SUS410/SUS420J2/SUS430 stainless steel beads Comparison

SUS410: Martensite represents the steel grade, with high strength and high hardness (magnetic); poor corrosion resistance, not suitable for use in severely corrosive environments; low C content, good workability, and the surface can be hardened by heat treatment.

SUS420J2: Martensite represents the steel grade, with high strength and high hardness (magnetic); poor corrosion resistance, poor processing and formability, and good wear resistance; it can be heat treated to improve mechanical properties. It is widely used for processing knives, nozzles, valves, rulers, and tableware.

SUS430: Low thermal expansion rate, good molding and oxidation resistance. Suitable for heat-resistant appliances, burners, home appliances, class 2 tableware, kitchen sinks. Low price, good workability is an ideal substitute for SUS304; good corrosion resistance, typical non-heat treatment hardenable ferritic stainless steel.

Principle of stainless steel ball:

Stainless steel beads 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 beads 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.
