1.15mm 0.045inch AISI304 Stainless Steel Balls for Seat Belt Locking Mechanism

1.15mm 0.045inch AISI304 Stainless Steel Balls for Seat Belt Locking Mechanism

 Generation Description

They display very good mechanical qualities, toughness and corrosion resistance. AISI 304L gives lower carbon content, AISI 302 better mechanical characteristics. Balls are offered in the passivated issue.


Stainless steel balls are commonly utilised in bearings, automobiles, bikes, bicycles, family appliances, chemical machinery, textile machinery, foods machinery, mining machinery, instruments, and other fields.

Corrosion Resistance 
Quite excellent corrosion resistance with respect to natural and organic substances, oxidating options, foodstuff, sterilizing remedies. Good resistance with respect to atmospheric corrosion and dyes. They are subjected to pitting and crevice corrosion in existence of scorching chloride solutions and to tension corrosion when temperature exceeds 60°C. They do not resist to sulfuric acid solutions. AISI 302 shows marginally very best corrosion resistance with regard to AISI 304/304L stainless steels.


Property  Description
Hardness* Balls can be supplied in the (1) Chilly Worked (HRC 20-39, normal merchandise) or (two) ANNEALED (HV one hundred-250, on demand from customers) problems.
Magnetism Eventual magnetism of AISI 316 balls and in basic of all austenitc stainless steels strictly depends by the production procedure, distinct inquiries for not magnetic balls need to priorly reported.
Precision Grade** On specifical request and for huge portions, we can source G10 and G16 precision quality balls. Diameters from three.000 mm to 1/two”.
Precision Grade** On specifical request we can source G20-24-25-28-40-48-50-60-eighty precision quality balls.
