2.Chrome Steel Bearing Ball
Chrome steel AISI52100 is a universal material for many applications. Troughout the manufacturing
process, statisical process control assures tolerance accuracy, fine surface finish and a consistent
high quality.
Feaure | Universal material for ball and roller bearing industry.Chrome steel balls contain chromium and to through hardening has an excellent surface quality and load bearing | ||||
Hardness | Excellent hardness control with a through hardness of HRC 60 to 67 | ||||
Size Avaliable | chrome steel ball 1mm-100mm | ||||
Grade | G10-G1000 | ||||
Application | Universal for many applications. For example: balls & roller bearings. | ||||
Material Conversion | ASTM/AISI | DIN | W - Nr | NF | JIS |
52100 | 100Cr6 | 1.3505 | 100C6 | SUJ2 | |
Carbon | Chromium | Manganese | Silicon | Sulfur | Phosphorous |
0.98 to 1.10% | 1.30 to 1.60% | 0.25 to 0.45% | 0.15 to 0.35% | 0.025% | 0.025% |
3. Stainless Steel Ball Specification:
Material | Feature | General Applications |
AISI 420 | Magnetic, Harden-able, fair corrosion resistance. | used for special bearings and valves where Balls requiring a combine action of hardness and corrosion resistance |
AISI 440C | Magnetic, highest hardness, good corrosion resistance | used in bearing nozzles and valves where lubrication is poor or absent |
AISI 304 | austentitic, corrosion resistance, slightly magnetic, however annealing can makes it non - magnetic | Used in valves and relevant application, food products, aerosols, home sprays, perfumes and medical equipment. |
AISI 316 | non - magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid. | used in presence of sulphuric, phosphoric and acetic acids.Mainly used in chemical, paper and textile industries. |
AISI 316L | Characteristics same as 316 but with excellent corrosion resistance, Lower carbon content than regular 316. | expecially used in Jewelry, and Human Implant Applications |
