Stainless SteelBalls are usually produced by the stainless steel forging processsteel ballAt this stage, the commonly used stainless steel ball materials are 201, 302, 304, 316, 316L, 420, 440C.
Stainless steel definition: contains more than 12.5 percent chromium, has a high resistance to chemical substances (acid, alkali, salt) corrosion of steel.
Principle: stainless steel is not rust, but not easy to rust. The principle is to form a layer of dense chromium oxide layer on the surface of the steel by adding chromium element, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel, and achieve the effect of preventing the steel from rusting.
Classification: China National Standard (CNS), Japan Industrial Standard (JIS) and American Iron and Steel Institute (AISI) use three digits to represent different stainless steels, which are widely quoted by industry. Among them, 200 series is chromium-nickel-manganese austenitic stainless steel, 300 series is chromium-nickel austenitic stainless steel, and 400 series chromium stainless steel (commonly known as stainless steel), including martensite and ferrite.
