Stainless Steel balls
The workhorse family — 300 series for corrosion, 400 series for hardness.
440C
440C Stainless Steel provides medium wear and mild corrosion resistance — an affordable hardened material (56-61 RC) suitable for valve, pump & bearing applications.
630SS (17-4PH)
17-4 PH provides superior corrosion resistance, good resistance to stress-corrosion cracking and erosion-corrosion. Used in valve and pump applications.
SS302 – SS304
Slightly magnetic stainless steels providing excellent corrosive properties. Used in food and chemical applications.
SS316
316 Stainless Steel provides superior corrosion resistance and higher resistance to pitting. Non-magnetic, used in valve and petroleum industries as well as food and dairy processing.
