36.5125mm(1-7/16"), Hot Sale Solid Stainless Steel Metal Ball For Bearing
 
Introduction

 

Stainless steel balls are usually produced by the stainless steel forging process. At this stage, the commonly used stainless steel balls are 201, 302, 304, 316, 316L, 420, 440C.

 

Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel according to the state of organization. In addition, it can be divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel, etc.

 

Main features


Weldability, Polishing performance, Heat resistance, Corrosion resistance

 

a.The main factors affecting polishing performance are as follows:
① Surface defects of raw materials. Such as scratches, pitting, pickling, etc.
②Material problems of raw materials. If the hardness is too low, it is not easy to polish during polishing (BQ is not good), and if the hardness is too low, orange peel will easily appear on the surface during deep drawing, which will affect the BQ. BQ with high hardness is relatively good.
③After deep drawing, small black spots and RIDGING will appear on the surface of the area where the deformation is extremely large, which will affect the BQ.

 

b.Heat resistance refers to the ability of stainless steel to maintain its excellent physical and mechanical properties at high temperatures.

 

c.When the number of chromium atoms in the steel is not less than 12.5%, the electrode potential of the steel can be changed abruptly, from a negative potential to a positive electrode potential. Prevent electrochemical corrosion.

 

Structural composition


The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, the maximum does not exceed 1.2%, and the ωc (carbon content) of some steels is even lower than 0.03% (such as 00Cr12 ). The main alloying element in stainless steel is Cr (chromium). Only when the Cr content reaches a certain value, the steel has corrosion resistance. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu.

 

Compared with carbon steel, austenitic stainless steel has the following characteristics:
 

1) High resistivity, about 5 times that of carbon steel.
2) Large linear expansion coefficient, 40% larger than carbon steel, and as the temperature increases, the value of the linear expansion coefficient increases accordingly.
3) Low thermal conductivity, about 1/3 of carbon steel.

 

304 stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes, but in severely corrosive industries or marine atmospheres, it is best to use 316 stainless steel.
