Hot Rolled Steel Products and shapes
Hot Rolled Steel is available in many shapes, grades and sizes. Choose from the selection below.
Hot rolling involves the production of sheet metal from billets by passing the steel through rollers while above its recrystallization temperature to desired physical dimensions. Multiple passes through the rollers may be necessary to produce the final dimensions. Read more about the differences between hot and cold rolled steel.
Hot Rolled tubing is available in: Electric Resistance Welding (ERW), Cold Drawn Seamless (CDS), Drawn-Over-Mandrel (DOM), Hydraulic and Hot Finished.
Grade Summary: ASTM A36 is is the most commonly available of the hot-rolled steels which has good overall mechanical properties, is easily fabricated and may be formed hot or cold. Due to the hot roll process the surface on this steel will be rough when compared to cold rolled. ASTM A36 yield strength is also less than C1018.
Typical Applications: Trailers, Walkways, Ramps, Structural support, general fabrication
Available products: Round Bar, Rectangular Bar, Square Bar, Flat Sheet, Angle, Channel, Beam and Plate

Grade Description: A low carbon steel having a higher manganese content than mild steel and various other low carbon steels. Higher manganese makes this a better steel for carburized parts since it produces a harder and more uniform case. It also has higher mechanical properties, including Brinell Hardness, and better machining characteristics. Special manufacturing controls result in a quality product suitable for applications involving forging, heat treating, cold drawing, machining, etc.
Typical Applications: Gears, pinions, worms, king pins, chain pins, ratchets, dogs, oil tool slips and liners, studs, anchor pins, special bolts, tie rods. Any carburized parts requiring hard surface and soft core.
Analysis: C – .15/.20 Mn – .60/.90 P – .04 Max. S – .05 Max.

Machinability: 78% of B1112. Weldability: Easily welded by all welding processes, and the resultant welds and joints are of extremely high quality. Grade of welding rod used depends on welding conditions such as thickness of section, design, service requirements, etc. Forging: Heat to 2150º – 2250º F. Normalizing: Heat to 1650º – 1750º F. Annealing: Heat to 1550º – 1650º F. Cool in furnace. Hardening: This grade will respond to any of the standard carburizing methods and subsequent heat treatments. For a hard case and a tough core, carburize at 1650º – 1700º F for approximately 8hrs, cool in box, reheat to 1400º – 1450º F, quench in water and draw at 300º – 350º F.
