15mm 0.590inch AISI440c Stainless Steel Balls for Medical Instruments 13.8g

15mm 0.590inch AISI440c Stainless Steel Balls for Medical Instruments 13.8g

Creation Description

They exhibit very good mechanical qualities, toughness and corrosion resistance. AISI 304L gives lower carbon content material, AISI 302 greater mechanical characteristics. Balls are supplied in the passivated condition.


Unique bearings and pumps, aerosol pumps, gardening and family sprayers, perfume miniature pumps, seams, medical software valves, agricultural backpack sprayers. They are used in foodstuff, aerospace and navy business.

Corrosion Resistance 
Very very good corrosion resistance with regard to natural substances, oxidating solutions, foodstuff, sterilizing options. Excellent resistance with regard to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of very hot chloride solutions and to stress corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid remedies. AISI 302 demonstrates somewhat best corrosion resistance with respect to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be provided in the (1) Chilly Worked (HRC twenty-39, normal item) or (two) ANNEALED (HV one hundred-250, on need) circumstances.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly is dependent by the manufacturing approach, particular inquiries for not magnetic balls ought to priorly noted.
Precision Quality** On specifical ask for and for massive quantities, we can offer G10 and G16 precision quality balls. Diameters from three.000 mm to 1/2".
Precision Quality** On specifical request we can source G20-24-25-28-forty-48-fifty-sixty-80 precision grade balls.
