Description
Metal balls are rolling spherical elements used in check valves and ball valves, bearings and other mechanical equipment that provide rotational or linear motion. They are usually made of alloy steel, carbon steel or stainless steel.
The steel balls are made of the highest quality chrome alloy steel and are hardened to achieve maximum strength and service life.
Chrome steel is one of a class of non-stainless steels, such as AISI 52100, En31, SUJ2, 100Cr6, 100C6, DIN 5401, and can be used for bearings, tools, drill bits and utensils.
In addition, the company has advanced production equipment and complete testing equipment, including low-speed cold heads, high-speed cold heads, flashing machines, ball mills, grinders and heat treatment devices. Through comprehensive testing technology, reliable product quality can be further ensured. Through Rockwell instrument, electronic compression tester, optical microscope, metallographic microscope, appearance profiler, laser surface roughness tester, automatic appearance tester and steel ball vibration tester for testing.
Apllication
Ideal applications for chrome balls include rolling media, ball bearings, drawer slides, writing instruments, vibration polishing, linear motion components, and check valves.
