RMP Carbon Steel A500B Round Tube, 2-3/8 Inch OD x 0.154 Inch Wall

The term "hot roll" refers to the hot rolling mill process. The steel is heated above its re-crystallization temperature and rolled into the desired thickness. Hot rolled material is not polished or finished and is ideal for projects where the finish of the material is not critical. It is most often cheaper than metals with a more expensive process.
