Stainless steel Basic Information:
Material :AISI 201,304,316,420,430,440
Size Range :0.35mm - 200mm
Grade:G100 G200 G500 G1000
Feature:Corrosion Resistance
We can prodive different material stainless steel balls :
AISI 304
Feature: Austenitic, corrosion resistance, slightly magnetic, however annealing can make it non-magnetic
General Applications: Used in valves and relevant application, food products, aerosols, home sprays, perfumes and medical equipments.
AISI 316
Feature: non-magnetic, good corrosion resistance even when exposed to marine atmosphere and sulfuric acid.
General Applications: used in presence of sulphuric, phosphoric and acetic acides, Mainly used in chemical, paper and textile industries.
AISI 316L
Feature: Characteristics same as 316 but with excellent corrosion resistance. Lower carbon content than regular 316.
General Applications: Especially used in Jewelry, and Human Implant Applications
AISI 420
Feature: Magnetic, harden-able, fair corrosion resistance
General Applications: Used for special bearings and valves where balls requiring a combination of hardness and corrosion resistance
AISI 440C
Feature: Magnetic, highest hardness, good corrosion resistance.
General Applications: Used in bearing, nozzles and valves where lubrication is poor or absent.
