Hardened stainless steel ball is generally made of stainless steel ball made by forging process. The main reason why stainless steel does not easily rust is the addition of a certain amount of chromium, which can form a dense layer of chromium oxide on the surface of steel, which can effectively block the re-contact between steel and air, making the oxygen in the air unable to Into the steel, it can achieve the effect of preventing the rust of the hardened stainless steel ball.
From the analysis of material properties, in fact, the main material for hardened stainless steel balls is hardened stainless steel. This steel is a martensitic precipitation hardening stainless steel. Its strength is achieved by martensitic transformation and aging hardening. . Because this steel is low-carbon, high-chromium, and contains copper, its corrosion resistance is better than those of martinite steels such as Cr13 type, 9Cr18, 1Cr17Ni2, and so on.
Because of this, this hardened stainless steel ball not only has good stainless performance, but also has certain acid, alkali, and salt corrosion resistance. Applicable to all kinds of precision machinery, bearings, electrical equipment, transportation tools, household appliances and so on. It is mostly used to make parts that are resistant to atmospheric, water vapor, water and oxidizing acids. Product specifications are mainly Φ2.0-Φ25.4.
It is because of this performance that this hardened stainless steel ball is mainly used in industries that require high precision and anti-rust performance, such as motorcycle accessories, pulleys, stainless steel bearings, plastic bearings, handicrafts, valves, and oil. . This martensitic stainless steel, like the modulated steel, can be quenched, tempered and annealed.
In hardened stainless steel balls, the main alloying elements are iron, chromium and carbon. This hardened stainless steel ball can be adjusted by its heat treatment (quenching, tempering).
