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:Requirements for groove welding of grade 22mm round steel and manual arc welding
On the lathe, the car C9 chamfer (the car is sharp and difficult to weld, the car's chamfer is too small, the root is not welded).When welding, pull apart the gap of 2mm above the root clearance, the condition allows the edge to rotate while welding, otherwise it can only be welded in all positions.
Q:Are steel and round steel the same thing?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel.
Q:How to determine the welding seam height of steel plate and steel bar?
If the arc surface in the length direction of the steel bar is lapped welded with the steel plate surface, the gap between the steel plate and the round bar is welded by the 2 side welding angle, so that the welded meat is equal to the largest diameter of the round steel arc surface.
Q:How many positive and negative tolerances are allowed for round steel GB?
Because of the deviation of cold rolled steel plate and hot rolled steel plate is not the same as the.5mm hot rolling strip is usually made of steel plate shear, the thickness deviation according to the different width and different. But the minimum of plus or minus 0.19, the highest of plus or minus 0.29 this standard applies to the diameter of 5.5mm ~ 250mm hot rolled round and length of hot-rolled square steel 5.5mm ~ 200mm.
Q:What is the mechanical properties of No. 40 round bar?
There are 20 kinds of steel classification: carbon steel, alloy steel, carbon structural steel, special purpose and so on. Look at the questions this afternoon and find out about the books. Which type of steel do you ask? This is not clear, I gave up the answer, and then I see your this question.
Q:Difference between cold drawn round steel and round steel
Cold formed steel allows partial buckling of the cross section, thus taking full advantage of the post buckling capacity of the member, while the hot-rolled section does not allow partial buckling of the cross section.
Q:Excuse me and steel disc round what is the difference?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel. 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. Where: 5.5-25 mm small round steel mostly straight bundles of supply, used for steel, bolts and various mechanical parts; greater than 25 mm round steel, seamless steel pipe is mainly used for the manufacture of mechanical parts of the tube, etc..
Q:What is the difference between common wire and high-speed wire?
The universal wire and high speed wire are the wire rods (bars) of the rolling mechanism.High wire: refers to the use of high-speed torsion mill rolling wire rod. The rolling speed of 80-160 M / s, each weight (disc) in 1.8-2.5 tons, tolerance of high precision (up to 0.02mm), in the rolling process by adjusting the process parameters (especially in the cooling line) to ensure the different requirements for the product.
Q:Can the same grade steel instead of round bar be ok?
Tolerable。1. grades of steel are different (chemical composition is different). Round steel (HPB235) is carbon steel, steel is Q235; thread steel is low alloy steel; HRB335 grade steel is 20MnSi (20 manganese silicon); HRB400 grade steel bars are 20MnSiV or 20MnSiNb or 20MnTi etc.;
Q:How to distinguish a round bar from forging? Cold drawing? Hot rolling?
Hot rolled round steel, used in construction and general hardware parts processing is very common. Cold drawn round steel (do not know is 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.
