Stainless Steel Ball Feature:
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, and body jewelry and so on.
Stainless steel (AISI 304)
There are many kinds of stainless steel balls, AISI 304, AISI 316, AISI 316L,
AISI 420, AISI 420C, AISI 440, AISI 440C.AISI 304 steel balls have no good hardness
but offer good corrosion resistance, they offer good resistance to atomospheric corrosion,
dyes, food processing, valves, sex products and so on.
Stainless steel (AISI 201)
201stainless steel balls can be used in construction decoration, architectural decoration
architectural ornament, building decoration, Municipal engineering, municipal works,
public works, civil engineering, highway guardrail, hotel, market, armrest stair, public facilities.
It has acid and alkali resistance, high density, polish no bubbles, pinhole-free, best for decoration and industry.
