Product details

A105 carbon steel is a kind of carbon structural steel, with good weldability, machinability, corrosion resistance and high temperature stability, widely used in petroleum, electric power and other industries.

The chemical composition of A105 carbon steel rod includes carbon, silicon, manganese, phosphorus and sulfur and other elements, which has a low carbon content, and will not produce obvious pores and cracks in the welding process, which is easy to weld.

In addition, the A105 carbon steel rod also has high hardness and strength, but it is easy to process and process, has good corrosion resistance, can resist the erosion of most chemical substances, and can run stable in high temperature environment for a long time, not easy to be deformed by heat.

In terms of application, A105 carbon steel rod is widely used in pipeline manufacturing in petroleum, electric power and other industries, with excellent pressure resistance and corrosion resistance, and can be used to manufacture various mechanical parts, such as bearings, gears, bolts and so on.

Product production process

Low-carbon Steel 

Low-carbon steel, commonly known as mild steel, is by far the most common type of steel. Because of its low cost and material properties, low-carbon steel is suitable for a wide range of applications. Low-carbon steel contains approximately 0.05-0.25% carbon, making it malleable and ductile. Mild steel has a low tensile strength, but it is inexpensive and straightforward to form; carburizing can increase surface hardness.



High-strength, low-alloy steels (HSLA) are also categorized as low-carbon steels, with other ingredients including copper, nickel, vanadium, and molybdenum. Together, these can account for up to 10% of the steel composition. As the name implies, high-strength, low-alloy steels have higher strengths due to heat treatment. They also retain ductility, allowing them to be readily formed and machined. HSLA is more corrosion-resistant than regular low-carbon steel.



Medium-carbon Steel

Medium-carbon steel has 0.30 – 0.50% carbon and 0.60 – 1.65% manganese. This steel’s mechanical properties can be enhanced by a heat treatment involving austenitizing, followed by quenching and tempering, giving them a martensitic microstructure.



Heat treatment is only possible on extremely thin portions. However, steel can add additional alloying elements such as chromium, molybdenum, and nickel to increase its capacity to be heat treated and thus hardened.



Hardened medium-carbon steels have greater strength than low-carbon steels but at the sacrifice of ductility and toughness. This steel is mostly used in manufacturing machine components like shafts, axles, gears, crankshafts, couplings, and forgings. Still, it may also be used in rails and railway wheels.



High-carbon Steel

High-carbon steel has 0.60– 1.00% carbon and 0.30 – 0.90% manganese. It possesses the greatest hardness and toughness of carbon steel but the least ductility. Because they are nearly always hardened and tempered, high-carbon steels are extremely wear-resistant. High carbon steels might be employed in springs, rope wires, hammers, screwdrivers, and wrenches.



Tool steels and die steels are high-carbon steels containing extra alloying elements such as chromium, vanadium, molybdenum, and tungsten. The incorporation of these elements leads to particularly tough wear-resistant steel, which is a consequence of the production of carbide compounds like tungsten carbide (WC).



Properties And Applications of Common Carbon Steel Grades

Carbon steel comes in various forms, and can be used in many industries and sectors. Low-carbon steels are frequently used in vehicle body components, structural forms (I-beams, channel and angle iron), pipelines, building and bridge components, and food cans. Medium-carbon steels are frequently used for railway tracks, train wheels, crankshafts, and gears and machinery parts needing this combination of qualities because of their high strength, resistance to wear, and toughness. High-carbon steels are utilized in cutting tools, springs, great-strength wire, and dies due to their high wear resistance and hardness.



Low-carbon, medium-carbon, and high-carbon steel correspond to some common grades. The following table compares several carbon steel grades’ examples, qualities, and applications.

AISI/ASTM name	Carbon content (%)	Tensile strength (MPa)	Yield strength (MPa)	Ductility (% elongation in 50 mm)	Applications
1010	0.1	325	180	28	Automobile panels, nails, wire
1020	0.2	380	205	25	Pipes, structural steel, sheet steel
A36	0.29	400	220	23	Structural
A516 Grade 70	0.31	485	260	21	Low-temperature pressure vessels
1030	0.27 – 0.34	460	325	12	Machinery parts, gears, shifts, axles, bolts
1040	0.37 – 0.44	620	415	25	Crankshafts, couplings, cold headed parts.
1080	0.75 – 0.88	924	440	12	Music wire
1095	0.90 – 1.04	665	380	10	Springs, cutting tools
