Usage and Applications of American Standard Round Bar

1. American standard is the most common form of steel as its price is relatively low while it provides material properties that are acceptable for many applications. American standard round bar is often used where large amounts of steel need to be formed, for example as structural steel.

2. And we can use this kind of product on the performance of the mechanical parts if the demand is not very high.

3. Steel round bar is used in construction and a large number of architectural and engineering structures.

4. Some special round bar can be used for automotive engine and transmission components, bearing, rails machine tools and wire rope.

 

Packaging & Delivery of American Standard 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 American Standard 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.

 

 

Quality Assurance of American Standard Round Bar

1. We will strictly inspect our production that we sold according to the customer’s request.

2. Quality should be in conformity with the specification of the manufacturer. Quantity and packing conditions should be in conformity with the term in the contract.

3. Should the packing found damaged, the buyer has the right to claim to the seller.

Q:What is the tensile strength of Q235 round steel?
Nominal diameter 8-20 mm, yield point is greater than or equal to 235MPa, tensile strength greater than or equal to 370MPa, elongation is greater than or equal to 25%.
Q:What is the tensile strength of round steel bars of diameter 28?
The maximum tensile strength of material resistance uniform plastic deformation, tensile specimens before under maximum tensile stress, the deformation is uniform, but beyond the metal after the necking phenomenon began to appear, which produce concentrated deformation; for no (or very small) brittle materials with uniform plastic deformation, it reflects the fault the resistance of the material. The symbol is Rm (GB/T 228-1987, the old GB standard, the tensile strength symbol is b), the unit is MPa.
Q:What are the scientific names of round bar and screw steel?
Steel: steel is commonly known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand.
Q:Are steel and round steel the same thing?
Yuan steel and round steel are the same thing, they are round steel.
Q:45# what are the main rounds for?
45# round bars are divided into three kinds: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:What is galvanized round bar?
A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
Q:What is the difference between the heat treatment of cold drawn round steel and the heat treatment of wrought round steel?
Annealing: the annealing of hypoeutectoid steel workpiece heated to AC3 above 20 - 40 degrees heat after a period of time, furnace cooling (or buried in the sand or lime cooling) to 500 degrees Celsius in air cooling heat treatment process.
Q:What is round steel?
More than 25 mm round steel, mainly used in the manufacture of mechanical parts or between round steel and other steel seamless steel tube blank: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength.2 other components of steel and concrete are not the same, round (a steel) belongs to the ordinary low carbon steel, alloy steel reinforced many other.3 strength is not the same. The low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other small steel however, plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Q:How many meters is the minimum loading surface of galvanized steel wire for grounding grid?
Refers to the galvanized flat steel width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of galvanized steel. Galvanized flat steel can be finished steel, also can be galvanized pipe blank and galvanized belt. With high strength, light structure: strong grid welding structure, so that it has high load, light structure, easy lifting and other features, beautiful appearance, durable.Galvanized flat steel can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:What is the difference between gcr12 round bar and Cr12 round bar? Can it be used in general?
The two are different in chemical composition.Cr12 is a widely used cold work die steel. It has high strength, good hardenability and good wear resistance, but its impact toughness is poor. The content of Cr was 11.50 ~ 13. The utility model is mainly used for cold punching dies and punches, cold cutting shears, drill sleeves, gauges, wire drawing dies, coining dies, drawing dies, drawing dies and thread rolling dies, which have the advantages of small impact load, high abrasion resistance, and high abrasion resistance.
