AISI 1018 Steel Pipe

Free-machining grade AISI 1018 Steel Pipe belongs to the world’s most widely used grades. AISI 1018 Steel Pipe is easy to form, machine, weld, and fabricate alloy AISI 1018 Steel Pipe. Despite its high strength-to-weight ratio, cold-drawn tubing can be processed to provide a combination of desirable properties, including excellent surface quality, excellent micro-structure uniformity, good machinability, and high tensile strength. As a consequence of rolling in an Assel mill equipped with an end-loss-free unit, seamless mechanical tubing can be produced from solid round billets by rotary piercing. AISI 1018 Steel pipes are then processed through a multiple-pass sizing reducing mill and a rotary sizer. The 1018 AISI 1018 Steel Pipe listed for sale on this page is Pickled & Oiled and offered in a black, unground state. We additionally offer this material with a ground and polished finish. AISI 1018 Steel Pipe Cold Drawn Seamless Tube is the primary tubular steel used in the manufacturing of Race Cars in the NASCAR racing series.

AISI 1018 Steel Pipe has a wide variety of applications. It is used for parts requiring cold forming, such as crimping, swaging, or bending. For severe bends, stress relieving may be necessary to prevent cracking. AISI 1018 Steel Pipe is highly suitable for carburized parts, such as gears, ratchets, worms, pinions, pins, chain pins, dowels, machine parts, non-critical components of tool and die sets, tool holders, etc. AISI 1018 Steel Pipe is used when good workability is required, on parts requiring threading, drilling, punching, and machining. AISI 1018 Steel Pipe is extensively used for mounting plates, spacers, and fixtures. C1018 is suitable for all applications that do not require the greater strength of high carbon and alloy steels.

AISI 1018 Steel Pipe mild/low carbon steel has excellent weldability, produces a uniform and harder case, and is considered the best steel for carburized parts. AISI 1018 Steel Pipe mild/low carbon steel offers a good balance of toughness, strength, and ductility. AISI 1018 Steel Pipe hot rolled steel has significant mechanical properties, improved machining characteristics, and a high Brinell hardness measure.
