How to distinguish the stainless steel ball slides
As an important part of the steel ball drawer slide, the steel ball plays a decisive role in the quality of the steel ball drawer slide.
There are many types of stainless steel balls, which can be divided into several categories according to the organizational structure at room temperature:
1) Austenitic steel, typically 201, 202, 302, 304, 304HC, 304L, 316, 316L, this kind of stainless steel contains nickel, has strong anti-rust and anti-corrosion properties, this kind of stainless steel is non-magnetic, but at work Magnetic properties can be generated and the magnetic properties can be removed by heat treatment.
2) Martensitic steel or ferrite, this type is generally 4 series stainless steel, 410, 420, 430, 420C, 440, 440C. These stainless steels contain only chromium and do not contain nickel, so the rust and corrosion resistance is not as good as Aussie. Body steel ball. This kind of stainless steel ball can’t be demagnetized, but the martensitic steel has a unique advantage: it can be hardened by heat treatment, which is more suitable for finishing and has strong wear resistance.
