The steelmaking process begins with our raw material recycled scrap metal.
Electric arcs jumping across three carbon electrodes in the roof of each furnace create controlled lightning.
After being melted, the ladle of steel is carried by crane to the refiner.
At our Faircrest Plant, steel is bottom poured into ingots.
At the Harrison Steel Plant, we cast steel blooms in our strand caster, designed to produce extremely clean bar products.
Large starting cross-section sizes provide improved grain structure in the finished steel product.
The billets are transferred to the piercing mill, where they are drawn by two rotating drive rolls over a bullet-shaped piercing plug.
A variety of thermal treatments are available to provide the necessary strength and toughness, or the optimum hardness and microstructure for customer processing requirements.
Routine visual inspections combine with automated testing systems to ensure the quality and dimensions of our tubes.
Our tube products meet straightness tolerances through either rotary straightening equipment or press straightening.
Tubes are cut to standard lengths, or to customer-specified lengths.
Each tube is spray-labeled with product data that enables easy identification, and tracking the tube back to a specific heat of steel.
Each heat of steel is rigorously evaluated as it moves through the process.
In addition to surface and dimensional quality checks, steel product samples are evaluated using a number of laboratory tests.
Timken seamless tubes can be cut to the customers required length before shipping.
