Hollow 440A Stainless Steel Balls
 |
These lightweight balls are often used in floats, valves, and other parts to regulate liquid level and flow. Made of 440A stainless steel, they resist impact and corrosion in temperatures up to 250° F. Their polished surface prevents contaminants from sticking to them.

Impact-Resistant 440A Stainless Steel Sheets
 |
A good choice for cutlery and valve components, 440A stainless steel absorbs impacts and bends instead of suddenly breaking. It contains less carbon than 440C stainless steel, so it's tougher and not quite as hard. It also maintains its corrosion resistance in temperatures as hot as 1920° F.
