11.906mm(15/32"), Solid stainless steel metal ball for bearing, G100/G200
Introduction
Stainless steel balls are usually produced through a forging process. At present, commonly used stainless steel balls are made of 201, 302, 304, 316, 316L, 420 and 440C.
Definition: Steel with a chromium content of more than 12% and resistance to chemical substances.
Principle: Stainless steel does not rust, but it is not easy to rust.
We mainly export stainless steel balls (201, 304, 316, 420, 420C, 440C, 430), and also produce chrome steel balls (AISI52100, 100CR6, GCR15), carbon steel balls (1015, 1010, 1045, 1085) and various other material of steel ball.
The relationship between the main chemical composition and the performance of stainless steel.
1. Carbon can increase hardness and strength, high content will reduce its ductility and corrosion resistance
2. Chromium can increase corrosion resistance, oxidation resistance, refine the grain, increase strength, hardness and wear resistance.
3. Nickel can increase high temperature strength, corrosion resistance, and reduce the rate of cold work hardening
4. Molybdenum increases strength and has excellent corrosion resistance to oxides and seawater
5. Copper is good for cold forming and reduces magnetic properties
6. Mn is mainly used to reduce the magnetic properties of the material, but the content should not be too high.
Stainless steel ball 304
Application:
304 stainless steel ball is widely used steel ball on the market. It can be used in medical equipment, chemicals, aviation, aerospace, plastic hardware, perfume bottles, sprayers, valves, nail polish, motors, switches, washing machines, refrigerators, air conditioners, and automobiles. Accessories, bearings, instruments, milk bottles.
Features:
A typical representative of austenitic steel, generally non-magnetic, but after passing through the photosphere, it will become magnetized and can be demagnetized, HRC≤28. Has good anti-rust and anti-corrosion properties.
Comparison:
304HC stainless steel balls are softer and easier to process than 304 stainless steel balls, while 304L stainless steel balls have stronger anti-rust and anti-corrosion properties than the above two kinds of balls, easy to weld, excellent polishability, and are more suitable for industries with higher surface requirements.
