427 degrees Celsius.it has good strength,and high quenching property ,the toughness is good and small deformation during quenching.At high temperature, there are high creep strength and endurance strength.It is used in the manufacture of a higher strength and higher quenching and tempering section of the 35CrMo steel, like big locomotive traction gears, supercharger drive gear, rear axle, the connecting rod and the spring load greatly clip.

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: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?
8 there is no regular reinforced steel bars are straight, round, there is straight, as you said 9 M 1, but that's rolling, if their home, can also, engineering is prohibited
Q:The two project is to use rebar or rebar?
It is recommended to use thread steel as far as possible, because the bonding force and holding force of the thread steel is better than that of the round steel, and it is generally known that the tensile pulling force of the round steel is relatively poor.
Q:Embedded bolts M24 why use M25 round steel?
The problem is that the reinforcement of this 36 is not ordinary steel. This steel bar is called general round bar, and its diameter is 36.2MM. Its concentricity is very high, it is a kind of reinforcing steel that is specially designed for bolt
Q:What is the reason that the diameter 130-45 round steel will break after welding?
You say this is a better situation, generally in a few days after welding on the crack, the most afraid of the key parts, to be a major accident. No. 45 steel can not be welded, such as welding, it is necessary to preheat before welding and after welding heat treatment.
Q:What is round steel?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed as millimeters in diameter. For example, "50" means a round steel with a diameter of 50 millimetersRound bar is divided into three kinds of hot rolling, forging and cold drawing. The specification of hot rolled round bar is 5.5-250 millimeters. Among them, 5.5-25 rounds of small round bars are mostly supplied by straight strips. They are commonly used as reinforcing bars, bolts and various mechanical parts;
Q:How to distinguish between cold plating and hot rolled round steel?
Cold galvanizing also called electro galvanized, is the use of the workpiece after electrolysis equipment except oil, after pickling solution into the composition of the zinc salt in the anode and connected electrolytic equipment; cathode zinc plate placed in the workpiece in the electrolysis equipment connected across the power supply is switched on, the current directional moves from the anode to the negative pole, will depositing a layer of zinc on the workpiece.
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:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
Q:Are lightning checks required for galvanized steel, flat steel and round steel?
No, when purchasing hot galvanized round steel and flat steel, please offer the factory certificate and inspection certificate.
