Stainless Steel balls
The workhorse family — 300 series for corrosion, 400 series for hardness.
440C
Grade 100440C 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)
Grade 10017-4 PH provides superior corrosion resistance, good resistance to stress-corrosion cracking and erosion-corrosion. Used in valve and pump applications.
SS302 – SS304
Grade 200Slightly magnetic stainless steels providing excellent corrosive properties. Used in food and chemical applications.
SS316
Grade 200316 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.
