60.00mm(2.3622"), Large Solid RoHS SGS Stainless Steel Metal
Ball For Bearing, G100
Product description
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.
304 is a versatile stainless steel, which is widely used to make
equipment and parts that require good overall performance
(corrosion resistance and formability). In order to maintain the
inherent corrosion resistance of stainless steel, steel must
contain more than 18% chromium and more than 8% nickel.
Three quality stainless steels are available for applications in corrosive environments. AISI Type 440C offers the greatest hardness and surface finish, and is available in double vacuum melted materials. AISI Type 302 provides extreme toughness and corrosion resistance from oxidizing solutions and many organic chemicals in an unhardened state.
Hardness of 302, 316, 316L Stainless Steel Balls
Non-annealed hardness, uniform throughout, as measured on parallel flats, is typically Rockwell “C” 25 to 39. Annealed hardness, available on request, is typically Rockwell “B” 75 to 90.
Hardness 440A stainless steel hardness as measured on parallel flats is Rockwell "C" 52-60.
Type 430 stainless steel is an economical stainless material that provides corrosion resistance at low cost. Typical applications for this product include cosmetic mixing media, decorative trim, and light duty ball valves.
Hardness 430 stainless steel is a non-hardenable stainless steel.
Note: Ferritic stainless steel cannot maintain its strength at high
temperatures, so it is not used when strength is needed.
All stainless steel balls
are passivated. 420 stainless steel balls available on request.
The relationship between the main chemical composition and the
performance of stainless steel.
1. Carbon will increase hardness and strength, high content will
reduce its ductility and corrosion resistance
2. Chromium can increase corrosion resistance, oxidation
resistance, refine grain, increase strength, hardness and wear
resistance
3. Nickel can improve high temperature strength, corrosion
resistance, and reduce cold work hardening rate
4. Molybdenum improves 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.
