SUJ304/SUS304L/SUS304Cu stainless steel balls Comparison:

SUS304 stainless steel balls: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability  such as stamping and bending, no heat treatment hardening phenomenon, non-magnetic. Widely used in household products (category 1, 2 tableware), cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical appliances, building materials, chemicals, food industry, agriculture, and ship parts.

SUS304Lstainless steel balls: austenitic  basic steel, the most widely used; excellent corrosion resistance and heat resistance; excellent low temperature strength and mechanical properties; single-phase austenite structure, no heat treatment hardening phenomenon (non-magnetic, use temperature -196– 800°C).

SUS304Cu stainless steel balls: Austenitic  stainless steel with 17Cr-7Ni-2Cu as the basic composition; excellent formability, especially good wire drawing and ageing crack resistance;-the same corrosion resistance as 304.

Principle of stainless steel ball:

Stainless steel balls are not rust-proof, but not easy to rust. The principle is that by the addition of chromium, a dense chromium oxide layer is formed on the surface of the steel, which can effectively block the re-contact between the steel and the air, so that the oxygen in the air cannot enter the steel ball, thereby preventing The effect of steel balls rusting.

China National Standards (CNS), Japanese Industrial Standards (JIS) and American Iron and Steel Institute (AISI) use three digits to indicate different stainless steels, which are widely quoted in the industry, of which the 200 series is chromium-nickel-manganese-based austenitic Stainless steel, 300 series is chromium-nickel austenitic stainless steel, 400 series chromium stainless steel (commonly known as stainless iron), including martensite and ferrite.
