Products Description
STAINLESS STEEL BALL
Stainless steel is a steel alloy that contains more than 11% chromium. This type of steel has high resistance to corrosion by
chemicals (acids, alkalis, salts). Therefore, it solves traditional steel’s corrosion problem and provides excellent resistance to
rust and coloring.

Feature and Application
Feature | General Applications | |
AISI 420 | Magnetic, Harden-able, fair corrosion resistance | Used for special bearings and valves where Balls requiring a combination 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 304L | Austenitic 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 sulfuric, phosphoric andacetic acides. mainly used in chemical, paperand textile industries. Applications include aerosol, sprayers, finger pump mechanisms, milk machine blenders, food processing equipment and medical applications |
AISI 316L | Characteristics same as 316 with excellent corrosion resistance, Lower carbon content than regular 316 | Used in Jewelry, and human implant applications |
