Hot rolled in the form of coil and plate is a type of steel product produced from hot rolling process. Plants and users of this type of steel normally call this product to differentiate it from the cold rolled commonly known as Hot rolled product can be provided in the form of coils and plates. The condition can be in the form of coil or product through pickling and oiling process (hot rolled coil-pickled oiled or HRC-PO).The use of black steel includes applications as listed below: General Construction and Welding, Pipes and Tubes, Automotive Components and Frameworks, Oil and Gas Pipeline, Oilwell Pipe Cases & Tubes, Gas Tubes, Weather Corrosion Proof Steels, Rerolling, Ship Constructions.
Black steel pipes and tubes can be cut and threaded to fit your project. Fittings for this type of pipe are of black malleable (soft) cast iron. They are connected by screwing onto the threaded pipe, after applying a small amount of pipe joint compound on the threads. Larger diameter pipe is welded on rather than threaded. Black steel pipe is cut either with a heavy-duty tube cutter, cut-off saw or by a hacksaw.
