Products description:
Seamless Steel Carbon Steel Pipe
Cold Rolled Seamless Mechanical Tubing is a cold rolled steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. The cold rolled process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.
Benefits of Round Cold Rolled Seamless Mechanical Tubing:
Superior surface finish
Dimensional accuracy and excellent micro-structure uniformity
Enhanced machinability
High strength to weight ratio
Tight tolerances, resulting in reduced machine time
Applications: hydraulic cylinders, rollers, structural apps, truck and automotive parts.
