Introduction
Stainless steel balls are usually produced through a forging process. At this stage, commonly used stainless steel balls are made of 201, 302, 304, 316, 316L, 420 and 440C.
Definition: Steel with a chromium content of more than 12% and resistance to chemical substances.
Principle: Stainless steel does not rust, but it is not easy to rust.
The principle is that by adding chromium elements, a dense chromium oxide layer is formed on the surface of the steel, which can effectively prevent the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel. thereby achieve the effect of preventing steel from rusting.
Classification: China National Standards (CNS), Japanese Industrial Standards (JIS) and American Iron and Steel Institute (AISI) use three digits to indicate different stainless steels, and are widely cited by the industry. Among them, the 200 series are chromium nickel manganese series austenitic stainless steels, the 300 series are chromium nickel austenitic stainless steels, and the 400 series chromium stainless steels (commonly known as stainless steels) include martensite and ferrite.
We mainly export stainless steel balls (201, 304, 316, 420, 420C, 440C, 430). It also produces chrome steel balls (AISI52100, 100CR6, GCR15), carbon steel balls (1015, 1010, 1045, 1085) and other materials of various materials.
Our steel balls are used in many industrial fields, such as precision bearings, automotive parts (brakes, steering gears, spools), bicycles, agitators, electrical appliances, sliders, quick connectors, machine tools, locking mechanisms, conveyor belts, roller skates, pens , Pumps, casters, measuring instruments, valves, etc.
Stainless steel ball 316
Application areas:
316 stainless steel ball is a relatively demanding product, usually used in special industries such as medical equipment, chemical industry, aviation, aerospace, perfume bottles, sprayers, valves, nail polish, human accessories, mobile phone panels.
Features:
Austenitic steel is currently the most high-end steel ball industry, HRC ≤ 26, suitable for industries with high anti-corrosion requirements, all properties are better than 304 stainless steel balls.
Comparison:
316L stainless steel ball is softer and tougher than white, so it is usually used for human body jewelry.
