carbon steel round bar supplier
Carbon steel is an alloy containing carbon and iron.The carbon quantity is up to 2.1% by weight. The rise in the carbon percentage elevates steel’s hardness and strength but makes it less ductile. Carbon steel has decent properties like hardness and strength, and it is less economical than other steel.
What is a carbon steel round bar?
Carbon steel bar is a general-purpose steel bar with excellent formability and weldability. There are many areas in which it can be applied, such as auto manufacturing, shipbuilding, the aerospace industry, petrochemical units, auto-power, and wind engines, metalworking machinery, precision tools, etc. We can say carbon steel round bar suppliers cater to the following segments
– Auto manufacturing units
– Aerospace industry
– Auto-power and wind-engine organizations
– Metallurgical machinery
Steel Round Bar undergoes Annealing, Normalized, Quenching, and Tempering. The surface has: Black Finish, Peeled, Rough Turned
Some of the types of CS round bars are
- Carbon Steel Round Bar – C15
comes with a nominal 0.15% carbon content. Generally, C15 is used for cold-headed fasteners and bolts.
- Carbon Steel Round Bar – C20
It is an unalloyed low-carbon mild steel grade. The bar is either a hot rolled or bright drawn finish bar. Mainly used in lightly stressed in the form of bolts, fixings, shafts, spacers, hubs, and bushings.
- Carbon Steel Round Bar – C30
Available as C30 steel, steel plates, and C30 steel sheet. It is a type of high carbon steel plate, steel sheets in EN10250 standard.
- Carbon Steel Round Bar – C40
With medium Carbon ranges from 0.30 to 0.60% & manganese from 0.50 to 1.65%.
- Carbon Steel Round Bar – C45
Also, a medium carbon steel grade with reasonable tensile strength. C45 is widely used for components that need better properties than mild steel at a lower cost.
- Carbon Steel Round Bar – C50
Medium carbon steel is comes with greater strength and hardness .
- Carbon Steel Round Bar – C55
Again, medium carbon steel for greater strength and hardness.
- Carbon Steel Round Bar – C60
With greater carbon quantity (0.60%). Fabrication is muchproblematiccompared low carbon variants. Use to make Shafts, bushings, connecting rods, Mechanical engineering components, and agricultural hand tools.
- Carbon Steel Round Bar – CK15
Plain carbon steel with a nominal 0.15% carbon content.
- Carbon Steel Round Bar – Ck20
It is a Fe-Cr-Ni alloy containing slightly more chromium and noticeably more nickel than the CH-20 grade. Exhibits excellent resistance to dilute sulfuric acid.
- Carbon Steel Round Bar – Ck30
A higher carbon (0.30%) manganese steel within the plain carbon steel alloy family has good ductility.
What is the ASTM A105 round bar?
ASTM A105 steel bar refers to steel specifications for low-carbon forged components. Suppliers stocks several diameters of A105 hot rolled steel round bars to cater to the market demands. A105 steel bars are required by numerous industries including oil & gas.
ASTM A105 round bar is a long, cylinder-shaped metal bar stock.It has many industrial and commercial uses. The most common use is shafted. A105 steel round bar has dimensional precision, high durability, and strength construction in nature. ASTM A105 material undergoes heat treatments like such as annealing, normalizing or normalizing, and tempering. A105 carbon steel round bar is in pressure systems. Content-wise is a low-carbon, manganese, and silicon-containing steel which is similar to AISI 1330, but with lower manganese content. With good machinability carbon steel, A105 round bars are widely used for an ideal finish, long-lasting performance, and corrosion resistance. A105 square bars are broadly used in many industries for manufacturing. It also aids in general repairs of railings and plant equipment. Other common uses include ornamental ironwork, gates and protective barriers on windows
Is A36 and 1018 round bar the same?
They are not the same. Here are the basic differences;
1018 STEEL
1018 can be prepared in cold-drawn or hot-rolled forms.Rarely it is purchased as a cold-drawn product. We’ll assume 1018 is in its cold-drawn state while making this comparison. It was typically available in bar form in numerous sizes and shapes. 1018 steel has many positive characteristics at a good cost. 1018 steel is a mild low-carbon steel with good ductility, hardiness, and strength qualities. 1018 steel is easily welded using most welding processes. This 1018 steel be in square, hexagon, round, and flat bar shapes and can be cut in any specified length.
A36 STEEL
ASTM A36 steel is one of the most extensively manufactured grades of steel bar., It has various applications covering many industries. Similar to 1018, it can be hot-rolled or cold-drawn.typically follows the hot-rolled method. this comparison, we’ll accept A36 is hot rolled. It comes in many unlike bar shapes including squares, rounds, and rectangles.Finds application into channels, angles, I-Beams, and H-Beams. Generallymass-produced as a steel plate product.
Chemically, A36 and 1018 are very similar with the nominal difference
| A36 | 1018 | |
| Iron, Fe | 99% | 98.81-99.26% |
| Carbon, C | 0.26% | 0.18% |
| Manganese, Mn | 0.75% | 0.6-0.9% |
| Phosphorus, P (max) | 0.04% | 0.04% |
| Sulfur, S (max) | 0.05% | 0.05% |
Irrespective of whether the steel is hot rolled or cold drawn has a significant impact on the mechanical properties as shown in the table.
| A36 | 1018 | |
| Tensile Strength | 58,000 psi | 63,000 psi |
| Yield Strength | 36,300 psi | 53,700 psi |
| Elongation (50 mm) | 20% | 15% |
Based on the usage;
1018 steel is used more than A36 for areas that require machining, owing to its response to machining equally well. 1018 is most commonly applied in high-volume screw machine parts with shafts, spindles, pins, and rods. A36 is often a mass steel product for the industrial and construction industries.Uses include making buildings, bridges, railroads, oil rigs, and more. A36 welds easily with any standard welding methods., Comes with lower yield strengths than 1018, so bending is easier
Pricing is a vital factor:
Cold drawing steel is laborious and time taking. The investment of time and labor elevates the price of cold-rolled products. For products with normal quality finishes with high strength and machinability characteristics, A36 makes a preferable choice over 1018 simply because of the reduced price.
Conclusion
The properties of 1018 are superior to A36 in terms of surface finish, and machinability. The greatest is the overall cost involved. While selecting one needs to consider the quality and the purpose of the application.
