If you are familiar with materials, then you know that 1060 carbon steel is big with experts.Whether you are a newbie or an expert with steel options, read on. You will learn all you need to know about the 1060 carbon steel.
What is 1060 Carbon Steel?
1060 carbon steel is a medium-high carbon steel grade. You may classify it as a member of the 10XX steel series. This steel series is a specialized category of carbon steel within the SAE/AISI steel designation system. Usually, you define steel alloys in this series by their carbon content.
1060 carbon steel has about 0.60% total carbon. When you compare it to high carbon steel, however, it has a lower carbon content!
How Is 1060 Carbon Steel Made?
You make 1060 carbon steel using the Basic Oxygen Steelmaking Process (BOS). You begin this process by loading recycled or scrap steel into a BOS vessel. After loading, pour the molten iron directly from the BOS furnace.
The molten liquid you get contains a slew of impurities. It also contains a higher carbon content that exceeds the required amount for 1060 carbon steel.
To reduce the carbon content, lower a water-cooled lance just above the surface of the molten liquid. After you lower the lance, blow high-purity oxygen into the molten iron.
After you blow in oxygen, flux, lime, and other compounds immediately into the mixture. These additions oxidize the excess carbon and impurities.
You can continue the oxidation stage under close and constant monitoring.
The 1060 carbon steel is almost ready after oxidation, but you must ensure that you are on track. To assess the progress you’ve made so far, test a sample to verify its adherence to your specifications. Once you approve it, transfer the steel to a ladle. This ladle will serve as a holding vessel within the ladle furnace.
It’s in the ladle that you put the molten 1060 carbon steel through its final refining process. To complete the procedure, heat the molten carbon steel to a temperature you’ve set. After heating to your chosen temperature, add the alloying elements to get your desired steel composition.
To finalize the process, mold the molten steel into forms like sheets, bars, or tubes. You can use casting machines or steel shaping equipment to mold the 1060 carbon steel.
Characteristics of 1060 Carbon Steel
Some notable properties of the 1060 carbon steel include:
- Hardness
- Relatively easy to customize with heat
- Good machining, as it’s compatible with several CNC machining techniques
- High tensile strength
- The carbon content makes it resistant to corrosion
- Ferromagnetic
- Compared to other steel types, 1060 is only fairly ductile
Pros and Cons of 1060 Carbon Steel
Pros
- Strength and Hardness: You see, 1060 carbon steel is strong and tough. Hence, you can use it for manufacturing parts that can withstand greater loads and stresses.
- Machinability: Despite its hardness, 1060 carbon steel possesses good machinability. Hence, you’d find it a better choice for making consumer-end products.
- Wear Resistance: 1060 carbon steel is also very resistant to abrasion. That’s what makes the metal suitable for situations where you can’t avoid constant friction. Some applications where you need frequent contact friction include cutting tools, gears, clutch discs, etc.
- Affordability: When you compare it to other steel types, 1060 carbon steel is relatively inexpensive. Why? Because producing this carbon steel type is simple. So, if you are sensitive about costs, 1060 carbon steel is your best bet.
Cons
- Ductility: 1060 carbon steel has high-carbon content and low alloying elements. So you may find it more prone to breaking and less ductile than low-carbon steel.
- Corrosion Resistance: You may notice that 1060 carbon steel poorly resists corrosion as it has only a few alloying elements. Air, moisture, alkaline, and acid easily erode the steel. So it rusts and corrodes fairly quickly when you use it.
- Weldability: 1060 carbon steel, because it has a high carbon content, has poor weld performance. Hence, you see that it’s quite susceptible to welding defects like cracks and porosity.
- Maintenance: It’s good that you adopt a regular maintenance schedule for your 1060 carbon steel. Your schedule should include routine oil application and protective storage solutions. Sometimes, frequently carrying out these routines may not be feasible, so you may find it hard to maintain them.
Different Ways of Heat Treating Your 1060 Carbon Steel
One of the primary ways you can alter and improve the quality of 1060 carbon steel is by employing heat treatment options. For this metal especially, treatment options you should consider include:
● Annealing
When you anneal steel, you heat the steel to around 802°C (1472°F) for long enough. After sufficient heating, you let it cool in the furnace.
Annealing helps you relieve the internal stresses in the steel and improve its ductility and machinability.
● Normalizing
When you normalize 1060 carbon steel, you heat it above the critical temperature range of 900°C (1652°F). After heating, you slowly let it cool. Normalizing steel refines its grain structure. After the normalizing process, you end up with steel of uniform microstructure and mechanical properties.
● Quenching
When you quench the 1060 carbon steel, you rapidly cool the heated steel from around 802°C (1472°F). It’s best that you quench in oil or water to enhance its hardness.
● Tempering
To temper steel, you reheat the quenched steel to temperatures below its critical range. You should do this at a temperature high enough to recrystallize and relax its microstructure. This temperature will be between 204°C and 316°C (400°F and 600°F).
Common Forms of 1060 Carbon Steel and the Procedures for Making Them
You will find the 1060 carbon steel available in different forms. These forms possess identical chemical composition. However, the microstructure, properties, and characteristics are different. These forms include:
Casting
You get the cast 1060 carbon steel through casting. When you cast metal, you simply pour the metal into molds of the desired shape. To improve the properties of the metal, you need to process it further. Casting is used to produce more complex shapes.
Forging
You get the forged 1060 carbon steel via forging. For this procedure, you apply pressure at high temperatures to shape the 1060 steel. With forging, you can improve 1060 steel’s tensile strength and toughness.
Rolling
Rolling gives you rolled 1060 carbon steel. When you roll, you reduce the 1060 carbon steel’s thickness and refine its shape.
There are two types of metal rolling you must know about:
- Hot-Rolling: Hot rolling steel means you are heating the steel to a temperature above its recrystallization temperature. When you heat steel to a temperature above its recrystallization temperature, you change the steel into a material called martensite. Martensite has a finer grain structure.
Preferably, you use hot rolling for large-scale production.
Hot rolling improves the ductility and toughness of 1060 steel. However, you could end up with a less hard metal or one with altered dimensional accuracy.
- Cold-Rolling Using the Cold-Rolled Plate: When you prioritize high precision and surface quality, cold rolling is a better option. You can carry out this rolling process at room temperature. After cold rolling, you get processed steel with an elongated grain structure.
The elongated grain structure provides a smoother surface finish and more precise dimensional tolerances for machining.

Comparison With Other Steel Types
As a newbie in material science, you can confuse the 1060 carbon steel with other steels. But, you must keep in mind that all steels are different from one another. They have different uses too.
For example, the 1060 carbon steel has a higher carbon content (.60) than 1045 carbon steel (.45). Hence, when you test its strength, it has more strength. However, you may find it less flexible than 1045 carbon steel.
However, 1060 carbon steel is the brittle one when you compare it to 1095 carbon steel.
When you compare 1060 carbon steel to stainless steel, the alloying constituents are the main difference. Stainless steel contains chromium, phosphorus, molybdenum, and nickel. But you can customize your own 1060 carbon steel content if you want. In addition, stainless steel is more corrosion resistant, and it costs more than 1060 carbon steel.
