44.45mm(1-3/4"), Large 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.
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.
Industry Standard Grade10 420 Stainless Ball Bearings: High Quality Graded 420 Stainless Steel Ball bearings made from AISI 420 Stainless Steel with a hardness of 52 -55 HRC Rockwell Scale, the hardness is all the way through the ball. These are the same stainless 420 steel balls used to manufacture bearing assemblies and have a high duty and life cycle.
The most commonly used martensitic stainless steel giving fair corrosion resistance to fresh water, steam, petrol, alcohol, oils and foodstuffs.
Manufactured in compliance to the following international standards: AISI 420 / BS970 420S37 420S45 / DIN 1.4021, 1.4025, 1.4034 / AFNOR Z30C13, Z40C14 / JIS SUS 4200JI, 420J2.
Note: Ferritic stainless steel cannot maintain its strength at high temperatures, so it is not used when strength is needed.
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.
