DETAILED INFORMATION
Alloy-bearing steel SAE 52100 is a high-quality low-alloy steel with high carbon and chromium content. The hardness of SAE 52100 Oil Quenched & Tempered is 28-34 HRC. In SAE 52100 steel, the delivery hardness is less than 250HB after annealing.
Alloy-bearing steel properties of SAE 52100 are chromium and manganese alloy steels. DIN 100Cr6 and GB GCr15 steel are equivalent to SAE 52100 steel. It is possible to replace most applications with each other.
One of the significant beneficiaries of 52100 round steel bars is the airline industry, which can use this alloy to produce bearings and other highly stressed parts. These AISI / SAE 52100 Rods are known for their high wear resistance, heat resistance, hardness, and rolling fatigue strength. The AISI 52100 Alloy Steel Forged Bars are a cost-effective solution for continuous operation at temperatures up to 120°C. AISI 52100 Steel Rod has a Rockwell hardness value of 60 – 67 Rc at room temperature.
Steel AISI / SAE 52100 Hex Bar is preferably remelted using a vacuum arc technique to optimize its performance. AISI 52100 Bright Bars can be hardened through cold and hot working processes and annealing and tempering. Using heat treatment, SAE 52100 Round Bars could be strengthened by annealing and tempering. Due to its combination of tensile strength, hardness, and workability, steel SAE 52100 Bars are helpful for mill rolls and vehicle parts.
Steel Round Bar AISI 52100 is used in bearings in rotating machinery. SAE 52100 is used in anti-friction directions. Micro Metals supplies AISI 52100 round bars, flat bars, hexagonal bars, and steel square blocks. We can provide you with AISI 52100 steel round bars in any length you require. Among its chemical components are Si (0.15-0.35), C (0.98 – 1.10), Cr (1.30-1.60), and Mn (0.25-0.45). At 205 to 538°C (400 to 1000°F), SAE 52100 steel can be hot worked. At 927 to 1205°C (1700 to 2200°F), Aisi 52100 Steel Rod is forged.

Forging properties :
Forging AISI 52100 alloy steel at 927 to 1205°C is not recommended below 925°C. For SAE/AISI 52100 steel, a post-forge equalization treatment at 745oC for 4-6 hours is recommended.
Stress relieving:
Keep it up to 600-700°C, keep it there, and cool the furnace. Mold steel needs to be 187-229HBS hard. Characters remove residual stress and work hardening.
Normalizing :
Heat it to 930-950°C, maintain the temperature, and excellent with air. The hardness should be 302-388HBS.
Annealing:
AISI 52100 alloy steel is annealed at 872°C (1600°F) and then slowly cooled to reduce cold working or machining stresses.

The Benefits of Cold-Rolled Steel:
Steelmaking processes do not involve heating steel to or above its recrystallization temperature. Rolling and forming steel at room temperature requires more pressure. Cold-rolled steel is manipulated well below steel’s recrystallization temperature and offers several advantages.
Strengthening
Cold-rolled steel is significantly stronger than steel that is hot-rolled. Due to strain hardening, the steel becomes stronger as the rollers compress it at room temperature. Cold-rolled steel is typically 20% stronger than hot-rolled steel.
A better finish on the surface
Cold-rolled steel is more robust and has a better surface finish. The surface of cold-rolled steel is smoother and has fewer imperfections than hot-rolled steel. In addition to improving the aesthetics of cold-rolled steel, it makes it a more suitable material for specific applications, such as bridge construction.
Tighter tolerances
Hot rolling allows for tighter tolerances than cold rolling. The term “tolerance in metalworking” refers to the overall thickness of the metal. Cold-rolled steel is typically thinner – without sacrificing strength. Due to this, cold rolling offers tighter tolerances than other steelmaking methods.
Cold-rolled steel has some disadvantages.
The advantages of cold-rolled steel include increased strength, improved surface finish, tighter tolerances, and multiple options. Cold-rolled steel typically costs more to produce than hot-rolled steel. This makes hot rolling more attractive to metalworking companies.
Cold-rolled steel also has a low malleability. Because hot-rolled steel must be heated to or above its recrystallization temperature, it’s easier to deform and manipulate its shape. The cold rolling process, however, involves compressing steel under rollers at room temperature, making it harder to shape.
Application:
SAE1010 is a steel material. Its plastic is robust, easy to form by cold and hot processing, has good cutting performance after normalizing or hardening, excellent weldability, no temper brittleness, and poor hardenability and hardenability.
1. Mainly used in the manufacture of petroleum, chemical, gas separation, and shipping containers, including all kinds of tower vessels, heat exchangers, storage tanks, and tank cars, etc. 2.
