Usage and Applications of Hot Rolled Steel Round Bar with High Quality for Construction:

1. Common Steel Round Bar of 8-25mm, or small round is mostly used for straight bundles supply, and used for steel, bolts and various mechanical parts. While the bigger round bar, or more than 25mm hot rolled bar, is mainly for the manufacture of mechanical parts or for seamless steel billet.

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

3. Besides, we can supply some especial material steel round bar that can be used for main shaft of steamer, hummer shank, with big section and supper force.

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A1: All products offered byOKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What makes stainless steel stainless?

A2: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q3: Can stainless steel rust?

A3: Stainless does not "rust" as you think of regular steel rusting with a red oxide on the surface that flakes off. If you see red rust it is probably due to some iron particles that have contaminated the surface of the stainless steel and it is these iron particles that are rusting. Look at the source of the rusting and see if you can remove it from the surface.

Q:How can a round steel weld on a flat steel plate be flat and qualified?
If it is full weld, for strong, don't groove. There must be no problem with the welding. If you hit the groove, it will deform. When welding, you should do spot welding and diagonal welding. I think you should be able to understand this, but I don't know what you are using for it,
Q:Embedded bolts M24 why use M25 round steel?
Such as using 24 of the round steel, worried about the surface quality of steel when the processing can not be nominal diameter 24 of the standard thread, of course, the election is too large and wasteful, so generally choose 25 of the round bar,
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:How many positive and negative tolerances are allowed for round steel GB?
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. 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. Among 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 are the main differences between wrought round steel, hot rolled round steel and cold drawn round steel? Where are they used separately?
The main differences are in mechanical properties. I don't know very well how to make round steel, I can't compare it. Forged round steel is expected to be used in the processing of some special performance requirements.
Q:Weight algorithm of round steel
1, the appearance is different, round steel appearance of round, no grain without ribs, other steel surface appearance has carved or ribbed, this causes the round bar and concrete bonding force is small, and other steel and concrete bonding force.2 ingredients are different, round steel (grade a steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel. 3 strength, steel and other steel with high strength low strength, namely, diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, and it reinforced the deformation the break before the much smaller.
Q:Round bar, flat steel, not reinforced?
Round steel: 5.5-25 mm small round bars are mostly supplied by straight strips. They are commonly 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 as seamless steel tube billets.
Q:How about tempering No. 45 round bar?
Quenched and tempered steel has two major categories: carbon quenched and tempered steel and alloy quenched and tempered steel. Carbon steel or alloy steel, the control of carbon content is relatively strict. If the carbon content is too high, after quenching and tempering the strength of the workpiece is high, but the toughness is not enough, such as carbon content is too low, toughness and lack of strength. In order to make the quenched and tempered parts get good comprehensive performance, the total carbon content is controlled at 0.30~0.50%.
Q:What is the diameter deviation of 12 mm galvanized round bar?
It is widely used in hardware, building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:The difference between round face and round bar steel on concrete?
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 small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts, and more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
