 Usage and Applications of Carbon Steel Round Bar

Carbon steel round bar is the most common form of steel because its price is relatively low while it provides material properties that are acceptable for many applications, more so than iron. It is often used when large quantities of steel are needed, for example as structural steel. The density of this product is approximately 7.85g/cm³ and the young's modulus, like all steels.

Production Flow of Carbon Steel Round Bar

1. 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.

2. EAF+LF+VD+ Forged+ Heat Treatment

FAQ:

Q1: How do we guarantee the quality of our products?

A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

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.

Q:The 8 thread can replace the beam stirrups by steel
Fixed beam and beam is set in the stirrups stirrups, stirrup stirrup is higher than that of the non quota subheadings subheadings, because all trouble making and binding stirrups. In addition, need to see which parts of the ring beam.
Q:Why is it better to use round steel than flat steel in lightning protection?
From the cross section, thermal stability as long as meet the discharge current can be, but from the lightning protection downlead selection, selection of round steel in order to prevent the tip discharge, so we generally do not choose flat edges as grounding, buried in the earth round and not flat how much difference, but in the case of the same section
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:Why is round steel more expensive than thread steel?
Round steel has a wide range of applications, many brands and different uses. Such as machining, shipbuilding and other user processing requirements are also different. Such as alloy round steel, Q345B, high carbon steel, 45#, 35#, general round Q235B, mainly material, ingredients, etc..
Q:What's the difference between round steel and other steel bars?
Different appearance, round steel appearance garden, no grain without rib, other steel surface has carved or ribbed. This causes the round bar and concrete bonding force is small, and other steel and concrete bonding force
Q:4145H round steel is equivalent to the domestic brand?
4145H rounds are used in oil drilling tools and are often replaced by 42CrMo in the industry.
Q:How to make the round welds on flat steel flat and qualified?
It is required that the current is suitable and the bar is stable. If required, the groove can be turned on the round steel to ensure that the welding is beautiful and qualified
Q:Q235 and mechanical properties of hot rolled steel cold drawn steel have what difference, Q235 hot rolled steel with 12 combined shearing machine has a number of very hard, the damage of the blades, why
The difference between hot rolled steel and cold rolled steelHot rolled steel contains slightly higher carbon content than cold rolled steel. The density is the same in cases where the composition is not constant. But if the composition is different, such as stainless steel, whether cold-rolled or hot rolled steel, the density is about 7.9g/cm3. Specific depends on the ingredients, hot-rolled steel plate is only better ductility, steel is also under pressure.Hot-rolled steel is divided into structural steel, low carbon steel, welding bottle steel, and then according to various kinds of steel to find the steel that you need, check the density and composition of the specific steel.Hot rolled steel is low in hardness, easy to process and good in ductility.
Q:What is the diameter deviation of 12 mm galvanized round bar?
The allowable deviation of dia 12 is + 0.3mm. The name of this specification is: GB1499.1-2008, reinforced concrete, steel, first parts: hot rolled round steel bar, on the third page of the book.
Q:What is galvanized round bar?
A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
