Precision ST45 Cold Drawn Steel Pipe For Mechanical Parts In
Machinery Equipment
Introduction
Precision Steel Tube ST45 for Mechanical parts is a cold finished
steel tube which offers uniform tolerances, enhanced machinability
and increased strength and tolerances compared to hot-rolled
products. The cold finished process increases the tube's physical
properties and offers better tolerances and reduced machining
allowances over hot finish seamless.
