316L stainless steel square tube stainless steel pipe
Uncoated black steel, also called black malleable iron, is made from corrosion-resistant ungalvanized steel and includes a scaly, dark-colored iron oxide coating on the surface. Uncoated black steel pipe connects with fittings to transport gas and water, protect electrical wiring, or deliver high-pressure steam and air. Uncoated black steel and iron are available in pipe lengths longer than 12" and nipple lengths 12" and shorter. |
