The standard steel ball used for oil resistance mill test is a standardized testing tool used for oil resistance performance testing. This steel ball is usually made of high-quality steel, and its diameter and quality must comply with international standards. The material of these standard balls is usually high carbon chromium steel or alloy steel, which has high hardness, high strength, and excellent wear and corrosion resistance. It can well simulate the friction and wear situation in actual mechanical equipment.
The diameter of standard steel balls commonly includes specifications such as 3mm, 6mm, 8mm, 10mm, and 12.5mm, and the accuracy levels commonly include G10, G16, G40, and G100. In the oil resistance mill test, G40 grade standard steel balls with a diameter of 6mm are generally selected. In some cases, larger steel balls with diameters such as 8mm and 10mm are also selected for the test to simulate the friction and wear between different machine parts.
The surface treatment of standard steel balls for oil resistance mill testing is usually also very important. Usually, it should use precision friction and heating treatment techniques to improve its surface hardness and wear resistance. This can ensure that the quality and hardness of the standard steel ball are stable during the testing process, thereby ensuring the accuracy and repeatability of the test results.
In summary, the standard steel ball used for oil resistance mill testing is a widely used standardized tool in oil resistance wear performance testing. Its main features include compliance with international standard specifications, diameter and quality meeting test requirements, and precision surface treatment.
