ball bearing stainless steel 420&304 material

ball bearing stainless steel 420&304 material

Compared with normal bearings,ball bearing stainless steel material not only have obvious advantages in material quality.But also much stricter control in technology and accuracy. During the working,stainless steel bearings work stably, low noise, are corrosion-resistant, and are widely used.

Common materials include 420,440,304,316...etc.

Advantage
1. Corrosion resistance: It is not easy to rust and has strong corrosion resistance.
2. Stainless steel bearings can work in liquids.
3. Long service life, if the speed and load are low, lubrication is not necessary.
4. High heat resistance: can be used in environments ranging from -60 ℃ to+300 ℃.

Ball Bearing Stainless Steel-420

420 stainless steel is a type of martensitic stainless steel.
Advantages: Chromium containing alloy can meet the low requirements of anti-corrosion and rust prevention.With lower smelting cost, lower price, low carbon content, and good processing performance.

Disadvantages: it doesn't contain nickel. It cannot be used in contaminated areas and cannot be used outdoors. Prolonged use can cause rust.

It has certain wear and corrosion resistance, high hardness, and is suitable for various precision machinery. Bearings, electrical, equipment,instruments, transportation tools, household appliances, etc. Mainly used for manufacturing components that are resistant to atmospheric, steam, water, and oxidative acid corrosion.

Ball Bearing Stainless Steel-304

304 stainless steel is an austenitic non-magnetic stainless steel with better corrosion resistance and diamagnetism.
The most important elements in 304 are Ni and Cr, which directly determine the corrosion resistance and diamagnetism of 304 stainless steel. Standard: Ni content greater than 8%, Cr content greater than 18%.

Advantages: Non magnetic; Superior corrosion resistance; High temperature resistance.
Deep stamping, bending, and other room temperature processing properties are good, and will not harden after heat treatment.
Suitable for high-speed or even extremely high speed operation, and very durable without frequent maintenance.
Used in industries such as food production equipment, Xitong chemical equipment, precision instruments, low noise motors, automobiles, motorcycles, and general machinery.
