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.
Grade 25 AISI Type 420 Stainless steel balls afford the advantage of maximum hardness (50 Rockwell C ) and have fair-to-good corrosion resistance and good material strength. resist corrosion from alcohol, ammonia, food environments, fresh water, many petroleum products and organic materials and some mild acid environments. 420 Stainless steel is a high carbon martensitic Stainless steel and is often used in bearings, valves, dental and surgical instruments, cutlery, pump shafts, plastic molds and dies, steel balls, and various hand tools.
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.
