SOME OTHER STAINLESS STEEL BALLS INTRODUCTION

Stainless steel (AISI 316)
AISI 316 steel balls have no good hardness, but have better corrosion resistance than AISI 304, AISI 316 stainless steel balls offer good corrosion resistance to sulphuric acid compounds. They are used in nail polish, trigger sprayers, dispenser valves, body jewelry and so on.
AISI 316 stainless steel balls in our factory:
Minimum diameter :2mm
Best precision :G100
Hardness :HRc25-39
 
Stainless steel (AISI 316L)
AISI 316L  type stainless steel ball has lower carbon content than AISI 316 material, which offers ever higher corrosion resistance, also gives excellent resistance to sulphuric acid compounds. Usually used in valves, jewelry and medical uses.
AISI 316L steel ball in our factory:
Minimum diameter :2mm

Minimum diameter :1.2mm
Best precision :G10
Hardness :HRc52
 
Stainless steel (AISI 420C)
AISI type stainless steel balls have the advantage of maximum hardness combined with corrosion resisting properties, 420C balls have a slightly higher hardness range than 420. Its fine surface finish, also makes them especiall useful in bearings and valves and other severe environment applications.
AISI 420c stainless steel balls in our factory:
Minimum diameter: 1.2mm
Best precision: G10
