52100 Chromium Steel Balls: Chromium steel balls offer high hardness, resistance to deformation and excellent wear characteristics. AUB's chrome steel balls are made from the highest quality chrome alloy steel and are hardened for maximum strength and longevity. 52100 chrome steel is a material primarily composed of carbon and chromium. This combination makes the metal strong and durable, ideal for a variety of different situations.
Composition and properties
This material is a metal alloy, which means it is the sum of combinations of different metals. The properties of 52100 chrome steel are as follows:
Heat Treatment
When trying to heat treat 52100 chrome steel, heat it to 1500 degrees Fahrenheit. The material is then oil-quenched – this brings it to the required hardness while reducing the risk of cracking. If you want to heat work this material it has to be done between 400-1000 degrees Fahrenheit.
Advantage
Application
Because the material is durable, smooth and can withstand high temperatures, it is ideal for many automotive applications. Use our precision 52100 chrome steel balls in steering wheels, seat tracks, power doors, constant velocity joints and other vital parts of your car. Chromium steel balls and rollers are used by many industries that require excellent precision and durability.
There are many different types of stainless steel balls. Engineers are able to modify this durable and affordable material by combining other materials such as carbon, chromium, nickel, and more. Manufacturers make each grade of stainless steel balls for a specific purpose. By manipulating the composition of elements, you end up with specialized materials, including cutlery, bearings, and more. We specialize in the use of various specialty steels as precision steel balls and rollers in many industries.
Composition and properties
The special composition of our Type 440C Stainless Steel Balls makes them a popular choice. This material is a metal alloy, which means it is composed of various different metals. This results in a stronger, more durable product. The following properties make up 440C stainless steel:
1. Iron – 79.15
2. Chromium – 17
3. Carbon - 1.1
4. Manganese – 1
5. Silicon - 1
6. Molybdenum – 0.75
This stainless steel gives you a product with a density of 7.80 cubic centimeters. On the Rockwell hardness scale, 440C stainless steel has a minimum hardness of 58.
Advantage
This composition results in a material that is hard, strong and resistant to corrosion. Due to the high amount of carbon the material contains, this material is one of the strongest and most durable stainless steel options around.
Application
All of these advantages make this grade one of our most popular ball selections. You'll find our Type 440C stainless steel balls in a variety of cosmetics, agricultural and processing facilities, automotive artifacts, and more. Along with our steel balls, you'll find this material in surgical instruments, quality cutlery, chisels, and more due to its strength and durability.
We supply quality steel balls for many commercial applications across multiple industries. Each of our balls is designed for a different purpose based on the chemical composition of the material. That said, there are many different steels to choose from. If you are unsure which steel is best for your application, our team will be more than happy to assist you with your selection. If you need steel balls with excellent corrosion resistance but don't necessarily need high strength, then our Type 316 stainless steel balls are for you.
316 stainless steel components
All stainless steels are metal alloys. This means they are made of combinations of elements such as chromium, carbon and nickel. Engineers can control the amount of each element to produce a steel suitable for a specific application. Type 316 stainless steel includes:
1. Chromium – 16% – 18%
2. Carbon - .08% max
3. Silicon – up to 1%
4. Molybdenum – 2% - 3%
5. Nickel – 10% - 14%
6. Manganese – up to 2%
7. Phosphorus - .045%
8. Sulfur – 0.03% maximum
This composition gives you a material with excellent resistance to sulfurous acid and other aggressive acids and environments. Type 316 stainless steel has a tensile strength of 90,000 psi and a yield strength of 45,000.
Manufacturing
To produce high quality steel balls, we implement a rigorous manufacturing process resulting in ball bearings that get the job done. This 5-step process includes heading, flashing, heat treating, grinding and polishing.
We offer a wide range of different steel balls, which we tailor for specific industries and tasks. When deciding which material is best for your application, it is important to consider your options and consider the composition of the steel. One of our most popular options is our Type 304 Stainless Steel. The unique design of this steel allows it to serve various industries.
Composition and properties
The engineering behind each grade of stainless steel includes a special combination of different elements that affect the material's properties. Stainless steel is an alloy since it contains several metals. The chemical composition of 304 stainless steel contains the following components:
1. Chromium – 18% - 20%
2. Carbon – .08%
3. Nickel – 8% - 10.5%
4. Manganese – 2%
5. Silicon – up to 1%
6. Phosphorus – 0.045% maximum
7. Sulfur – 0.03% maximum
This specific combination gives you a material with good corrosion resistance, especially to dyes, food and other materials. Type 304 stainless steel has a Rockwell hardness of 70. The tensile strength test for 304 stainless steel is between 80,000 – 180,000 psi. This puts the 304 at the low end of the intensity spectrum.
Advantage
Due to the high chromium content in this steel, it has good corrosion and oxidation resistance. It is also easy to clean and manufacture, making it ideal for a variety of uses in different industries.
