Generation Description
 

AISI 302/304/304L STAINLESS Steel BALLS

They show very good mechanical qualities, toughness and corrosion resistance. AISI 304L offers lower carbon material, AISI 302 far better mechanical traits. Balls are offered in the passivated condition.

Corrosion Resistance

Extremely great corrosion resistance with respect to natural substances, oxidating answers, foodstuff, sterilizing solutions. Very good resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in presence of hot chloride answers and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 displays slightly best corrosion resistance with regard to AISI 304/304L stainless steels.

Notes

Property	Description
Hardness*	Balls can be provided in the (one) Cold Labored (HRC 20-39, normal solution) or (two) ANNEALED (HV a hundred-250, on need) problems.
Magnetism	Eventual magnetism of AISI 316 balls and in standard of all austenitc stainless steels strictly is dependent by the production process, particular inquiries for not magnetic balls should priorly described.
