420 stainless steel ball characteristics and application

- Dec 29, 2017 -

As we all know, the so-called 420 stainless steel ball actually refers to the use of 420 stainless steel material obtained after processing the ball. 420 stainless steel is a martensitic stainless steel, this material has a certain degree of wear resistance and corrosion resistance, and higher hardness. In contrast, 420 stainless steel ball is mainly used in some of the precision and anti-rust properties are demanding industries.

 

Combined with the actual application of the situation, people often use the 420 stainless steel ball for a variety of precision machinery, bearings, electrical, equipment, instrumentation, transportation tools and household appliances and other production and processing. It is usually used to make parts that are resistant to atmospheric corrosion, water vapor, water and oxidizing acids. 420 stainless steel is 420 "cutting tool" martensitic steel, the performance is relatively close to Briggs high chrome steel the earliest stainless steel.

 

More importantly, this material is among the cheaper ones in stainless steel, with a hardness of 51 to 52 degrees, as well as magnetism and a certain degree of corrosion resistance and toughness. Due to different requirements, so the 420 stainless steel ball size also includes a variety of, mainly ranging from 2.0 to 25.4.

 

It is because of these characteristics of 420 stainless steel ball, so we can see that it is also often used for motorcycle parts, pulleys, stainless steel bearings, plastic bearings, handicrafts, valves and oil production operations. In fact, 420 stainless steel is a typical martensitic steel material, that is, we often say that stainless steel, has good anti-rust properties, high hardness HRC50-55.

 

In order to further improve its performance, in some applications where more stringent requirements, the 420 stainless steel ball after polishing, but also need to be passivated, which can strengthen the 420 stainless steel ball corrosion resistance.
