Usage and Applications of High Quality Round Bar

1) Suitable for making various strong cutting tool abrasion resistance, impact resistance.

2) Used to produce all kinds of high hard and super hard saw blade, drill, tap, broach, gear hob and various kinds of milling cutter.

3) Used for advanced punching die, screw die, and the toughness and complicated shape of the punch, etc.

4) Is used for cold forging die and drawing mode, etc.

5) Recommended watchcase factory, screw factory and other cold stamping products industry use.

Packaging & Delivery of High Quality Round Bar

Packaging Detail: All goods are packed in bundle with steel strips and shipped by break bulk vessel or container (depend on target market and different ports)

Delivery Detail: 45 days

Trade terms: FOB, CFR, CIF

MOQ: 25 tons per specification; we can negotiate the quantity if the specification is normal or we have stock of one specification.

Weight: The price invoicing on theoretical weight basis or actual weight basis depends on customer’s request.

Shipment: The shipment of bulk break or container is depends on customer’s request and the situation of the port of destination.

Documents given: Full set of original clean on board bill of lading; Original signed commercial invoice; Original packing list; Policy of insurance; Certificate of origin and what the target market needs.

Production Flow of High Quality Round Bar

The common processes are preheated forging quenching, dual refinement solution process, cooling quenching and isothermal quenching. We use heat treatment for dual refinement solution process. The main measures process is high temperature solution and refinement cycle. High temperature solution can improve the carbide morphology and particle size. The aim is to make the loop refinement ultrafine austenite grains.

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:What is the tensile strength of round steel bars of diameter 28?
The tensile strength of round steel bars of diameter 28 is 27079.36~33849.2 kg. It is explained as follows: the material of rebar is generally Q235-A carbon structural steel, its yield strength is 235 MPa, tensile strength is 441~550 MPa, and it is 44~55 kg / mm2. The cross-sectional area of 28 mm in diameter is about 615.44 mm2, and its tensile strength is about 27079.36~33849.2 kg.
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: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 is the difference between cast iron and round steel?
Is also called round billet cast iron or iron by calcination with heavy machinery forging into steel (called the moral is toughened and hardened into steel or steel), the main component of alloy is composed of iron, carbon and silicon steel just according to the different areas in the use of alloy in carbon and silicon content in different precipitation in steel forging process of carbon and silicon was decreased to different areas of demand.
Q:Which steel wire is the same diameter as round steel more resistant to breaking?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm of small round bars, mostly straight line bundles of supplies, commonly used as steel, bolts and various mechanical parts; more than 25 millimeters of round steel.
Q:Is there a standard for the grounding of pumping units and the length of the length of the angle steel or round steel?
Yes, the length of the grounding body must not be less than 2.5 meters.
Q:Are lightning checks required for galvanized steel, flat steel and round steel?
When you buy hot galvanized round steel and flat steel, please provide inspection documents. In addition, in the procurement of materials must be explained that hot galvanizing, or else the business to provide you with cold plating will not work; there is a certain price gap between the two.
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Grounding device is an important component of lightning protection device. The earthing device releases the lightning current to the earth, and limits the lightning protection device to the ground voltage not too high. In addition to the independent lightning rod, the grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
Q:Can the same grade steel instead of round bar be ok?
The above analysis, threaded steel than round steel performance is good, in general circumstances can be replaced.
