Products Description

Heavy Caliber Thick Wall Cold Drawn Seamless Steel Pipe

Advantages of Heavy Caliber Thick Wall Cold Drawn Seamless Steel Pipe

In boiler systems, the medium carbon 1045 chemistry combined with cold working reduces the tendency to thermal cycle cracking under repeated heating and cooling cycles.
In automotive component applications, the excellent tensile and yield strengths of Heavy Caliber Thick Wall Cold Drawn Seamless Steel Pipe make it an ideal choice for drive shafts, axles, and crankshaft bushings subjected to torsion and bending loads.
In the mechanical field, its significant wear resistance can extend the service life of sliding and rolling contact applications such as hydraulic pistons and bushings.

Applications of Heavy Caliber Thick Wall Cold Drawn Seamless Steel Pipe

Hydraulic cylinders
Machine parts requiring high strength and reliability
