36.00mm(1.41732"), Hot Sale Solid Stainless Steel Metal Ball For Bearing
Introduction
Stainless steel balls are usually produced through a stainless steel forging process. At present, the commonly used stainless steel balls are 201, 302, 304, 316, 316L, 420, 440C.
According to the organization state, stainless steel is usually divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel. In addition, according to the composition can be divided into: chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel and so on.
- Austenitic grade (300 series) is the most corrosion-resistant stainless steel grade. It is recommended to use forged solid/hollow ground stainless steel balls as bearings
When there is food contact. They are not ferromagnetic or ferromagnetic. They are not hardened.
- Martensitic grades (400 series) have corrosion resistance and high hardness. These grades are ferromagnetic. Forged solid/hollow ground stainless steel balls for bearings
They are mainly used where hardness, strength and wear resistance are required.
- Ferrite grades are ferromagnetic, but cannot be hardened or strengthened by heat treatment. They are more corrosion resistant than martensitic stainless steels, but not as good as austenitic stainless steels.
Main features
Weldability, polishing performance, heat resistance, corrosion resistance
a. Among them, the main factors affecting polishing performance are as follows:
① Surface defects of raw materials. Such as scratches, pitting, pickling, etc.
② The problem of raw materials. If the hardness is too low, it will not be easy to polish during polishing (BQ is not good), if the hardness is too low, orange peel will easily appear on the surface during deep drawing, which will affect BQ. BQ with high hardness is relatively good.
③ After deep drawing, small black spots and bumps will appear on the surface of the extremely deformed area, 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 may suddenly change from a negative potential to a positive potential. Prevent electrochemical corrosion.
Magnetic
The austenitic type is non-magnetic or weakly magnetic, and martensite and ferrite are magnetic. After austenite is cold-worked, its structure will also be transformed into martensite, and the magnetic properties will become larger. Therefore, the method of distinguishing the quality and the authenticity of stainless steel through magnet adsorption is one-sided and wrong.
