Application and Comparison of AISI 420c Stainless Steel Balls and Their Performance Parameters May 02, 2018

The specific understanding of AISI 420c stainless steel ball is that it uses the stainless steel ball made of AISI 420c stainless steel. Therefore, this specific name will be given so that everyone can have a clear understanding and correct understanding. Then, on this basis, we will continue to understand this steel ball knowledge in order to achieve the correct use and reasonable use of the product.


1. Is there a difference between AISI 420c and AISI420 in AISI 420c stainless steel balls? And what kind of application is this kind of stainless steel ball?

The AISI 420c in the AISI 420c stainless steel ball, which is a specific grade of stainless steel. If it is compared with the grade of AISI420, then there is no big difference because they are all martensitic stainless steels. Hardness, up to HRC55 or so. In addition, the six elements of carbon, silicon, manganese, phosphorus, sulfur, and chromium are included in the chemical composition. Also, there are corresponding regulatory requirements. They are:

Carbon: The content must not exceed 0.15%.

Silicon and manganese: their respective contents must not exceed 1%

Phosphorus: The content must not exceed 0.04%.

Sulfur: The content must not exceed 0.03%.

Chromium: The content should be in the range of 12% to 14%.


The application of the AISI 420c stainless steel ball is specifically for stainless steel bearings, slide rails and solenoid valves. Its advantages are high hardness, so it can be used in various types of machinery and bearings. Therefore, it can be seen in electrical equipment, instrumentation, home appliances, and transportation tools.


2. Mechanical properties of AISI 420c stainless steel ball

AISI 420c stainless steel ball, which also has the corresponding mechanical properties, is for the tensile strength, conditional yield strength, elongation, reduction of area and hardness, these are all very important performance parameters, so one can not be missed . Moreover, some of these parameters also have corresponding symbolic representations.


3. Comparison of AISI 420c stainless steel ball and AISI 304 stainless steel ball

AISI 420c stainless steel ball and AISI 304 stainless steel ball, both of which are in the large range of stainless steel balls, are all made of stainless steel, except that they are not the same on stainless steel, the former is Austenitic stainless steel, the latter being martensitic stainless steel. Therefore, there is no comparability between them.
